Product Information
Metric Short Spring Plungers with Light Spring Pressures
Steel noses are case hardened for wear resistance without brittleness.
Steel bodies are 12L14 steel with a black oxide finish.
The 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.
Plungers may be ordered with or without the locking element. Plungers without the element are the same price, but are considered "specials" and cannot be returned. We recommend using without the locking element for applications in aluminum.
To prevent possible spring damage, use of a Northwestern Wrench is recommended when installing from plunger end.
