Stubby Plungers

Steel

Stubby plungers offer greater travel than ball plungers and less travel than standard plungers. These compact spring plungers provide considerable plunger travel and high end forces which are ideal for restricted space applications.

Typical Uses

Limited space
Indexing
Electrical contacts
Part positioning
Locking
Detents

Special Features

Case hardened plunger
Wear & corrosion resistance
Compact size
Allows some side loading
Intermediate travel
Screwdriver installation
