Gibraltar 677021-G Bullet Straight Locating Pin

Product Description

The GIBRALTAR 677021-G is a bullet straight locating pin machined from steel and designed to precisely position workpieces in fixtures, jigs, and tooling setups. The bullet-shaped nose measures 0.4998 inches in diameter and 13/32 inches in length, guiding parts onto the pin with controlled entry before seating against the 7/8 inch collar. The tail diameter is 0.7518 inches with a 1/2 inch tail length and an overall length of 31/32 inches. A relieved body reduces contact surface for easier insertion and removal in repetitive production environments. Tolerance is held at +0.0000 inches for consistent, repeatable location accuracy.

This locating pin is suited for use in machining fixtures, assembly jigs, welding positioners, and quality inspection tooling across both light and heavy manufacturing environments. It is typically installed by toolmakers, fixture builders, and machine shop technicians working in precision fabrication or production assembly. The relieved design is particularly useful in applications where quick part loading and unloading is required to maintain cycle time efficiency.

Key Features

• Bullet nose profile guides parts onto the pin smoothly during loading
• Relieved body reduces friction and wear during repeated insertions
• 0.4998 inch nose diameter for precise workpiece location
• Steel construction provides durability in production tooling applications
• +0.0000 inch tolerance ensures consistent positional accuracy
• Compact overall length of 31/32 inches for use in space-constrained fixtures

Compatibility

Designed as a standard OEM-style replacement or new-build component for use in precision machining fixtures, assembly jigs, and locating tooling applications requiring a bullet-style straight locating pin.

Installation Notes

Installation is typically performed by toolmakers or fixture technicians using a press fit or slip fit method depending on the tolerance of the receiving bore. Ensure the mating bore is clean and free of debris before pressing or inserting the pin. Always verify that the pin is fully seated and the collar is flush against the fixture plate before placing the assembly into service. Follow applicable shop safety procedures when using press equipment.
