Gibraltar 677011-G Bullet Straight Locating Pin Steel

Product Description

The GIBRALTAR 677011-G is a bullet-nose straight locating pin designed for precision fixturing and workholding applications in machining and tooling setups. Machined from steel, this relieved pin features a 0.3124-inch nose diameter and a 0.5017-inch tail diameter, with a 9/32-inch nose length and a 3/8-inch tail length for a total overall length of 23/32 inches. The bullet-shaped nose eases part location and loading while the relieved body reduces hydraulic lock and allows for faster fixture cycling. Machinists, toolmakers, and fixture builders are the primary installers of this component.

This locating pin is used in jigs, fixtures, and workholding plates where repeatable part location is required. It is suited for both light-production and high-cycle environments where quick part loading and unloading is essential. The relieved design allows trapped fluids to escape during press-in or part-seating operations, making it practical for wet-machining and high-volume fixture setups. The 5/8-inch collar diameter provides a positive stop against the fixture plate surface during installation.

Key Features

• Bullet-nose geometry eases part loading and reduces locating errors during fixture cycling
• Relieved body design prevents hydraulic lock and allows fluid relief in wet-machining environments
• 0.3124-inch nose diameter with a close +0.0000-inch tolerance for repeatable part location
• 5/8-inch collar diameter provides a positive seating stop against the fixture plate
• Steel construction for durability in production machining and toolroom applications
• Compact 23/32-inch overall length suited for low-profile fixture designs

Compatibility

Designed as a standard OEM-style replacement or new-build component for steel jig and fixture assemblies requiring a bullet-nose straight locating pin with a 0.3124-inch nose diameter and 5/8-inch collar.

Installation Notes

Locating pins are typically pressed or hand-fitted into fixture plates by toolmakers or machining professionals. Ensure the receiving hole is clean and dimensionally verified before installation. Pressing should be performed with appropriate arbor press tooling to avoid damaging the nose geometry or altering pin alignment. Follow your facility or shop standard for interference fit and locating pin retention practices.
