Product Overview

These hex bolts have hexagonal heads and are for general purpose applications with a socket type installation tool or standard wrench. The standard bolt is compatible with standard nuts and washers of the same thread pitch, grade, and finish. Grade 8 bolts have a higher strength and are to be used with Grade 8 nuts. An alternative for using hex bolts without nuts is to place them directly into a compatible female threaded receptacle. They require a pre drilled hole or pre-tapped hole with compatible female thread. Available in various materials, grades, and finishes.

Customer Questions & Answers

Is this 3/16 stainless steel

Please let me know
Asked by: Reggie
The F593C headstamp shows it to be 304 stainless with a strength rating similar to grade 8 carbon bolts. To get the structural 316 stainless, the headstamp should read F593G. Stainless bolts with no stamp or S30400 or S31600 have no strength ratings and should not be used for structural or critical applications. Late but important.
