FAQ

What tool fits a penta head bolt?
A penta socket sized for the head. A standard hex wrench won't turn it, which is why utilities use them.

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.
