Hexagon nut is one of the most common fasteners we see.Hexagon nuts look common, but a wide variety of classification, it is divided into 1 type, 2 type, thin, positive and negative teeth and other standards.There are also grades 4, 8, 10 and 12. It is also classified as type A, type B and type C nuts according to the precision of manufacture.Generally speaking, type A nuts and type B nuts are used in demanding environments, while type C nuts belong to A rough industry, generally grade 4 nuts, no heat treatment, the surface is natural.

Hexagon nut washer face type introduction

1. The inner/outer tooth lock washer and the inner/outer serrated lock washer mainly prevent the connecting part from loosening through the meshing force between the tooth tip and the plane of the connecting part and the small elasticity.

2. The spring washer relies on the friction between the elastic opening and the inclined opening and the plane to prevent the fastener from loosening;Saddle and wavy elastic washers rely solely on their elasticity to prevent loosening of the connection.The gaskets are widely used for joints that are often removed.

3. The function of the outer tongue retaining gasket is similar to that of the single lug securing gasket in that the outer tongue retaining gasket is inserted through its outer tongue into the inner hole of the connected member to limit the rotation of the nut or bolt.

4. Single/double lug stop washers use curved lug structure to fix the edges and nuts of the connected parts respectively, so that they can not rotate freely and play a loose role.

5. Pre-tightening gaskets, also known as pre-tightening indicator gaskets, can be used to control the tightening of bolts.The gasket consists of four parts: two flat gaskets, an inner ring with lower yield strength and thicker thickness, and an outer ring with higher yield strength and thinner thickness.

6. Square inclined washer, mainly used for pad in channel steel or I-steel inclined plane, so that the nut supporting surface and screw vertical, so as not to produce bending stress when the nut under stress.

A brief introduction to the advantages of hexagonal locking nut washer

1. Ensure that the clamping force of the connector is maintained under strong vibration, which is better than fasteners that rely on the friction of the lock.

2. Prevent loosening of bolts caused by vibration, and avoid related problems caused by loosening of fasteners;

3. Constant temperature, loose connection;

4. No special installation work, easy to install and disassemble;

5. Reusable and durable.
