Hand Retractable Plungers — Knurled Head
Non-Locking

Knurled Head
Zinc Plated Steel or Stainless Steel

Knurled Head drawing

Used in machining applications as positioners, loading pins, indexing devices.

Available with or without locking element. To order without locking element, add a "P" to the end of the part number.

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.

Plunger can be withdrawn completely into the body and easily re-engaged.

Radiused Delrin® Nose. Click here for sizes.

All light pressure have an "L" stamped into the knurl.
