3.4 Slots
3.4.1 The slots in split rivets are produced by either punching or broaching the rivet blanks (i.e., the method of manufacture imparting definite characteristics to the contour of the slot and rivet performance).
3.4.1.1 Basically, the broached or sawed slot rivet is used for piercing hard materials including light gages of sheet metal.
3.4.1.2 The punched slot rivet is satisfactory for use in lighter materials.
3.4.2 In selecting or specifying a split rivet, it is recommended that the manufacturer be consulted for the type best suited for the application. Accordingly, the slot widths, slot depths, and contour shall vary with the manufacturers’ standards and recommendations.
3.5 Material Split rivets shall be made from low carbon steel (UNS G10050), commercial yellow brass (UNS C26800), copper (UNS C14700), aluminum (UNS A95052), or other materials as agreed upon between the manufac- turer and the purchaser.
3.6 Finish Unless otherwise specified, rivets shall be supplied with a natural (as processed) finish, unplated or uncoated. Rivets may be furnished plain (bare metal) or with a protective coating (electrodeposited plating and/or chemical conversion coating) as specified by the user. All rivets shall be provided with a supplementary lubricant if necessary to meet the stated performance requirements without galling. The lubricant shall be clean and dry to the touch, shall not be irritating to normal skin, nor emit an unpleasant odor during rivet assembly. The performance of rivets that are furnished with a protective coating shall not deteriorate when the rivets are stored indoors for a period of 6 months. In cases where rivets are given a protective coating or are cleaned following delivery to the purchaser, the rivet producer shall not be held responsible for failure of the rivet to meet dimensional, mechanical, or performance requirements traceable to plating, coating, or cleaning practice. Lubrication (e.g., waxing) may improve the setting of the rivet.
NOTE: Nickel and chromium finishes are very hard, and there- fore will have a tendency to flake off the end of the rivet when it is set by the user.
3.7 Workmanship The rivets shall be free from all burrs, seams, or other imperfections that might impair their usability. Rivets are not machined or trimmed, and unevenness of the end shall not be such that the usability of the rivet shall be impaired, when clinched with properly aligned, appropriate setting tools.ASME B18.7 pdf download.ASME B18.7-2007 pdf free download
