J.W. Winco, Inc. Knobs Will Position, Secure and Clamp

NEW BERLIN, WI - J.W. Winco, Inc., a leading supplier of standard industrial machine components, announced it now offers series GN 7336.7 Clamping Knobs with Indexing Plunger as well as GN 7366.8, a version with safety function.

These RoHS-compliant knobs are used for positioning, securing and clamping adjusting elements simultaneously. The axial movement of the handle (pulling) pulls the indexing plunger from the engaged position against the spring force, with the knob meanwhile remaining connected with form-lock to the clamping screw via a hexagonal element. This design permits both clamping and releasing. The design of the GN 7336.8 ensures that the indexing plunger cannot be pulled from the indexing bore by turning the knurled knob, but only by deliberately pulling the handle (safety function).

The body of the knurled knob is glass fiber reinforced plastic with a black matte finish. The threaded body is zinc plated, blue passivated steel. The cover cap is glass fiber reinforced plastic with a light gray matte finish. The plunger pin is nitrided and blackened steel. These clamping knobs are offered in a range of metric sizes.
