Gibraltar 49111G Slip Fit Locating Pin 0.2808 in Nose

Product Description

The GIBRALTAR 49111G is a slip fit round straight locating pin designed for workholding and fixturing applications in manufacturing and machining environments. Machined from low carbon steel, this pin features a 0.2808-inch nose diameter with a slip fit tolerance of plus 0.0000 inches, allowing controlled, repeatable part registration without interference. The nose length measures 7/16 inches, the collar diameter is 5/8 inches, and the tail diameter is 5/16 inches. Overall length is 1-3/16 inches. Chamfer length is 3/32 inches. This pin is not relieved. Machinists, toolmakers, and fixture builders install this type of component during jig and fixture assembly or machine setup.

This locating pin is suited for precision workholding fixtures, jigs, and tooling plates in light to medium machining operations. The slip fit design allows easy insertion and removal of workpieces while maintaining accurate positional registration. Applications include CNC machining centers, drill jigs, inspection fixtures, and assembly tooling where repeatable part location is required. The low carbon steel construction provides adequate strength for general-purpose fixturing in both job shop and production environments.

Installation Notes

Toolmakers and fixture builders typically install locating pins using a hand press or arbor press. Ensure the receiving bore in the fixture is clean and free of burrs before installation. Verify fit classification against workpiece tolerances before final assembly. Always follow shop safety procedures and de-energize any associated machinery before servicing or replacing fixture components.
