klemblokker

Klemblokker is a Dutch term that generally refers to a clamping block used in jigs, fixtures, and workholding systems to hold a workpiece securely during machining, assembly, or measurement. The concept emphasizes repeatable positioning and stable restraint, often as part of modular fixturing.

In design, a klemblokker is typically a small, rigid block made from steel, stainless steel, or aluminum. It usually includes a flat or machined clamping face and one or more holes or threads to accept bolts, pins, or set screws. Some variants incorporate a built-in clamping mechanism, such as a screw or cam, that applies pressure directly to a workpiece when tightened. Blocks may be flat, stepped, or shaped to fit alongside standard T-slots or other fixture components, enabling flexible arrangement in a fixture layout.

Common applications include securing workpieces on milling machines, drill presses, and CNC setups, as well as in assembly lines and quality control stations. They are often used in conjunction with other clamping elements—such as toggle clamps, magnetic clamps, or vise jaws—to achieve precise, repeatable fixturing with minimal movement.

Materials and standards vary by manufacturer and intended use, but durability and dimensional accuracy are key considerations. Klemblokkers are part of broader fixturing systems intended to improve repeatability, reduce setup time, and enhance machining accuracy.
