Product Information

Steel and Stainless Steel Press-Thru™ Spring Plungers with Heavy Pressure

The new Northwestern Press Spring Plunger has the same body dimensions, spring pressure and materials as the Press Fit Spring Plungers. It will not have the flange on the nose 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.

All stainless steel parts are made of 303 material.

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