Heavy Hex Bolts

Heavy hex bolt 320

Heavy Hex Bolts, (A 320)

An alloy or stainless steel hex bolt with a wider head than that of a standard hex machine bolt, manufactured in accordance with ASTM Standard A320.

Hex bolts (six sided heads) are the industry standard for fasteners with forged heads. ASTM A307 grade A bolts, all SAE hex 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 pattern, refer to dimensional tolerances for heavy hex bolts or structural bolts.
