1.5mm x 12mm Stainless Steel 420 Glenloch Spring Pin

Glenloch spring pins (also known as rolled pins or spring pins) have a body diameter larger than the hole diameter in the component being fastened, and a slight chamfer on the edge of the pins to guide the pin into the hole. A waved split in the pin allows compression and the force exerted by the pin against the wall of the hole locks it in place.
