Gibraltar 49105G Slip Fit Round Straight Locating Pin

Product Description

The GIBRALTAR 49105G is a slip fit round straight locating pin manufactured from low carbon steel. It is used in fixturing, jigs, and workholding applications to accurately position and align workpieces or components during machining, assembly, or inspection operations. The pin features a 0.187-inch nose diameter and a 7/16-inch nose length, with a 5/8-inch collar diameter that seats against the fixture plate to control insertion depth. Overall length is 1-3/16 inches. The +0.0000-inch tolerance on the nose diameter ensures a controlled slip fit, allowing repeatable part location without binding. Machinists and fixture builders install this type of pin in production and toolroom environments.

This locating pin is suited for use in drill jigs, milling fixtures, welding fixtures, and assembly nests where consistent, repeatable part registration is required. The straight, non-relieved body design provides full contact along the tail diameter for stable seating in the fixture body. With a 5/16-inch tail diameter, it presses or slides into a standard drilled and reamed receiver hole in a fixture plate. Typical applications are found in both manual and automated workholding setups across general metalworking and precision machining environments.

Compatibility

Designed as an OEM-style locating pin for use in standard fixturing and workholding applications requiring a slip fit round straight pin with a 0.187-inch nose diameter and 5/16-inch tail diameter.

Installation Notes

Locating pins of this type are installed by toolmakers and fixture builders. The receiver hole in the fixture plate should be drilled and reamed to the appropriate tolerance to achieve the intended slip fit. Ensure the fixture is secured and not under load before installing or removing pins. Do not force the pin into an undersized hole, as this can damage the nose geometry and compromise location accuracy.
