7/32 x 3 3/4 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. A normal drilled hole at production tolerance is typically the economic advantage over precision reamed dowel-pin holes.

Common uses include conveyor guards, guide components, and light-duty brackets, where the pin retains parts without a threaded fastener. If the joint must locate parts precisely rather than retain them economically, a dowel pin is usually the product family to check.
