CROSS REFERENCE TO RELATED APPLICATION [0001] The present application claims priority under 35 U.S.C. .sctn.119(e)(1) to the provisional application entitled CATEGORIZING FASTENERS AND CONSTRUCTION CONNECTORS USING VISUAL IDENTIFIERS which was filed on Jul. 3, 1997 and assigned application Ser. No. 60/051652. FIELD OF THE INVENTION [0002] The present invention relates to a color coding system to identify the physical properties of fasteners and connectors both before and after their application. BACKGROUND OF THE INVENTION [0003] Modem building codes strictly control the types of materials and methods which may be used in building construction. These codes are primarily enacted to ensure that the resulting structures are safe. Failure to comply with the codes often results in the structure not being approved for habitation, and could expose the builder or developer to liability to the buyer. Furthermore, noncompliance results in delays in construction, and increased production costs, due to the time and expense of correcting the mistakes. [0004] In the past few years, the construction industry has gone through major changes. Structures have become more complex, construction schedules are tighter, the labor force generally has no formal training, and there are often language barriers which make it difficult for the labor force to fully understand instructions. Consequently, it has become increasingly difficult to build structures in full compliance with the governing building codes. [0005] The task of ultimately determining whether a structure has been built to code is generally assigned to building inspectors, structural engineers and superintendents. These individuals review a construction site for compliance with architectural blue prints and Uniform Building Codes. The purpose of this inspection is to ensure the safety of the structure by checking that the proper materials/fasteners/construction connectors have been used and in the correct manner. [0006] During the planning of a construction project, the architect will specify certain fasteners and construction connectors based upon their appropriateness to achieve the function they are to perform, and the applicable building codes which govern that type of use. Furthermore, different materials require that different fasteners be applied at specific spacings based on calculations made by the engineers and architect. After these fasteners have been incorporated into the structure by the builder, it is next to impossible for the inspector to know the precise characteristics of the fastener. This is because the portions of the fastener which remain exposed, such as the head of a nail, do not indicate the physical properties of the fastener which may be required by the codes or architect, such as its diameter (or gauge), length, weight, etc. Short of having the fastener removed for inspection, there is often no way to determine this. This problem also exists when verifying that the proper fastener has been used in combination with the proper construction connector, such as plate straps. Consequently, building inspections are more time consuming and costly. There is also increased risk of error, and thus corresponding risk to safety, as the inspector may inadvertently overlook improper fastener or connector uses. [0007] Prior attempts to solve this problem have been unsuccessful. For example, one such attempt is described in U.S. Pat. No. 5,511,917 issued to Charles F. Dickson, the entirety of which is incorporated by reference as if fully set forth herein. The Dickson patent describes a complex system in which numbers and clock like markings are inscribed into nail heads. The markings represent a pattern from which the length and/or gauge of the nail can be identified. However, because the size of the markings is limited by the size of the nail head, for very small nails, the markings cannot be distinguished unless one is within a close proximity (12'' maximum) to the nail due to the small size of the inscription. This limits the usefulness of such a marking system, because it would be difficult for building inspectors to determine accurate fastener use from a distance. Further, the Dickson patent states that the nail must be inserted in a specific orientation for the markings to be usable, or that an even more complex marking system providing orientation must be used. Clearly, such complex indicators do not provide the simplification needed by industry and inspectors. Furthermore, the markings taught by Dickson would be distorted by the impact of the driving tool/system, likely making the markings illegible. This system for inscribing distinguishing marks on the nail heads has not been widely adopted, if at all. [0008] Consequently, there exists a need for fasteners and connectors with readily identifiable indicators to determine their physical properties after they have been inserted. Furthermore, there exists a need for an efficient and easy method of determining the physical properties of fasteners after the fasteners have been used. SUMMARY OF THE INVENTION [0009] The present invention provides a color coding system, which may be used in conjunction with a lettering or symbol system, for identifying construction fasteners and any corresponding construction connector by size and type, both before and after application. Advantageously, the system of the present invention provides for more efficient identification, both in terms of increasing the accuracy of determining if the correct fastener or connector has been used, and in decreasing the time required to make such determinations. [0010] The present invention can be used to color code all possible types of fasteners and any corresponding construction connectors to designate their physical properties. These properties include, length, shaft length, leg length, shaft diameter (or gauge), width, crown width, thickness, weight, threads, threads per unit of measure, tip configuration, anchoring capabilities, composition, materials, substance treatment, variations in surface, or any other physical property of a fastener which can be determined. [0011] In the present invention, a different color is pre-selected to define a fastener property and is assigned to each of the most common (but not limited to) fasteners. After application of the color to the fastener, the color can be used to distinguish the physical and other characteristics of fasteners and thereby their intended use. The colors are chosen to best contrast with the background materials most common to the fasteners. The colors are also applied so that they may be determined from a distance after the fastener has been installed. The colors which may be used include those from the visible light spectrum, neon colors, fluorescent colors, and marking materials that fade over time if there