Cam point screws and levers from J.W. Winco
January 5, 2012 – J.W. Winco Canada now offers series GN 418 cam point screws and GN 418.1 cam point levers in metric sizes.
These maintenance-free clamping elements are designed for a wide variety of uses and applications, including clamping flat or round workpieces, centric clamping on bore holes, and multiple clamping in tight spaces.
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 the same in every angular position. The force components 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 screw by a serration that allows for selecting the clamping position and adjusting the lever. Both the screw and the cam are case-hardened and burnished.
Right- and left-hand thread types are available.
