Stubby Plungers – Stainless Steel

Stubby Plungers – Stainless Steel are compact spring plungers that provide greater travel than ball plungers and less travel than standard spring plungers for restricted space applications. Use for indexing, detents, electrical contacts and part positioning. Features include a case hardened plunger, wear and corrosion resistance, intermediate travel and screwdriver installation. Available in ANSI thread sizes 8-32 through 5/8-11 and metric M4 x 0.7 through M16 x 2.0 with standard or light end forces and optional thread lock.

Specify by:

Thread standard and size (ANSI or metric)
End force requirement (standard or light)
Thread lock requirement
Mounting and stroke dimensions (A–D per table)
