Finished Hex Nuts

Finished hex nuts are available in ASTM A563-A and are compatible with low carbon steel bolts such as ASTM A307, ASTM F1554 grade 36, SAE grade 2, and AASHTO M183.

SAE grade 5 and grade 8 nuts are also available in a finished pattern.

Hot Dip Galvanized nuts will be tapped oversize prior to coating to allow for the thickness of the bolts coating.
