Product Description

Nuts are parts that tightly connect mechanical equipment. Through the inner thread, nuts and bolts of the same specifications can be connected together. For example, M4-P0.7 nuts can only be connected with M4-P0.7 series bolts (in nuts, M4 means that the inner diameter of the nut is about 4mm, and 0.7 means that the distance between two thread teeth is 0.7mm); the same is true for American products, for example, 1/4-20 nuts can only be matched with 1/4-20 screws (1/4 means that the inner diameter of the nut is about 0.25 inches, and 20 means that there are 20 teeth in every inch).

Gnee Rails specializes in the production of various national and export standard metric and American nuts.

Product Classification

Depending on the material and purpose, nuts are divided into several major types such as carbon steel, stainless steel, and non-ferrous metals (such as copper). As a railway equipment supplier with many years of experience, Gnee can produce the following nuts:

Stainless steel nuts

Stainless steel nuts are widely used in chemical, aviation, military equipment and other places requiring high safety, as well as large buildings and infrastructure such as railways, highways, power companies, bridges, etc.

stainless steel nuts

Stainless steel nut products:

Hexagonal nuts (GB6170/DIN934), thin nuts (GB6172/DIN439), heavy nuts (metric, American), nylon locking nuts (DIN985-DIN982 thick), all-metal locking nuts (DIN980M), cap nuts (DIN1587), flange nuts (GB6177/DIN6923), flange nut nylon locking nuts (DIN6926), four-corner welding nuts (DIN928), hexagonal welding nuts (DIN929), butterfly nuts (GB62, DIN315, American), K nuts, etc. Specifications: M1.6-M64.

Alloy steel nuts

Alloy steel is made by adding other metal elements to steel to improve its properties, such as increasing strength, hardness, corrosion resistance, etc. Nuts made of this material have higher strength and wear resistance.

alloy steel nuts

Alloy steel nut products:

Hexagonal nuts (GB6170/DIN934, GB6175), flange nuts (GB6177/DIN6923), round nuts (GB812), small round nuts (GB810), American square nuts, American hexagonal nuts (ANSI/ASME B18.2.2), heavy nuts (metric, American). Specifications: 5/16-4″.

DISC-LOCK anti-loosening nut

DISC-LOCK anti-loosening nut is composed of two parts, each part has a staggered cam. Because the internal wedge design slope angle is greater than the nut angle of the bolt, this combination is tightly bitten into a whole. When vibration occurs, the convex parts of the DISC-LOCK anti-loosening nut shift against each other, generating lifting tension, thereby achieving a perfect anti-loosening effect.

DISC-LOCK anti-loosening nut

Locking nut

Locking nut is also called root nut, anti-loosening nut, and nut. It is mainly used to lock the through-wire external joint or other pipe fittings. The self-locking reliability of the nut and bolt will be reduced under dynamic load, so some anti-loosening measures need to be taken to ensure the reliability of the nut locking. Its The locking nut is one of the anti-loosening measures, and there are different types.

lock nuts

Insert nut

Insert nut is made of copper nut made of various embossed wires (generally lead brass, such as H59, 3604, 3602), also known as copper nut, embedded nut, insert copper nut or plastic insert nut. According to different usage methods, it is divided into hot melt copper nut, hot pressed copper nut, insert copper nut and ultrasonic copper nut.

Insert Nuts
This product is widely used in mobile phone shell/notebook shell/injection molded parts/plastic parts embedded parts, used as an internal thread, generally embossed on the outer circle to prevent sliding.
