7/32 x 1/4 Tension Pin (Slotted Spring Pin) is a hollow, headless spring pin with a slot running along its length. In search and purchasing records, this part may be called a tension pin, slotted spring pin, or roll pin. The pin OD is intentionally larger than the recommended hole before insertion, and the slot gives the diameter somewhere to close during driving.

This size is often reviewed for handles, knobs, and control levers 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 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.
