Gibraltar 677130-G Bullet Straight Locating Pin Steel

Product Description

The GIBRALTAR 677130-G is a bullet straight locating pin used to precisely position and align workpieces, fixtures, or tooling components in machining, fabrication, and assembly setups. Machined from steel, this pin features a 0.2499-inch nose diameter with a bullet-shaped nose profile that allows for smooth, guided entry into mating holes. The overall length is 0.907 inches, and the pin carries a tolerance of +0.0000 inches, making it suitable for applications that demand consistent, repeatable alignment. Installation is straightforward and the pin is intended for use by machinists, toolmakers, and fixture builders working in production or job-shop environments.

This locating pin is designed for use in jigs, fixtures, and workholding setups where accurate part positioning is critical. The bullet nose provides lead-in guidance during placement, reducing the risk of misalignment. The collar diameter of 0.28 inches and tail diameter of 0.2516 inches allow it to seat securely within standard locating pin configurations. Liner compatibility is noted for UDB-635180. The pin is sold individually and is well-suited to both light production runs and precision prototype work.
