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.

Hex Drive "Short" Steel Spring Plungers with Light Spring Pressures
Product Information

Hex Drive "Short" Steel Spring Plungers with Light Spring Pressures

Delrin® nose prevent marring of aluminum, brass or other soft materials.

Hex Drive Plungers use a positive drive for insertion and removal.

Plungers may be ordered with or without the locking element. Plungers without locking element are the same price, but are considered "specials" and cannot be returned. We recommend using without the locking element for applications in aluminum.

The Nylon locking element holds the plunger body securely in place witout the need for lock nuts or other devices. We recommend a 90° countersink 1/32" larger than the major diameter of the mating thread to prevent damaging the element.

End pressures are given in pounds. Full pressures are the force pounds needed to move the nose to the distance show in "C" column.

To prevent possible spring damage, use of a Northwestern Wrench is recommended when installing from plunger end.
