2.5 Material
Semi-tubular and full tubular rivets shall be made from low carbon steel (0.1% carbon or less) (LJNS G10050), commercial yellow brass (UNS C26800), copper (UNS C14700), aluminum (UNS A95052), or other materials as agreed upon between the manufachirer and the purchaser
2.6 Finish
Unless otherwise specified, rivets shall he supplied with a natural (as processed) Finish, unplated or uncoated. Rivets may be furnished pbiri (hare metal) or with a protective coating (elcctrodcposited 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 a.ssembk 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 an’ 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 Nkkel and chromium f.nnhrs are very hard and, thetelore, will have a tendency to flake off the end ot the rivet when It is set by the ir.
2.7 Workmanship
The rivets shall be Free (roni 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.

(a) nominal sine
(b) length (fraction or decimal equivalent)
(C) product name
