FAQ

How long should the bolt be for an acorn nut?
The bolt must stop short of the dome. If it is too long, the nut bottoms out before it is tight.

How do I stop stainless threads from galling?
Stainless threads can seize (gall) when tightened fast or dry. Use an anti-seize compound, tighten at a slower speed, and do not over tighten.
