Request Information

1/4 x 1 1/2 Tension Pin (Slotted Spring Pin) uses spring action to hold itself in a prepared hole without an added head. In search and purchasing records, this part may be called a tension pin, slotted spring pin, or roll pin. For this diameter, the free OD is 0.258-0.264 in. against a recommended hole of 0.250-0.256 in., so the oversize is intentional.

In packaging equipment, changeover hardware, and machine covers, the headless form keeps the joint compact after installation. For blind holes where removal access matters, Pull Dowel Pins are the related locating-pin option to review.

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.
