Hex-edge fixture clamps have a six-sided head to apply clamping pressure to the side of a workpiece when access to the top of the workpiece is required. Clamps have an offset screw that pushes the clamp against the workpiece edge when tightened.

Knife-edge fixture clamps have serrated rows of sharp ridges to grip edges on rough-cut stock or irregular surfaces. Clamps have an offset screw that pushes the clamp against the workpiece edge when tightened.

Adjustable fixture clamps have six sides that are each a different distance from the center screw to provide a variety of clamping options. The clamp is rotated when the workpiece size changes.

Machinable fixture clamps can be cut, shaped, or machined to conform to irregular workpieces when secure clamping is required. Clamps have an offset screw that pushes the clamp against the workpiece edge when tightened.
