Types of Hex nuts
As a professional hex nuts manufacturer, Jinrui currently produces the following types of hex nuts (in addition, according to your usage, we can customize products, coatings, specifications, etc. that meet your needs):

Hex nuts
Hex nuts, screws, bolts, and screws are used in conjunction with each other to connect and fasten parts. Select the appropriate hex nut according to different usage scenarios.

Hex thin nut
Hex thin nut are used in conjunction with screws, bolts, and screws to connect and fasten parts. Select the appropriate hex nut according to different usage scenarios.

Hex nylon lock nut
The hex nylon lock nut is a kind of high anti-vibration and anti-loosening fastener. Because it has a nylon ring, it can provide strong friction when tightening, so the fastening ability is relatively improved. It is mainly used in conjunction with screws, bolts, and screws. Play the role of connecting fastening parts. Select the appropriate hex nut according to different usage scenarios.

Hex metal self-locking nut
The hexagonal metal self-locking nut is the same as the hex nylon lock nut, which enhances the fastening ability by increasing friction. The difference is that the nylon ring inside the metal self-locking nut is replaced by a metal ring. It is mainly used in conjunction with screws, bolts, and screws to connect and fasten parts. Select the appropriate hex nut according to different usage scenarios.

Features and Advantages of Hex Nuts
Metal hex nuts are the most versatile and one of the most common fasteners, complementing bolt fasteners. It is characterized by low cost and simple use. Some variants of hex nuts also have additional functions, such as hexagonal nylon lock nuts and hexagonal metal lock nuts. By inlaying nylon rubber rings or metal sheets in the hexagonal faces, Effectively prevent the threaded structure from loosening, so it is often used on powerful machinery.
There are many materials for hexagon nuts. At present, stainless steel hexagon nuts, carbon steel hexagon nuts, brass hexagon nuts, etc. are widely used. Jinrui can manufacture the above products. As a hex nut supplier, Jinrui can customize hexagon nuts of other specifications such as m6 hex nuts, m8 hex nuts, m10 hex nuts, etc., and can provide surface treatment processes such as galvanizing for hexagon nuts.
