D-Sub Jackscrew Hardware — M3 Thread, Socket and Screw Set
It includes both the M3 socket and the M3 screw, so the set is complete in one order — no separate screw sourcing needed. The threaded portion below the head measures 0.315" (8.00 mm), which is the standard thread engagement length for securing a D-sub to a panel or mating connector half. Zinc plating provides corrosion resistance for indoor and light industrial environments.
Thread Size and Fit
The M3 socket and M3 screw thread size is the critical dimension for compatibility. This jackscrew mates with standard D-sub connectors that have M3 threaded inserts — the socket threads onto the mating screw, and the screw threads into the connector or panel. The 0.315" (8.00 mm) thread length is typical for standard-density D-sub shells; it provides enough engagement to pull the connector halves together without bottoming out.
Compatibility and Application
This jackscrew is for use with standard D-sub connectors. It serves as the jacking hardware that secures the mated pair and provides the mechanical advantage to overcome the insertion force of a multi-pin D-sub. In a typical assembly, the socket half is installed on the cable-mount connector, and the screw half on the panel-mount connector — or vice versa, depending on the application. The zinc plating handles the occasional moisture exposure of a control cabinet or test rack, though it is not rated for submersion.
