Extended Travel Stubby Plungers – Stainless Steel

Extended Travel Stubby Plungers – Stainless Steel are compact spring plungers that provide the same travel as a standard plunger while using the same body size as a stubby plunger. Use for limited space applications including indexing, electrical contacts, part positioning and detents. Stainless steel construction provides wear and corrosion resistance. Available with a stainless steel nose or Delrin® nose in ANSI thread sizes 8-32 through 5/8-11 and metric M4 x 0.7 through M16 x 2.0 with thread lock options and end forces listed as initial and final values in the tables.

Specify by:

Thread standard and size (ANSI or metric)
Nose style (stainless steel or Delrin®)
End force requirement (initial and final)
Thread lock requirement
Mounting and stroke dimensions (A–D per table)
