FAQ

What wrench fits a stainless hex nut?
The same wrench as the matching hex cap screw: 7/16" for 1/4", 1/2" for 5/16", 9/16" for 3/8", 3/4" for 1/2" and 15/16" for 5/8".

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.

Can I use stainless with zinc plated or galvanized parts?
Use stainless nuts and washers with stainless bolts and screws. In wet conditions, stainless touching zinc plated, galvanized or aluminum parts can cause galvanic corrosion of the zinc or aluminum.
