3/16 x 5/8 Tension Pin (Slotted Spring Pin) helps retain mating parts through spring force against the hole wall. Tension pin, slotted spring pin, and roll pin describe the same slotted self-retaining pin style. The published OD range of 0.194-0.199 in. is larger than the 0.187-0.192 in. recommended hole range by design.

This size is often reviewed for fixture stops, temporary tooling, and production aids 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 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.
