Zinc-Plated Channel Nut

The channel nut is a fastener used in machine building, machine tool manufacturing and construction. Visually, it differs significantly from standard fasteners of this class.

Design features

The channel nut is not round or hexagonal like standard fasteners of this class, but rectangular. The threaded hole in the center remains an unchanged element of the design – such nuts are used during installation together with bolts, screws or studs.

The rectangular shape provides a more reliable connection: during installation the nut is secured over a larger area, which reduces the risk of the fastener stripping during operation.

The main feature of the design is the presence of a spring. This element absorbs external mechanical impact, dissipates external energy and prevents it from negatively affecting other elements of the structure. The same principle applies to channel nuts with a spring.

Channel nuts with a spring practically do not loosen during operation, unlike standard equivalents. This is especially important in the automotive industry, where structures are constantly subjected to mechanical impact and vibration during movement.

Materials and coating

Channel nuts with a spring are made from various materials: metal alloys, carbon steel or stainless steel.

Additionally, these fasteners are coated with zinc. This coating protects the metal from premature degradation and withstands aggressive environmental factors, such as precipitation and dirt. The service life of zinc-plated channel nuts with a spring is longer compared to fasteners without zinc plating.

Installation of channel nuts with a spring

Channel nuts with a spring are tightened using an automatic “gun” with a special attachment. The attachment must sit flush against the structure, without skewing – otherwise the reliability of the connection is reduced.
