Jack Screws
A Jack Screw is simply a 3/16” Hex, 4-40 Male-Female Standoff, that is 3/16” in length. What separates these is that you can choose the male-thread length that will best fit your application. These are also called Female Screw-Locks and are most commonly used in mounting D-Sub Connectors. Each Jack Screw is available as a stand-alone screw, but visit the Jackscrew Assembly and Jack Screw Bulk Kit Sections to purchase the complete set of mounting hardware.
