Product Code:SAE J481
Title:Round Head Bolts (Cancelled Jan 1990)
Issuing Committee:Fasteners Committee
Scope:Round head bolts are made in two body styles: (a) A full size body, with a maximum diameter somewhat greater than the nominal diameter (not an SAE Standard except for ribbed neck bolts, Table 3); and (b) an undersize body, with a minimum diameter approximating the pitch diameter of the thread and a maximum diameter never exceeding nominal (SAE standard for all types except ribbed neck bolts). The body diameter of either style may be exceeded by a reasonable swelling or fin under the head, or under corners of the square necks, to the extent that serviceability is not affected.
