RS PRO Tırtıklı Vida, UNC 4-40, Vidalama Kapağı İle Kullanım

RS PRO Zinc-plated mild steel jack screws for use with screw down covers (covers not supplied).

These types of jack screws can be used to hold D-sub connectors together. When unscrewed, they allow the connector halves to be taken apart. These small jack screws have screw heads that enable the user's fingers to turn the jackscrew. The head can have an internal female thread, with the male externally threaded screw shaft extending from that.
