5/32 x 2 1/2 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. The chamfered ends support driving from either side, while the open slot allows compression during installation.

In replacement assemblies, legacy equipment, and maintenance repairs, the headless form keeps the joint compact after installation. When the design requires repeatable precision location, compare Heat Treated Steel Standard Dowel Pins with a reamed hole and ground pin.

Cold Headers can assist when drawings, service records, and replacement needs call for an exact spring pin size. Review the verified OD, hole-size, shear, and length-tolerance data before matching this pin to a drawing or service record.
