Tapered Index Plungers
Tapered Index PlungersIndex plungers are precision, heavy-duty assemblies with a retractable spring-loaded plunger and a matching locating bushing. Tapered Index Plungers feature a 15° 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 180°. Cam surfaces are hardened steel. Made in USA.
The flange-mount configuration provides orientation by fastening the flange with two socket-head cap screws. Flange mounting is designed for installations where a cross hole for a whistle-notch set screw is not practical.
