J.W. Winco Inc. offers series GN 920.1 Wedge Clamps in metric sizes. Clamping with these RoHS-compliant wedge clamps is achieved via the socket head cap screw and the clamp wedge, which function by moving both jaws outward. When the screw is loosened, the clamp wedge returns to its original position via an internal return spring, which in turn, loosens the tension.
The wedge clamp is blackened steel with wedge surfaces hardened. The socket head cap screw is DIN 7984, black oxide steel grade 10.9. Tensile strength of socket head cap screw is 1000 N/mm2. Four types are offered: with smooth clamping jaws, with serrated clamping jaws, with prism-shaped jaws, and with two mounting threads for attachment jaws.
Wedge clamps are ideal for multiple clamping operations, but can also be used for clamping individual work pieces. The long hole in the clamp wedge serves to compensate for tolerances in the work piece.
