J.W. Winco, Inc. announced it now offers series GN 607.4 and 607.5 Indexing Plungers for Welding, with or without Rest Position. These metric sized, RoHS compliant indexing plungers are especially designed for welded mounting, especially for use with steel square tubing.
The body is blackened steel, plunger hardened, and features a shoulder for easy positioning. The knob is matte black technopolymer plastic (Polyamide PA), not removable. The knob has a molded-in indexing pin and is supplied separately, to be driven in with a soft mallet after welding. The GN 607.4 series does not have a rest position, while the GN 607.5 series does. The rest position feature is used in applications where the indexing pin is temporarily not allowed to protrude. After pulling out, the knob is turned by 90° to its rest position and the pin no longer protrudes. An indexing notch prevents the disengaged knob from turning back accidentally or from shock impact.
