1/2 x 11/16 Tension Pin (Slotted Spring Pin) is a slotted roll pin selected when a normal drilled hole is preferred over a reamed dowel-pin hole. Tension pin, slotted spring pin, and roll pin describe the same slotted self-retaining pin style. As the pin enters the hole, the slotted wall compresses and the spring steel reacts outward against the hole surface.

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.
