Clamping elements 680

Universal clamping system for clamping from all workpiece shapes, whether square, diagonal, concave or convex. Design: The special feature of this clamping device is the steel screw (strength 10.9) with the eccentric head. The eccentric tappet gives the clamping motion a very high clamping force. A hexagonal brass disc serves as clamping piece.

Application: All workpieces with the most varied shapes can be clamped with retaining studs and 1 or 2 clamping screws. The small installation height enables machining the workpiece surface without problems. Thus, the position of the clamping jaws does not have to be taken into account in CNC programming work. In addition, the compact dimensions allow space-saving multiple clamping. The tension clamps can also be used as dog.

Eccentric tension clamp

Application: For screwing-in and clamping onto jigs.
