Gibraltar 49115G Slip Fit Round Straight Locating Pin

Product Description

The GIBRALTAR 49115G is a slip-fit round straight locating pin used in workholding, fixturing, and precision assembly applications. Machined from low carbon steel, this pin features a 0.3271-inch nose diameter with a slip-fit nose shape, allowing repeatable part registration without press-fit interference. The overall length is 1.5 inches, with a 0.5-inch nose length, a 0.5-inch tail diameter, and a 0.875-inch collar diameter. The pin is not relieved and carries a tolerance of plus 0.0000 inches, making it suitable for close-clearance locating work on jigs, fixtures, and machining pallets. Machinists, toolmakers, and fixture builders install this type of component during workholding setup.

This locating pin is suited for use in manufacturing environments where accurate and repeatable part positioning is required. Typical applications include fixture plates, drill jigs, assembly nests, and production tooling. The slip-fit design allows parts to be seated and removed without heavy force, reducing wear on both the pin and the workpiece locating hole. The 0.125-inch chamfer length at the nose aids part entry during loading. This pin is appropriate for light to medium duty fixturing tasks in job shops, production facilities, and tool rooms.

Compatibility

Designed as an OEM-style replacement or direct-use locating pin for standard fixture plates and workholding assemblies requiring a slip-fit round straight pin with a 0.3271-inch nose diameter.

Installation Notes

Locating pins of this type are installed by toolmakers and fixture technicians using standard hand tools or a light mallet where needed. Ensure the receiving hole in the fixture plate is clean and free of burrs before installation. De-energize and lock out any associated machine or fixture before servicing or replacing locating pins. Verify hole diameter tolerance in the mating fixture matches the slip-fit specification to maintain proper clearance and location accuracy.
