Gibraltar 49129G Slip Fit Round Straight Locating Pin

Product Description

The GIBRALTAR 49129G is a slip fit round straight locating pin used to precisely position and register workpieces or fixtures during machining, assembly, or inspection operations. The pin features a 0.5605 inch nose diameter, a 0.6875 inch (11/16 inch) nose length, and a 1.125 inch (1-1/8 inch) collar diameter that seats against the mounting surface to control insertion depth. The tail diameter is 0.75 inches (3/4 inch) and the overall length (OAL) is 1.9375 inches (1-15/16 inches). Constructed from low-carbon steel, this pin is installed by machinists, toolmakers, and fixture builders who require repeatable part location with a clearance fit.

This locating pin is suited for use in jigs, fixtures, and tooling plates in light-duty machining and assembly environments. The slip fit design allows the workpiece or mating component to be placed and removed without press force, making it appropriate for production setups where frequent loading and unloading occurs. The non-relieved round nose and straight body provide full contact along the bore, supporting accurate positional repeatability in both manual and semi-automated assembly stations.

Key Features

• Slip fit round nose for easy workpiece loading and removal without press force
• 0.5605 inch nose diameter with zero positive tolerance for controlled clearance fit
• 1.125 inch collar diameter provides a positive seat against the mounting surface
• Non-relieved body style for full bore contact and maximum positional accuracy
• Low-carbon steel construction offers adequate strength for light- to medium-duty fixture applications

Compatibility

Designed as an OEM-style replacement or direct-fit locating pin for jigs, fixtures, and tooling plates requiring a slip fit round straight pin with a 0.5605 inch nose diameter and 3/4 inch tail diameter.

Installation Notes

Installation is typically performed by machinists or toolmakers using standard hand tools. Ensure the mating bore is clean and free of chips or burrs before inserting the pin. Verify the collar seats flush and fully against the fixture plate surface before use. No press or thermal fitting methods are required for slip fit applications.
