1/4 x 1 1/4 Tension Pin (Slotted Spring Pin) is a spring steel roll pin for economical retention in a drilled hole. In search and purchasing records, this part may be called a tension pin, slotted spring pin, or roll pin. Compared with a dowel-pin fit, the tension pin is usually chosen when economical retention matters more than tenths-level location.

This size is often reviewed for jigs, fixtures, and shop tooling where precision location is not the driver when a self-retaining driven pin is specified. For blind holes where removal access matters, Pull Dowel Pins are the related locating-pin option to review.

Cold Headers brings long-running industrial fastener experience to tension-pin quoting, cross-checking, and size confirmation. Review the verified OD, hole-size, shear, and length-tolerance data before matching this pin to a drawing or service record.
