J.W. Winco, Inc. now offers series GN 418 Cam Point Screws and GN 418.1 Cam Point Levers in metric sizes. These RoHS compliant components are maintenance-free clamping elements designed for a wide variety of different uses and applications, including clamping flat or round workpieces, centric clamping in bore holes, and multiple clamping in tight spaces. They are stable, compact, and easy to use.
The mode of function is identical for both: The screw head of the cam point screw is fitted with two cams: a radial clamping cam (with additional 30° chamfer) and an axial draw-down cam. The self-locking cam ensures that the clamping force is of the same magnitude in every angular position. The force components acting at the clamping point generate friction and a draw-down effect, which presses the workpiece against a fixed-end stop. The thread and the 30° chamfer (if fitted) generate an additional draw-down effect.
Cam point screws are fitted with a hexagon head socket. The steel is case-hardened, zinc-plated and blue passivated. Cam point levers have a handle (with black plastic ball knob) connected to the cam point screw with a serration, allowing the suitable clamping position to be selected and the lever to be adjusted. Both the screw and the cam are case-hardened and burnished. Both right-hand and left-hand thread types are available.
