Abstract

A hold-down utilizing a round, interchangeable post having annular barb-like ridges or projections that engage a workbench top through round holes that may be located at substantially any desired positions in the bench top. The post threads into a hold-down body having, on one side of the post, a yoke within which a gooseneck-shaped hold-down arm pivots on a pin received in yoke arms or forks and, on the other side of the post, a screw pressure point and T-shaped slot for receiving the head of a clamping adjustment screw that is journaled through one end of the clamping arm. The other end of the clamping arm terminates in a foot with a rounded pad for exerting pressure against a workpiece.
