6Ways to Fix a Nut

How to tighten a small nut has always been an enduring topic in mechanical design. Everyone knows it well that is Japan’s eccentric nut and China’s self-tightening nut. However, instead of talking about the stars of the fastener industry today, let’s talk about the most basic methods of fixing nuts at work. We will introduce 6ways to fix nuts now.

Add flat washers

Metal Washer refers to the part between the connection piece and the nut. It is generally a 平座金, which is used to protect the surface of the connected piece from being scratched by the nut and to disperse the pressure of the nut on the connected piece.

Spring Washers And Flat Washers

Spring washers are widely used in the load-bearing and non-load-bearing structures of general mechanical products. They are characterized by low cost and easy installation. They are suitable for parts with frequent assembly and disassembly. But the anti-loosening ability of the spring washer is very low

Self-locking nut

The general nut will loosen itself due to vibration and other reasons during use, such as vibration. In order to prevent this phenomenon, the 自動ロックナット was invented. The main functions of self-locking nuts are anti-loose and anti-vibration. For special occasions.

Its working principle is generally self-locking by friction. The types of self-locking nuts classified by function include those with nylon rings, those with neck closures, and those with metal anti-loosening devices. They are all effective torque-type locknuts.

Due to their nature, self-locking nuts are difficult to screw.

Liquid fixative for screws and nuts

Apply the nut anti-loosening liquid to the tightened part of the bolt, and then screw on the nut to achieve the effect of anti-loosening.

Double Nuts(right and left)

The double anti-loosening nuts is two nuts with the same rotation direction. After the two nuts are tightened, they are tightened left and right as shown in the picture, so that the top force is generated between the two nuts, so that the bottom nut and the gasket generate friction. It generates friction with the second nut, and the double friction achieves the effect of preloading. This is also a good method.

Drill a hole in the screw and nut and put a split pin

In machinery, pins are mainly used for assembly positioning, and can also be used as overload shear connections in connection and relaxation level safety devices. The types of pins are cylindrical pins, tapered pins, hole pins, cotter pins, and safety pins.
