5/64 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 shaft-to-hub retention, light drives, or spacer assemblies, check the drilled-hole range, pin length, and access for driving the pin squarely. 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.
