locating pins and bushings

Cone Pin Locators

These locating pins are designed for the quick assembly of two fixture components by compensating for significant misalignment between mating parts. They are ideal for applications requiring rapid positioning and moderate alignment accuracy. The pin design helps prevent fixture misalignment during assembly, improving repeatability, reducing setup time, and ensuring consistent component positioning. Suitable for jigs, fixtures, and tooling applications where fast and reliable location is required.
