5/16 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.

Common uses include cabinet mechanisms, access panels, and hinged service hardware, where the pin retains parts without a threaded fastener. When the design requires repeatable precision location, compare Heat Treated Steel Standard Dowel Pins with a reamed hole and ground pin.

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.
