5/64 x 5/16 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 0.083-0.086 in. against a recommended hole of 0.078-0.081 in., so the oversize is intentional.

Common uses include cabinet mechanisms, access panels, and hinged service hardware, where the pin retains parts without a threaded fastener. If the joint must locate parts precisely rather than retain them economically, a dowel pin is usually the product family to check.

For repair operations, distributors, and OEM sourcing, Cold Headers can help match the item number, diameter, length, and standard. Review the verified OD, hole-size, shear, and length-tolerance data before matching this pin to a drawing or service record.
