Gibraltar 677016-G Bullet Straight Locating Pin

Product Description

The GIBRALTAR 677016-G is a bullet straight locating pin used to precisely position and register workpieces in jigs, fixtures, and tooling setups. Machined from steel, this pin features a bullet-shaped nose that guides workpieces smoothly onto the locating diameter without hang-up or damage. The relieved body reduces contact friction during loading and unloading. With a nose diameter of 0.3748 inches and a tail diameter of 0.6267 inches, the pin seats firmly through a drilled and reamed locating hole while the collar provides a positive stop against the fixture plate.

This locating pin is suited for production machining environments, assembly fixtures, and quality inspection tooling where repeatable part location is required. Machinists, toolmakers, and fixture builders install these pins in steel and aluminum tooling plates to achieve consistent datum control across multiple workpiece setups. The 0.3748-inch nose diameter, 5/16-inch nose length, 3/4-inch collar diameter, and 7/8-inch overall length make this pin appropriate for compact fixture designs with limited clearance.

Key Features

• Bullet nose profile guides workpieces onto the locating diameter smoothly
• Relieved body reduces drag during part loading and unloading
• Steel construction for durability in production tooling applications
• Collar diameter of 3/4 inches provides a positive seating surface against the fixture plate
• Tolerance of +0.0000 inches on nose diameter for precise fit
• Compact overall length of 7/8 inches suits space-constrained fixture layouts

Compatibility

Designed as a standard straight locating pin for use in machining jigs, assembly fixtures, and inspection tooling where a 0.3748-inch nose diameter locating hole is present.

Installation Notes

Locating pins of this type are installed by toolmakers and machinists during fixture fabrication or maintenance. The mating locating hole in the fixture plate should be drilled and reamed to match the pin nose diameter for proper fit. Press or hand-drive the pin into the tooling plate after ensuring the mounting surface is clean and free of burrs. Remove the fixture from any active machining cycle before replacing or adjusting locating pins.
