Gibraltar 49101G Slip Fit Round Locating Pin 0.1245in

Product Description

The GIBRALTAR 49101G is a slip-fit round straight locating pin used to precisely position workpieces, fixtures, and tooling components during machining and assembly operations. Machined from low carbon steel, this pin features a 0.1245-inch nose diameter with a slip-fit tolerance of +0.0000 inches, ensuring accurate and repeatable part location without forced insertion. The nose length measures 7/16 inches, the tail diameter is 5/16 inches, and the overall length (OAL) is 1-3/16 inches. The collar diameter is 5/8 inches. Toolmakers, fixture builders, and CNC machinists install these pins in jigs, fixtures, and assembly plates where consistent part registration is required.

This locating pin is suited for use in machining jigs, weld fixtures, inspection fixtures, and production tooling in both job-shop and manufacturing environments. The slip-fit design allows the pin to seat into a mating hole without driving force, making it appropriate for applications requiring frequent workpiece loading and unloading. The non-relieved body style provides full contact along the pin shank for maximum lateral support. The 1/32-inch chamfer length on the nose aids in guiding the pin into the mating bore during installation.

Key Features

• Slip-fit tolerance of +0.0000 inches for precise, repeatable workpiece location
• Low carbon steel construction provides adequate strength for standard fixture and jig applications
• Non-relieved body style delivers full shank contact for lateral stability
• 0.1245-inch nose diameter with 7/16-inch nose length and 5/8-inch collar diameter
• 1/32-inch chamfer on nose for easy entry into mating bore
• Compact and lightweight at 0.03 pounds, suitable for close-tolerance fixture layouts

Compatibility

Designed as a standard slip-fit locating pin for use in machining jigs, assembly fixtures, and tooling plates where a 0.1245-inch nose diameter slip-fit round pin is specified.

Installation Notes

Installation is typically performed by toolmakers or fixture builders during jig and fixture assembly. The mating hole in the fixture plate should be machined to the appropriate slip-fit tolerance before inserting the pin. No press force should be applied, as this is a slip-fit design. Inspect the mating bore for burrs or contamination before seating the pin to avoid damage to the locating surfaces.
