5/32 x 1 1/2 Tension Pin (Slotted Spring Pin) uses spring action to hold itself in a prepared hole without an added head. In search and purchasing records, this part may be called a tension pin, slotted spring pin, or roll pin. For this diameter, the free OD is 0.162-0.167 in. against a recommended hole of 0.156-0.160 in., so the oversize is intentional.

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.
