Steel Body Short Spring Plungers with Extended Travel
Product Information

Steel Body Short Spring Plungers with Extended Travel

Bodies are 12L14 steel with a black oxide finish.

Noses are 12L14 black oxide steel or brown delrin.

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.

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