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.

Steel and Stainless Steel Metric Knurled Head Plungers - Locking
Product Information

Steel and Stainless Steel Metric Knurled Head Plungers - Locking

All stainless parts are 303 material.

Steel parts are 12L14 zinc plated.

Noses are 11L41, heat treated.

Improved design allows plunger nose to be locked in a fully retracted position. Plunger nose has a chamfered end to assure easy alignment. Full pressures are the force pounds needed to move the nose the distance shown in "C" column.

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.

Zinc Plated Steel or Stainless Steel

Plunger can be withdrawn completely into the body and locked in a fully retracted position.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.

Available with or without locking element.
