Steel Short Spring Plungers with Heavy Spring Pressures
Product Information

Steel Short Spring Plungers with Heavy Spring Pressures

Steel noses are case hardened for wear resistance without brittleness.

Bodies are 12L14 steel with a black oxide finish.

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.
