GB6175 is a Chinese national standard that defines the specifications and requirements for ISO8674 Type 2 hexagon nuts. These nuts are thicker than Type 1 Hexagon Nuts (GB6170) and are often used in applications where higher nut strength is required.GB6175 Hexagon Nuts are suitable for high strength bolted joints, such as steel structures, bridges and towers.

Carbon Steel: Typically used for general applications.

Stainless Steel: For environments where corrosion resistance is required.

Alloy Steels: Used in applications requiring high strength or high temperature resistance.

Advantage:

INCREASED THICKNESS: Thicker than standard hexagon nuts to provide higher preload and tightening strength.

HIGH STRENGTH: Typically made of high strength materials for high load applications.

COMPATIBILITY: Can be used with GB/T 1228 standard large hex head bolts.

Scope of Application

STEEL STRUCTURES: In the connection of steel structures, Type 2 Hexagonal Nuts provide extra strength and support. Heavy Machinery: In heavy machinery, these nuts can withstand high loads and pressures. Chemical industry: For equipment and piping connections in the chemical industry, especially when handling corrosive substances.

Main Features: Easy to install, integrity, no gasket, easy to remove, reusable, medium carbon steel can be made with 8.8, Class 10.9 and other high strength bolts are used in connection with the United States military - MIL-STD 1312 Vibration Test.

 Applications: Automotive industry -- cars, trucks, buses, compressors, construction machinery, wind power equipment, fasteners, agricultural machinery, casting industry, drilling equipment, shipbuilding industry, military, mining equipment, oil drilling RIGS (onshore or offshore), public rail transit, transmission systems, metallurgical equipment.
