5/64 x 1 Tension Pin (Slotted Spring Pin) is a roll pin for assemblies where self-retention and simple drilled-hole preparation matter. The slotted construction is the reason this same fastener is commonly indexed as a spring pin or roll pin. The retaining action comes from spring force and friction at the hole wall, not from threads, adhesive, or staking.

In sheet metal stacks, alignment-plus-retention work, and panel assemblies, the headless form keeps the joint compact after installation. For worn precision holes, 0.001 Oversize Dowel Pins may be the better repair path than using a spring pin.

Cold Headers supports hard-to-find pin sourcing, including uncommon lengths and exact diameter-length combinations. Review the verified OD, hole-size, shear, and length-tolerance data before matching this pin to a drawing or service record.
