3/16 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 handles, knobs, and control levers, the headless form keeps the joint compact after installation. Where stainless material and precision location are both required, 18-8 Stainless Steel Standard Dowel Pins may fit the drawing better.

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.
