Product Description

Product Description

    Hexagon lock nuts have a hexagonal appearance which is convenient for wrench operation. Their unique locking designs, such as nylon inserts, metal deformation, etc., can effectively prevent loosening and remain fastened in vibrating or dynamic load environments. They are widely used in machinery, automotive, aerospace and other fields to ensure the reliability of connections and play a crucial role in guaranteeing the normal operation and structural safety of equipment.

 

Materials of Hex Lock Nut

 

Carbon steel: Such as Q235, 45 steel, 40Cr, etc. They have good strength and toughness, and are low in price. However, they are prone to rust and are commonly used for connecting general mechanical parts.

Stainless steel: Such as 304, 316, etc. They have strong corrosion resistance and wear resistance, and are suitable for occasions with high material requirements. 316 is more resistant to chloride ion-containing environments such as the marine environment.

Copper alloy: Such as brass, which has good electrical conductivity and thermal conductivity, and is often used for connecting electrical equipment.

Aluminum alloy: Light in weight and relatively low in strength, it is suitable for aerospace, automotive lightweight and other fields with strict requirements on weight.
Non-metallic materials: Such as nylon, which has the characteristics of anti-loosening, corrosion resistance, and insulation. It is suitable for electronic equipment and instruments with high anti-loosening requirements and small loads, but its strength and high-temperature resistance are poor.

Product Parameters

 

Thread Specifications	Coarse Threads: Commonly seen are M3, M4, M5, M6, M8, M10, M12, M16, M20, etc. Hexagonal lock nuts with coarse threads are widely used in general mechanical connection and fastening scenarios.   Fine Threads: Include M8×1, M10×1.25, M12×1.5, etc.
Width Across Flats Specifications	The width across flats is an important dimension of the hexagonal lock nut.
Height (Thickness) Specifications	The height of the hexagonal lock nut varies with different specifications. Generally speaking, the height of hexagonal lock nuts ranging from M3 to M6 is between 5 - 10mm, and that of nuts ranging from M8 to M12 is between 8 - 15mm.
Locking Torque Specifications	Hexagonal lock nuts of different specifications have corresponding recommended locking torque ranges. This is to ensure that the nut can be effectively locked to prevent loosening and will not be damaged due to over-tightening.
