Gibraltar 49305G Diamond Locating Pin 0.187in Nose

Product Description

The GIBRALTAR 49305G is a slip-fit diamond straight locating pin used to accurately position and register workpieces in fixtures, jigs, and tooling setups. The diamond nose profile allows the pin to engage a second locating hole without over-constraining the part, making it the correct choice when two round locating pins would otherwise bind. Machined from low carbon steel, the 49305G features a 0.187-inch nose diameter, a 7/16-inch nose length, and a 5/8-inch collar diameter. The tail diameter is 5/16 inch and the overall length is 1-3/16 inches. This pin is installed by toolmakers, fixture builders, and machinists in production and job-shop environments.

The 49305G is suited for use in drill jigs, weld fixtures, assembly fixtures, and inspection tooling where repeatable part location is required. The slip-fit tolerance (+0.0000 inches) and relieved body design make it appropriate for applications requiring controlled engagement without press-fit installation. It is a direct drop-in component in standard locating pin bores sized for the 5/8-inch collar and 5/16-inch tail.

Key Features

• Diamond nose profile eliminates over-constraint when used alongside a round locating pin
• Slip-fit tolerance (+0.0000 inches) for controlled, repeatable engagement
• Relieved body reduces contact area and eases installation and removal
• 0.187-inch nose diameter with 7/16-inch nose length for precise workpiece registration
• Low carbon steel construction provides adequate strength for standard fixture applications
• 1/16-inch chamfer length aids pin entry into locating holes

Compatibility

Designed as an OEM-style replacement or standard component for tooling fixtures requiring a slip-fit diamond locating pin with a 5/8-inch collar diameter and 5/16-inch tail diameter.

Installation Notes

Installation is performed by toolmakers or machinists during fixture build or maintenance. Power down and lock out any associated machinery before servicing a fixture containing this pin. The slip-fit design allows hand or light mallet installation into a properly sized bore; do not force or press the pin into an undersized hole. Verify bore cleanliness and check for burrs before seating the pin to maintain location accuracy.
