FAQ
What does a cup point set screw do?
The cupped end digs into the shaft as it is tightened, holding a collar, pulley, gear or knob in place. Use a flat on the shaft for the best hold.
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.
