1/4 x 13/16 Tension Pin (Slotted Spring Pin) is a spring steel slotted pin used where the pin must compress on entry and push back after seating. Use the three names together when cross-checking older maintenance notes, bills of material, or shop requests. The retaining action comes from spring force and friction at the hole wall, not from threads, adhesive, or staking.

Common uses include agricultural equipment linkages, outdoor mechanisms, and repair assemblies, where the pin retains parts without a threaded fastener. For worn precision holes, 0.001 Oversize Dowel Pins may be the better repair path than using a spring pin.
