STROCO manufactures nut plates that come in all shapes and sizes. If you do not see a part that meets the needs of your application, contact our engineers and they will work with you to develop a solution.

The nut plate was invented in 1960 by STROCO Manufacturing Inc. to facilitate a quick means for mounting electrical connectors and other components in confined areas of panels and bulkheads. Working in such tight areas led to dropped parts and long installation times. The STROCO nut plate eliminates loose nuts and washers thus saving installation time. With one screw started from the outside of the panel, the other three nuts in the plate automatically self align with the mounting holes. The nut plate mounts from the blind side of the panel, eliminating the need for wrenches or nut drivers, thereby allowing for closer positioning of the connectors in the design.

The self-locking nuts are pressed into the nut plate, eliminating the problem of dropping or losing hardware behind panels and cable harnesses during installation. When installed on a cable assembly, the STROCO nut plate becomes a captive part eliminating loose pieces, adding stability, and saving valuable time!
