1/8 x 2 Tension Pin (Slotted Spring Pin) is intended for driven installation where the slot closes as the pin enters the 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 latch mechanisms, lock hardware, and service doors, 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 brings long-running industrial fastener experience to tension-pin quoting, cross-checking, and size confirmation. Review the verified OD, hole-size, shear, and length-tolerance data before matching this pin to a drawing or service record.
