Channel nut without spring

The channel nut is a special type of fastener. It differs from standard equivalents in appearance. There is no familiar round or hexagonal shape here. The channel nut is made in the form of a rectangle.

Design features

The rectangular shape is not chosen by chance. This design allows for a more reliable fastening of elements in various structures: the channel nut covers a larger area and does not rotate during use, a problem that standard fasteners often have. That is why channel nuts are frequently used in machine building for assembling automotive systems, especially those that are constantly subject to mechanical loads and vibration.

The only thing that channel nuts have in common with standard-shaped fasteners is the hole in the middle. It has a thread cut into it, which is used to connect with bolts, screws and other auxiliary fasteners.

Channel nuts are made in various sizes. The most common fasteners are those with a hole diameter from 6 to 12 millimeters. They are most often used in machine building and other industries.

Manufacturing of channel nuts

Like all fasteners, channel nuts are made on special machines using cold stamping. For this, metal blanks are taken, given the required shape, and then a hole of the required diameter is punched. The final step is thread cutting.

Various metal alloys are used as material for channel nuts. Their grade depends on the application of the fasteners. Carbon steel or stainless steel is most often used, as they are stronger and more durable.

To extend the service life of the fasteners, after stamping they are zinc-plated: a zinc-based solution is applied. As a result, the corrosion resistance of channel nuts is improved — they withstand aggressive environmental effects, do not rust, do not deteriorate, and provide reliable fastening for a long time.

Installation of channel nuts

An automatic “gun” is used to install rectangular nuts, which tightens them quickly. It is important to ensure that the fastener is pressed evenly against the surface, otherwise the grip will not be reliable enough.
