Jack Screws

The standard 3/16” hex jack screw is often used to fasten cable connectors in electronic equipment. Jack screws can also be used to connect two connector halves. A jack screw set generally includes two flat washers, a lock washer, and a nut. Hex jack screws can be manufactured to meet specific industry standards and can be customized for particular end-uses.

Jack screw styles available in our online store include knurled and plain.
