Threaded Spring-Loaded Guide Pins

Threading makes these guide pins easier to remove and replace than press fit, so they're useful for high-wear applications. A sealed top prevents debris from getting inside and making them seize up. As the workpiece pushes against the pin head in one direction, the internal spring pushes back to hold it in place for clamping.

Threaded Hole Location Gauges

Find the true center of threaded holes to precisely align and measure parts. Once you thread these gauges into a hole, their cylinder sticks out as a reliable reference point. They’re often used with a coordinate measuring machine (CMM) to pinpoint the coordinates of the cylinder’s exact center. You can then use those coordinates to measure distances between points or reference them for error-free assembly. Even without a CMM, you can use these gauges with a micrometer to measure accurate center-to-center distances.
