Rivet Tolerances

Out-of-Roundness of Head and Eccentricity of Head in Relation to Shank

Nominal Head Diameter	Total dial indicator reading resulting from eccentricity and out-of-roundess not to exceed.
Up to 1/4	0.015
over 1/4 to 3/8	0.020

Diameter of Rivet Head

Because the heads of these rivets are not machined or trimmed, the circumference may be irregular and the edges rounded or flat. The diameter of the rivet head shall be within -8 per cent and + 4 per cent of the nominal head diameter.
