FAQ

What nut fits a 3/4-10 stainless cap screw?
A 3/4-10 18-8 stainless hex nut, or a nylon insert lock nut where vibration is a concern, with a 3/4" stainless flat washer.

How do I stop stainless threads from galling?
Stainless threads can seize (gall) when tightened fast or under heavy load. Put anti-seize on the threads, tighten slowly at low speed, keep the threads clean and don't overtighten.

How strong are 18-8 stainless bolts?
18-8 stainless bolts to ASTM F593 have a minimum tensile strength of about 100,000 psi in 1/4" to 5/8" and about 85,000 psi in 3/4" to 1-1/2". That is stronger than Grade 2 steel but not as strong as Grade 5 or Grade 8.
