Tapered Index Plungers x plungers are precision, heavy-duty assemblies with a retractable spring-loaded plunger and a matching locating bushing. Tapered Index Plungers feature a 15ยฐ taper on the plunger tip with a mating taper in the bushing. The taper makes alignment easier and also eliminates any binding during retraction Rotary-cam action completely retracts the plunger when the handle is rotated 180ยฐ. Cam surfaces are hardened steel. Made in USA.
The standard-mount configuration has a whistle notch on the Index Plunger for orientation with a setscrew.
Index plungers are manufactured with precision working tolerances and are designed for very light interference-fit installations to avoid binding of the mechanism. Setscrews with nylon tip inserts are recommended. Setscrews should firmly contact the whistle notch, but not exert significant force.
