Standard Spring Plungers – Stainless Steel

Standard Spring Plungers – Stainless Steel are threaded spring loaded devices used for positioning, indexing, detent and latching functions where long travel and a large bearing surface are required. Stainless steel construction withstands high temperatures and provides maximum protection against rust and corrosion. Available in ANSI thread sizes 6-32 through 1-8 and metric M4 through M16 with heavy or light end forces and optional thread lock.

Specify by:

Thread standard and size (ANSI or metric)
Required travel
End force profile (heavy or light)
Thread lock requirement
