Clamping Pins for Insertion in Pin Holes

Clamping pins that are used for insertion in pin holes are designed for convenient top-down installation when underside access is limited. Instead of being bolted from beneath, these pins can be dropped into a precise bore on the workpiece or fixture, then secured in place, allowing fast addition or removal of locating pins. Many of these pins omit the usual centering collar so they sit flush in the hole and can be easily inserted or swapped, yet they still lock firmly once the quick-change module clamps onto them. This design lets you retrofit existing fixtures or thick plates with zero-point clamping points on the fly, maintaining the same reliable clamping accuracy and strength while simplifying your setup process.
