Gibraltar 49107G Slip Fit Round Straight Locating Pin

Product Description

The GIBRALTAR 49107G is a slip fit round straight locating pin used in fixturing, jig building, and precision workholding applications. Machined from low carbon steel, this pin is designed to align and register components with repeatable accuracy. The nose diameter measures 0.2183 inches, the nose length is 7/16 inches, and the overall length is 1-3/16 inches. The collar diameter is 5/8 inches and the tail diameter is 5/16 inches. A 5/64-inch chamfer length on the nose aids entry into mating bores. This pin is not relieved and carries a tolerance of +0.0000 inches, indicating a true slip fit without interference. Typically installed by machinists, tool and die makers, and fixture builders.

This locating pin is suited for use in production jigs, assembly fixtures, and machine tool setups where consistent part registration is required. The slip fit design allows parts to seat and remove freely without binding, making it appropriate for applications with repeated loading and unloading cycles. The collar provides a positive stop against the fixture plate surface, controlling insertion depth. Package quantity is one pin per unit.

Installation Notes

Installation is performed by machinists or toolmakers during fixture assembly or maintenance. Before pressing or seating the pin, ensure the mating bore is clean and free of chips, burrs, or debris. Slip fit pins should seat by hand or with light mallet pressure only — do not force or drive with excessive load, as this can damage the bore or alter alignment. Verify collar seating against the fixture surface after installation to confirm proper depth.
