Indexing 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 on Tapered Index Plungers makes alignment easier and eliminates any binding during retraction. Straight Index plungers providing for slightly greater positional accuracy are also offered in this catalog section. Browse the full line of Carr Lane Indexing Plungers below.
