Gibraltar 49128G Slip Fit Round Straight Locating Pin

Product Description

The GIBRALTAR 49128G is a slip fit round straight locating pin used to accurately position and align workpieces or fixtures in machining, tooling, and assembly setups. Machined from low carbon steel, this pin features a 0.5293-inch nose diameter, 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 +0.0000-inch tolerance on the nose diameter ensures repeatable slip fit engagement without forced insertion. Machinists, toolmakers, and fixture builders install this type of pin during jig and fixture fabrication or machine setup.

This locating pin is suited for use in drill jigs, machining fixtures, assembly fixtures, and production tooling wherever precise, repeatable part location is required. The slip fit design allows easy insertion and removal by hand or with minimal tooling, making it practical for setups that require frequent workpiece changes. The non-relieved body and straight profile make it appropriate for standard through-hole locating applications in both light manufacturing and precision machining environments.

Key Features

• Slip fit nose diameter of 0.5293 inches with +0.0000-inch tolerance for precise, repeatable location
• Low carbon steel construction provides adequate hardness and machinability for tooling applications
• 1-1/8-inch collar diameter retains the pin positively against the fixture plate
• Non-relieved straight body for standard through-hole locating use
• Compact overall length of 1-15/16 inches suits tight fixture clearances
• 3/16-inch chamfer length on nose aids alignment during workpiece loading

Compatibility

Designed as a standard slip fit locating pin for use in drill jigs, machining fixtures, and assembly tooling requiring a 0.5293-inch nose diameter slip fit hole.

Installation Notes

Locating pins of this type are installed by toolmakers or machinists during fixture assembly. Ensure the receiving bore in the fixture plate is clean, properly sized, and free of burrs before pressing or sliding the pin into position. No power-down or lockout procedure is required for fixture assembly, but standard shop safety practices apply when working with precision tooling components. Do not force the pin into an undersized bore, as this can alter the slip fit characteristics.
