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 Ball Plungers with Delrin Ball
Product Information

Steel Ball Plungers with Delrin Ball

Steel bodies are 12L14 material with black oxide or zinc plate finish.

Bodies are color coded.

Plain is 303 stainless steel.

Silver is zinc plated steel - light pressures.

Black is black oxide steel - medium pressures.

Gold is gold chromate finish - heavy pressures.

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.

#6-40 and smaller have no slot in ball end
