B71.5-1960

1. SCOPE 1.1 This Specification covers the dimensions and requirements of standard tubular and semi-tubular rivets, having oval, truss, and flat countersunk heads, in a range of sizes from 1/16 to 5/16 inches diameter. While standard materials, finishes, lengths, head forms and other such requirements are given, it is understood that many rivets differing in one or more of these respects are in common use. The inclusion of sizes and lengths herein should not be construed as indicating that all such sizes are regular stock production items. Suggested clinch allowances, which are useful for determining suitable rivet lengths, are given in Appendix A for reference purposes, but this information should not be considered as an integral part of the Specification.
