The new Northwestern Press Fit Spring Plunger uses the same body dimensions as our Press Fit Ball Plunger. Northwestern has added these plungers to handle your longer travel needs with a press fit body.
Steel bodies are made of 12L14 material with a black oxide finish.
All stainless steel parts are made of 303 material. A stainless steel part will withstand higher working temperatures.
Press Fit Spring Plungers can be used when a threaded Spring Plunger is impractical or when threaded adjustments are not required for detent. Easy installation. Use in wood, soft plastic or aluminum applications.
