BTM Pin Locator Clamps

Locate & clamp through holes in a workpiece. Locking & Non-Locking Models are available.

A BTM Pin Clamp locates and holds a part inexpensively and accurately.

» Inexpensively because it combines a locating pin with a power clamp or gripper in one device that is lightweight and easy to mount.


» Accurately because it engages datum oriented holes already in the part.
