J.W. Winco, Inc. announced it now offers GN 817.8 metric size, steel indexing plungers with removable pin lock-out or non lock-out type.
The RoHS compliant GN 817.8 indexing plungers are designed so that special versions of the indexing pins can be made economically in smaller unit quantities. If required, the indexing pins can be machined or made by the user. They are assembled with a countersunk screw and can therefore be assembled several times. All parts are supplied individually as a disassembled set.
One version of the indexing plungers is used for applications where the plunger has to stay in its retracted position. To achieve this, the knob is rotated by 90° degrees after being retracted, as a notch keeps the plunger in this position. The maximum heat resistance of the matte black technopolymer nylon plastic hand knob, which is not removable, is 110°C (230°F).
The threaded body and lock nut are steel with a black oxide finish, while the plunger pin and countersunk screw are stainless steel.
