D-Sub, D-Shaped Connectors - Accessories - Jackscrews

Jackscrews have been around since the mid-20th century. Developed in the 1950s, jackscrews are used to provide secure mounting between separate subcomponents or larger pieces of equipment. In the case of D-shaped connectors and accessories, jackscrews are typically used to attach a connector shell to the printed circuit board.

These types of screws typically function by either utilizing a hexagonal head or an internal hexagonal drive. Hexagonal-headed screws require a hexagonal-shaped driver for installation, whilst internal hexagonal drives are screwed in using a flathead driver with a hexagonal cross section.

Jackscrews are particularly useful for D-shaped connectors as their unique shape is laboring to form a consistant connection with other components. This makes them perfect for applications in which high levels of vibration or shock are expected, as jackscrews provide a firm attachment with no weak spots. Additionally, many jackscrew designs incorporate anti-loosening features, such as a nylon patch in the threads to create resistance and prevent the screw from loosening due to vibration.

The use of jackscrews for securing D-shaped connectors and other applications is essential to ensure a secure and consistent connection. Furthermore, due to their unique shape and designed anti-loosening features, they are the ideal choice for complex and demanding applications.

Jackscrews are available in a range of sizes and materials to suit a variety of different requirements and conditions. The range of sizes is particularly important, as using the correct screw size is essential to prevent over- or under-tensioning the connection. Over-tensioning can strip threads, whilst under-tensioning can lead to an unstable, insecure connection.

Jackscrews are essential components for any secure D-shaped connector or accessory installation. For the best results, careful consideration should be given to the size and materials of the screw, and the appropriate torque should be applied using a suitable torque driver during installation in order to create a reliable, secure connection.
