FAQ

What are STI threads?
"STI" stands for Screw Thread Insert. They're oversized internal threads designed to receive an
insert like a Heli-Coil. Our screws match that size externally

Why not just do it myself?
Although a simple part, it can be very time consuming for a shop to drop what they are doing and make these. We price these to be more efficient than doing it yourself, so you can get back to parts that pay.
