11、ndards Committee B18, Subcommittee 7, has met periodically since 1979 to arriveat a metric standard to serve as a companion to ANSI B18.7. This Standard covers only oval headsemi-tubular rivets with straight holes. The Committee has declared its intent to expand thescope of the standard to include o
12、ther head styles, tapered holes, full tubular rivets, and rivetcaps as their use in metric dimensions become apparent. These other styles of rivets, althoughnot included here, are available from manufacturers, and the dimensions in this Standard shouldbe the basis for further development.Because sem
13、i-tubular rivets are used in automatic assembly machines, the concentricity of theoutside edge of the head to the rivet shank is an important functional attribute. On a low ovalhead rivet, the axis of the head is very difficult to find, and therefore the true head positionmethod of measuring concent

This was granted on J

The products described
21、are suitable for joining metallic and nonmetallic materi-als or combinations thereof. Although these productsare suitable for general purpose assembly, other specialpurpose types are available to satisfy particular require-ments, and manufacturers should be consulted for spe-cial requirements.1.1.2
22、The inclusion of dimensional data in thisStandardisnotintendedtoimplythatalloftheproductsdescribed are stock production sizes. Consumers arerequested to consult with suppliers concerning avail-ability of products.1.2 Types of RivetsThe rivets specified in this Standard include the fol-lowing.1.2.1 S
