5/64 x 7/8 Tension Pin (Slotted Spring Pin) supports economical retention in hinges, pivots, and light mechanical joints. 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.

This size is often reviewed for electronics assemblies, appliance hardware, and light mechanical frames when a self-retaining driven pin is specified. 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.
