200 New Solid Drive® Spring Plunger Items!


September 19, 2006—Jergens, Inc., one of the world’s largest manufacturers of standard tooling components, announces the addition of nearly 200 new items to their line of exclusive Jergens Solid Drive® Spring Plungers. Available in new sizes are stainless steel spring plungers, stainless steel ball plungers, and fine thread plungers.


The new configurations and sizes are in response to growing demand from key distribution partners and their customers. The line expansion ensures that distributors can depend on Jergens as their single source supplier of critical components when they need them, with consistent quality and at reasonable costs.


Jergens Solid Drive Spring Plungers offer a clear advantage over conventional spring plungers. Made of one integral piece of steel, Solid Drive Spring Plungers incorporate hex drive, plunger, and body, and are available in inch (2A-UNC) and metric (Class 6g) thread sizes. Through-hardened steel tips provide extra durability, and the close tolerance between tip and body provides better fit between parts for smooth motion and the precision and reliability required in workholding applications.


The Solid Drive design eliminates the need for a set screw. Torquing down a set screw creates a concentrated point force that can separate it from the plunger body. Solid Drive Spring Plungers also do away with lost springs and the need for “easy-out” tools. Additionally, with Jergens Solid Drive, the user can be sure the spring plunger is turning and not just the set screw.


Jergens Shortie Spring Plungers are made to the same quality standards as standard plungers, but are shorter in length. Because of their smaller size, Shortie plungers feature a screwdriver slot instead of a hex drive.


Jergens Spring Plungers are available in low carbon steel or stainless with Delrin, low carbon steel, or stainless tips and in a black oxide finish.
