D20420-12

The D20420-12 is a jackscrew designed for securing D-Sub, D-Shaped connectors. This jackscrew uses a hex key drive for easy installation and removal, and features a shallow thread depth to prevent overtightening.

Applications

Available in #4-40 UNC thread type, the D20420-12 is especially used in applications such as flat panel displays, such as medical monitors. With a 4.83mm (0.190”) hex keydriver, it offers a reliable and convenient way to secure connectors while also protecting the panel. With its low profile, the design offers a high-quality tight fit that conserves surface space.

Work Principle

The D20420-12 operates by using a thread type hex screw and a compatible hex wrench to secure the connector to the panel. During installation, the hex screw penetrates through the panel and the connector, and the hex wrench is used to adjust the tension accordingly. The screw’s durability ensures that it will not easily come loose during regular use.

The shallow thread depth of the screws prevents them from being over-tightened. This not only helps the connector be more secure, but also helps to prevent damage to the paneling which is critical when the device being connected is meant to be aesthetically pleasing.
