Jack Screw Assembly Kits

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. As each D-Sub connector requires 2 screws, each Jack Screw Assembly Kit is individually packaged with 2 Screws, 4 Flat Washers, 2 Lock Washers and 2 Nuts. Other packaging options include the screw only or having each component packaged individually in Bulk.
