The spring is assembled from the top so that there is no need for a set screw. SOLID DRIVE Plungers do not have a set screw which can loosen or separate from the plunger body. The advantage is no lost springs, no need for “easy-out” tools. When adjusting SOLID DRIVE, you can be sure the plunger body is turning and not a set screw. • Material: Body – Low Carbon Steel, Black Oxide or 303-Stainless Steel Tip – Delrin • Thread: 2A-UNC • Available in FixtureProTM Design Software • Conforms to TCMA dimensional standards NOTE: For easy insertion of Spring Plungers with locking elements, the tapped hole should be countersunk at least .030-.045" (0.76-1.14mm) larger than the major diameter of the plunger.
