Metric Spring Plungers — Standard Lengths

Metric Spring Plunger

Locking Element
Spring Plunger drawing

Steel or Delrin® Nose
Heavy or Light Spring Pressures

Bodies are steel with a zinc plate finish OR Stainless Steel

End pressures are given in kilograms or newtons (for stainless steel). Full pressures are the force kilograms needed to move the nose the distance shown in "C" columns.

The nylon locking element holds the plunger body securely in place without 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.

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

All dimensions in millimeters

*Conform to TCMAI/NIJFCM standards
