Gibraltar 49135G Slip Fit Round Straight Locating Pin

Product Description

The GIBRALTAR 49135G is a slip fit round straight locating pin used in workholding and fixturing applications across machining, fabrication, and assembly operations. Machined from low carbon steel, this pin features a 0.748 inch nose diameter with an 11/16 inch nose length and a 1-1/8 inch collar diameter. The tail diameter measures 3/4 inch, and the overall length is 1-15/16 inches. A 3/16 inch chamfer length aids guided entry into mating holes. The nose profile is non-relieved and held to a +0.0000 inch tolerance, making it suitable for precision locating tasks. Toolmakers, fixture builders, and CNC setup technicians are the typical installers.

This locating pin is intended for use in jigs, fixtures, and workholding plates where repeatable part location is required. It is suited to light-duty slip fit applications in both manual and semi-automated machining environments. The collar provides a positive stop against the fixture plate surface, controlling insertion depth without additional hardware. It is commonly found in job shops, production machining cells, and assembly fixtures handling metal or composite workpieces.

Key Features

• Slip fit nose profile allows smooth insertion and repeatable part location
• Low carbon steel construction provides adequate hardness for fixture-grade applications
• Collar diameter of 1-1/8 inches acts as a built-in depth stop against the fixture plate
• 3/16 inch chamfer length on nose aids alignment during pin entry
• Non-relieved nose geometry maintains full contact along the locating surface
• +0.0000 inch tolerance supports consistent positional accuracy

Compatibility

Designed as a standard slip fit locating pin for use in tooling plates, jig bodies, and fixture bases that accept a 3/4 inch tail diameter with a 1-1/8 inch collar counterbore.

Installation Notes

Installation is performed by toolmakers or fixture technicians using standard hand tools. The receiving fixture plate should be machined to the appropriate clearance hole and counterbore dimensions before installation. Power down or lock out any associated machine or press before installing or removing locating pins in active fixtures. Do not force the pin into an undersized hole, as this can damage the nose geometry and compromise locating accuracy.
