Hex Cap Screws, Grades 8

Hex Cap Screws, Grades 8

A hex cap screw is a six-sided bolt with a trimmed hex head and a washer face on the bearing surface. Informally, it is also called a Finished Hex Bolt. Hex cap screws have tighter tolerances than standard bolts of the same size, and so are often used where precise tolerances are needed. The standard hex screw specifications include ASTM A449 and SAE J429 Grade-8.