is an instance when the color would distract from the finished structure. Moreover, two or more colors may be used on one fastener to connote different types of information such as one color identifying the composition of the fastener and another color its length, or other variations of the physical properties of the fastener. Letter designations corresponding to the fastener composition may also be added on top of color coding for further identification (e.g., G representing galvanized, R representing ring shank, V representing vinyl, and so on). Other types of symbols may also be used besides lettering to categorize the fasteners and connectors. [0012] A color code key, preferably in card or chart form, may then be provided which categorizes the physical properties of the fasteners by color. Architects and building planners may incorporate these colors directly into their blueprints or building specifications. If the construction site is provided with fasteners and connectors incorporating the pre-selected color scheme, workers using the fasteners and connectors of the present invention are more likely to select the correct fastener or connector for an intended application because they will be able to confirm the choice by comparing the color to that on the blueprints. Furthermore, a building inspector will be able to more quickly and accurately determine if correct fasteners and connectors have been used when the present invention is incorporated into a construction site, by simple color observation. [0013] Another benefit of the present invention is that the color coding system is also applicable to construction connectors that are used in conjunction with fasteners. Color coding the construction connector and the fasteners will make it readily apparent if the proper combination has been used. This is done by matching the proper fastener to the proper construction connector by marking a piece of the connector (e.g., hardware or strap) with an identifying color corresponding to the correct fastener. Further, when both the fastener and corresponding connector have been color coded in this manner, an inspector can stand at a distance and assess if the correct fastener (nail for example) was used with the connector because of the color(s) distinction. This will make the use and inspection of such construction connector/fastener applications visually identifiable. [0014] In one aspect of the present invention, there is provided a fastener comprising a shaft having a first end and a second end. An exposed portion is attached to the first end of the shaft, and an identifying color is on the exposed portion. The identifying color is pre-selected to correspond to at least one physical property of the fastener and is capable of being recognized by a person of normal vision from a distance of at least 10 feet, and more preferably from a distance of at least 18 feet, when the shaft has been fully inserted into a surface. In one embodiment, there is a second identifier on the exposed portion, the second identifier corresponding to at least a second specified physical property of the fastener. The second identifier may be a second color in addition to the first, such as red stripe or marking on a blue background, and/or the second identifier may be a letter or symbol. [0015] In another aspect of the present invention, there is provided a method of identifying physical properties of inserted fasteners from a distance. The method comprises applying a colored coating over the surface of an exposed portion of the fastener prior to using the fastener. The colored coating has been pre-selected to correspond to at least one physical property of the fastener. Then, the fastener is inserted so that the coloring on the exposed portion remains visible and may be determined by a person of normal vision from a distance. Preferably, the color of the exposed portion may be determined from a distance of at least 15 feet, and more preferably from a distance of at least 18 feet. [0016] In another aspect of the present invention, there is provided a method of identifying fastener physical properties during building inspection. The method comprises selecting a plurality of colors to apply to an exposed surface of a fastener. Each color of the plurality specifically connotes one or more properties of the fastener. One of the plurality of colors is applied to the exposed surface of the fastener having the properties that the color connotes, so that the color may be recognized by a person of normal vision from a distance of at least 18 feet. Then, the fastener is inserted into an object. A building inspector provided with a color key indicating the physical properties that each selected color connotes, will be able to readily determine the physical properties of the inserted fasteners, such as their length, gauge, or composition. [0017] In another aspect of the present invention, there is provided a construction joint comprising a first surface and a second surface. The first and second surfaces are subject to a regulation which requires specified physical properties for fasteners used to join the first and second surfaces. A fastener is used to secure the first surface to the second surface. The fastener has a colored portion which is exposed to view. The color of the colored portion has been pre-selected to define one or more physical properties of the fastener which correlate to those set forth in the regulation. The joint may be formed from two wood surfaces, two metal surface, two plastic surfaces, or any combination of these and other common construction materials. [0018] In another aspect of the present invention, there is provided a method of making a fastener with physical properties which are identifiable from a distance. The method comprises pre-selecting a plurality of colors where each color corresponds to at least one specified physical property of a fastener. Then a fastener having a known physical property is provided. A specified color of the plurality is then applied to the fastener so that the specified color may be determined from a distance, with the specified color having been pre-selected to define the known physical property of the fastener. [0019] In another aspect of the present invention, there is provided a fastener and connector system. The system comprises a connector which is required by regulation to be used with fasteners having specified properties. A first colored coating is on the connector, the first coating color having been pre-selected to indicate the fasteners which regulation permits may be used with the connector. The system also includes a fastener having the specified properties. A second colored coating is on the fastener, the second coating color having been pre-selected to define the specified physical properties of the fastener.
