Gibraltar 677005-G Bullet Straight Locating Pin Steel

Product Description

The GIBRALTAR 677005-G is a bullet-style straight locating pin machined from steel, used to precisely position workpieces or fixtures during machining, assembly, and inspection operations. The pin features a 0.2499-inch nose diameter with a bullet-nosed profile that guides parts smoothly into position without damaging bore edges. The collar diameter measures 9/16 inches, and the overall assembly length (OAL) is 21/32 inches. A zero-inch tolerance designation (+0.0000 inches) ensures controlled fit for applications requiring repeatable, accurate part location. This pin is installed by machinists, toolmakers, and fixture builders working in precision manufacturing environments.

The 677005-G is suited for use in jigs, fixtures, and workholding setups across general machining, fabrication, and assembly applications. The bullet nose geometry allows for easy part engagement even when minor misalignment is present, making it practical for production environments where cycle time matters. The steel construction handles the mechanical demands of repeated loading and unloading cycles in both light and moderate-duty fixture applications.

Key Features

• Bullet nose profile guides workpieces into position smoothly without gouging bore surfaces
• Steel construction provides durability for repeated use in production fixtures
• 0.2499-inch nose diameter with +0.0000-inch tolerance for controlled, repeatable fitment
• Non-relieved shank design maintains full contact along the tail diameter for stable seating
• Compact OAL of 21/32 inches suits confined fixture layouts
• Single-piece unit with no assembly required

Compatibility

Designed as a standard OEM-style locating pin for use in precision jigs, fixtures, and workholding assemblies requiring a bullet-nose straight pin with a 0.2499-inch nose diameter and 9/16-inch collar diameter.

Installation Notes

Locating pins of this type are installed by toolmakers or fixture technicians and typically pressed or slip-fit into a hardened or reamed receiver hole in a fixture plate. Ensure the receiving bore is clean and free of burrs before installation to preserve the pin's tolerance fit. Powering down or locking out any associated machinery before servicing fixtures is standard practice per applicable safety protocols. Do not hammer directly on the nose of the pin, as this can deform the bullet profile and compromise location accuracy.
