3/32 x 1/2 Tension Pin (Slotted Spring Pin) gives a compact spring-steel fastening option for assemblies that need retention rather than ground-pin location. The catalog term is tension pin, while many drawings use slotted spring pin and many shops say roll pin. As the pin enters the hole, the slotted wall compresses and the spring steel reacts outward against the hole surface.
This size is often reviewed for packaging equipment, changeover hardware, and machine covers when a self-retaining driven pin is specified. If the joint must locate parts precisely rather than retain them economically, a dowel pin is usually the product family to check.
Cold Headers can assist when drawings, service records, and replacement needs call for an exact spring pin size. Review the verified OD, hole-size, shear, and length-tolerance data before matching this pin to a drawing or service record.
