The Jergens Delrin Tip / Steel Spring Plunger, part number 30453, features a single-unit construction that eliminates the need for a set screw, enhancing reliability and preventing lost springs. The body is made from low carbon steel with a black oxide finish, while the tip is constructed from Delrin. This plunger conforms to TCMA dimensional standards and includes a patch-style locking element. It has a thread size of M8 x 1.25 and provides an initial force of 1.35 kg, with a final force of 6.75 kg. The hex drive at the rear facilitates easy insertion. For optimal performance, the tapped hole should be countersunk at least 0.030-0.045 inches larger than the major diameter of the plunger. Special materials and sizes can be requested.
Jergens Spring Plungers, unlike conventional spring plungers, are machined in one piece. The spring is assembled from the top so that there is no need for a set screw. Our Spring Plungers do not have a set screw that can loosen or separate from the plunger body. The advantage is no lost springs and no need for “easy-out” tools. When adjusting Solid Drive, you can be sure the plunger body is turning and not a set screw.
