M3 Roll Pin

Overview
===
This is a basic fastener called a roll pin, slotted spring pin, or tension pin. These are designed to replace M3 screws that various projects require in places where a alloy steel screw is overkill/too heavy etc etc.

The pins are hollow cylinders with a slot or slit placed longitudinally that allows for compression during insertion and should equally distribute stress throughout the screw hole. Please take note: One end of the pin is beveled. This goes into the hole firs
