Steel Ball Nose Spring Plungers

by Tony Losey — last modified 2009-09-10 16:08
Ball Nose Spring Plungers Ball Nose Spring Plungers
  • Bodies Steel or Stainless Steel
  • All Noses are Stainless Steel or Delrin
  • All Plungers are Standard with Nylok Element
  • Slotted Drive

The Nylok 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 larges than the major diameter of the mating thread to prevent damaging the element and reducing the locking torque.

To Order A Part Without the Locking Element, Add "P" to the Part Number. Example 56001P
