Gibraltar 677006-G Bullet Straight Locating Pin

Product Description

The GIBRALTAR 677006-G is a bullet-style straight locating pin machined from steel, designed to accurately position workpieces in fixtures, jigs, and tooling setups. The pin features a 0.2499-inch nose diameter with a bullet-shaped nose profile and a 7/32-inch nose length for guided entry into mating holes. A 9/16-inch collar diameter provides a positive seating surface, while the 0.4078-inch tail diameter anchors the pin firmly in the fixture body. Overall length is 21/32 inches. The relieved design reduces contact area for consistent, repeatable positioning. Machinists and toolmakers install this pin in precision workholding applications where accurate part location is critical.

This locating pin is suited for use in production fixtures, inspection jigs, and machining setups across manufacturing environments. The bullet nose eases part loading and reduces wear during repeated cycles, making it appropriate for moderate-to-high-volume operations. The relieved body minimizes the risk of hydraulic lock in blind holes and helps maintain cleanliness in the bore. Typical applications include CNC machining centers, assembly fixtures, and quality control gages where consistent datum location is required.

Key Features

• Bullet nose profile guides workpieces smoothly onto the pin during loading
• Relieved body reduces hydraulic lock and simplifies cleaning in blind-hole installations
• Steel construction provides durability in repeated-use fixture applications
• 0.2499-inch nose diameter with +0.0000-inch tolerance for precise fit
• 9/16-inch collar diameter seats firmly against the fixture plate surface
• Compact 21/32-inch overall length suits low-profile fixture designs

Compatibility

Designed as an OEM-style locating pin for use in standard workholding fixtures, jigs, and tooling plates requiring a bullet-nose straight pin with a 0.2499-inch nose diameter and 0.4078-inch tail diameter.

Installation Notes

Installation is typically performed by a machinist or toolmaker using a press or mallet to seat the tail diameter into the fixture body bore. Ensure the receiving bore is clean and sized to the appropriate interference or slip fit before pressing the pin into place. Do not strike the nose directly, as this may damage the precision-ground surface. Verify seating depth against the collar before loading workpieces.
