Knurled cylindrical nuts are a type of nut that has a knurled texture on its outer surface, a design that provides better grip and easy manual rotation. Knurled nuts are typically used in applications that require frequent manual installation and removal.

Knurling Types: 1. Straight Knurling: Creates a straight line and groove pattern on the surface of the workpiece for applications requiring good alignment and positioning.  2. diamond knurling: creates diamond-like bumps on the surface of the workpiece, providing additional durability and decoration. 3. spiral knurling: creates a spiral texture on the surface of the workpiece for applications that require decoration or enhanced functionality.

Material: including carbon steel, alloy steel, stainless steel (such as 304, 316, 316L, etc.) and other materials, the specific selection depends on the working environment and application requirements.

Grade: The product grade is different mechanical properties grade (such as 4.8 grade, 8.8 grade, 10.9 grade,A2-70, etc.), these grades reflect the tensile strength, yield strength and other mechanical properties of the bolt. Different grades are suitable for different load bearing requirements and working environments.

Advantage:

1. Enhanced Friction: Knurled surface increases the friction between the nut and the hand, making manual installation and removal easier. 2. Improved Appearance: Knurling provides a unique visual effect and can be used as a decorative element to increase the aesthetics of a product. 3. Quick assembly: Knurled nuts can often be fastened manually, saving time with tools. 4. Anti-loosening: Some knurled nuts have a locking feature that prevents loosening due to vibration or other external forces.

Scope of 

Application

1. Machinery and equipment: In machinery and equipment, knurled nuts are commonly used to fix parts, such as machine tools, engines, etc. 2. Automotive industry: In the automotive field, knurled nuts are used to fix doors, bonnets, boot lids and so on. 3. Furniture: In furniture manufacturing, knurled nuts can be used to connect furniture parts, such as chairs, tables with folding parts. 4. electronic equipment: in electronic equipment, knurled nuts are used to fix control panels, housings, etc.
