Zinc Plated Steel Roll Pin 1/4″ x 3/4″

This slotted spring pin, also known as a roll pin or tension pin, is a hollow cylindrical fastener used to securely join parts by press-fitting into a drilled hole . It is made from hardened high-carbon spring steel and zinc-plated for corrosion resistance . The pin’s nominal size is 1/4″ in diameter by 3/4″ in length , and it features chamfered ends for easy insertion. When installed, the pin compresses to fit the hole and exerts spring tension against the hole walls, self-locking in place to resist loosening from shock or vibration .
