Product Information

Steel and Stainless Steel Press-Thru™ Ball Plunger with Delrin Ball

The new Press-Thru™ Ball Plunger has the same body dimensions, spring pressure and materials as the Press Fit Ball Plungers. It will not have the flange on the ball end. This will allow for insertion into the work piece from the top or bottom, front or back. Simply press the body so the plunger end is flush with the surface. Without the flange, these plungers may be used where less clearance is available. They are made oversized to secure firmly into the hole.

Steel bodies are made of 12L14 material with a black oxide finish.

Stainless bodies are made of 303 material.

White end represents light pressure. Yellow end represents heavy pressure.
