Nut - Overview

A nut is a type of fastener with a threaded hole. Nuts are almost always used in conjunction with a mating bolt to fasten multiple parts together. The two partners are kept together by a combination of their threads' friction with slight elastic deformation, a slight stretching of the bolt, and compression of the parts to be held together.

Materials of Nut

☆Nuts are commonly made of metal, but other options are available.

☆Aluminum nuts are light, resistant to oxidation, thermal and electrical conducive, and easy to manufacture.

☆Brass nuts are strong, conductive, corrosion resistant, with low magnetic permeability.

☆Copper alloy nuts have good load capacity, wear resistance, and are suitable for dynamic loads.

☆Fiber-reinforced plastic nuts use industrial fabric reinforced urethanes. They are wear resistant.

☆Nylon nuts are made of a tough and resistant material. It has good pressure ratings.

☆Plastic nuts are inexpensive and corrosion resistant for light loads.

Use of Nut

Alternative Solutions

Common reasons for using loose nuts and bolts include the low cost per piece and easy assembly/disassembly. Many applications require only ‘finger-tight’ fastening, meaning no additional tools are required. If minimizing part count is beneficial to the application, the nut can be eliminated by tapping threads directly into the steel post or sewer pipe. However, this results in two disadvantages. Tapping the thin metal of an aluminum post creates softer and fewer threads, increasing the risk of failure.

Common Attachment Technologies

General threaded nuts are loose parts that mate with a male thread. But a wide range of specific applications see nearly every kind of attachment technology used to put threads on a metal panel or PCB. Self-clinching nuts are common enough to simply be called clinch nuts.

Precautions

When using Steel hex weld nuts, the following need to be noted:
☆Before use, it is necessary to confirm whether the welding position and welding quality are good.

☆Pay attention to adjusting the fastening force of steel hex weld nut when using to ensure the stability of fixing.

☆According to different operating environment of equipment, choose different materials and specifications of the nuts.
