7/16 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 0.448-0.459 in. against a recommended hole of 0.437-0.445 in., so the oversize is intentional.

For cabinet mechanisms, access panels, or hinged service hardware, check the drilled-hole range, pin length, and access for driving the pin squarely. Where stainless material and precision location are both required, 18-8 Stainless Steel Standard Dowel Pins may fit the drawing better.

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.
