Dimensional specifications per ASME B18.2.1

STANDARD THREAD LENGTH
 

Bolt lengths 6
Bolt lengths > 6

Thread length = (2 X diameter) + 1/4 Thread length = (2 X diameter) + 1/2

MANUFACTURING

Anping Top manufactures hex bolts from 3/8 diameter through 2-1/2 diameter in most ASTM, and SAE specifications.   Special tooling can be created to produce nonstandard head dimensions or bolt heads with your companys name and/or logo.
 

Note

Hex bolts (six sided heads) are the industry standard for fasteners with forged heads.  ASTM A307 grade A bolts, all SAE bolts, and several other common specifications require a standard (finished) hex head.  For specifications such as A307 grade B, A325 and A490 that require a heavy hex head, refer to dimensional tolerances for Heavy Hex Bolts or Heavy Hex Structural Bolts.
