M10 x 1.5 x 1.5D Recoil Insert (10 Pack) 5230430 Boost Horsepower with Increased Scavenging:Recoil inserts are rolled from high quality stainless steel wire with a diamond shaped cross section, wound to the shape of a spring thread.

The inserts are greater in diameter than the corresponding tapped hole and compress as they are installed. This allows maximum surface contact
