ASME B18.7 covers complete general and dimensional data for semi-tubular rivets, full tubular rivets, split rivets, and rivet caps for use In general purpose applications. The products described are suitable for joining metallic and nonmetallic materials or combinations thereof. It should Lw noted that whIle these products are suitable for general purpose asseniNy, other special purpose types are available to satisfy particular requirements and manufacturers should be consulted for spedal requirements.
1.1.2 The inclusion of dimensional data in this Standard is not intended to imply that all of the products described are stock production sires. Consumers are requested to consult with suppliers concerning availability of products.

23 MateriaL
Semi-tubular and lull tubular rivets shall be made from low carbon steel (0.1% carbon or less) (UNS G10050). commercial yellow brass (UNS C26SOO), copper (UNS C14700), aluminum (UNS A95052), or other materials as agreed upon between the manulachirer and the purchaser
2.6 FinIsh
Unless otherwise specified, rivets shall be supplied with a natural (as processedt finish. unplated or uncoated. Rivets may be furnished plain (bare metal) oc with a protective coating (electrodeposiled 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 he 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 o 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 6nihea are e1y hard and. theteIoi’e, will have a Iendrncv to flake off the end of the revet when it Is si by the user
2.7 Workmanship
The rivets shall be fwe from all burrs, seams, or other Imperfections that might Impair their usability. Rivets are not machined or trimmed, and unevenness of the tubular end shall not be such that the usability of the rivet shall be impaired, when clinched with properly aligned, appropriate setting tools.
