Gibraltar 49121G Slip Fit Round Straight Locating Pin

Product Description

The GIBRALTAR 49121G is a slip fit round straight locating pin used to precisely position and align workpieces in fixtures, jigs, and tooling setups. Machined from low-carbon steel, it features a 0.4209 inch nose diameter with a slip fit tolerance, allowing controlled insertion and removal without binding. The pin measures 1.5 inches overall length with a 0.5 inch nose length and a 0.5 inch tail diameter. Machinists, toolmakers, and fixture builders rely on this type of pin to maintain repeatable part location during machining, assembly, or inspection operations.

This locating pin is suited for use in precision workholding fixtures in metalworking, fabrication, and manufacturing environments. It is designed for setups where a slip fit is required for easy pin removal between cycles. The 0.875 inch collar diameter provides a positive seating surface against the fixture body, keeping the pin stable under lateral load. A 0.125 inch chamfer length on the nose aids entry into the mating locating hole.
