Press-Thru™ Spring and Ball Plungers

Our line of Press-Thru™ spring and ball plungers have the same dimensions, spring pressures, and materials as our standard press fit product line. They are designed without the flange on the nose end to allow for the insertion of the plunger from top or bottom, front or back. Simply press the body through the hole until the plunger is flush with the surface. The body is slightly over sized to fit firmly into the hole. Please contact us for a free sample, or if you need any technical information.

Threaded Adapter-Locking
Product Information

Threaded Adapter* - Locking

The new threaded adapter is designed to accept any internally threaded knob or handle.

Available with or without locking element.

Material is 12L14 steel or 303 stainless.

The nylon locking element holds the plunger body securely in place without the need for lock nuts or other devices. We recommend a 90 degree countersink 1/32" larger than the major diameter of the mating thread to prevent damaging the element.

Plunger can be withdrawn completely into the body and locked in a fully retracted position. To engage the plunger, simply turn to line up with slot in body.
