GB812 round nuts are a kind of round type nuts produced according to the Chinese national standard GB/T 812-1988. They are usually used in conjunction with bolts to secure or clamp mechanical parts. One of the main features of these nuts is that they have a rounded head and an internally threaded hole that can be matched to the bolt's external thread.
Stainless Steel (304/316): Offers superior corrosion resistance and is suitable for moist or corrosive environments. The 316 grade has additional molybdenum, providing even better corrosion resistance, especially in marine applications.
Carbon Steel: Provides good strength and is the most common material for bolts. It may require additional surface treatments like galvanizing for increased corrosion resistance.
Alloy Steel: Offers enhanced strength and durability. It is often used in high-stress applications where high tensile strength is required.
Advantage:
1. Universality: as a standardized part, GB812 round nuts are widely used around the world. 2. Strength: Usually made of high-strength steel, it can withstand large preload force. 3. Ease of Installation: Due to its round design, it can be easily installed and disassembled with a standard wrench or screwdriver. 4. Compatibility: able to work with a wide range of bolts and threaded holes.
Scope of
Application
1. Mechanical assembly: used for fixing components in mechanical equipment. 2. Building structures: used in the construction industry for fixing and fastening of structures. 3. Transportation: used in the assembly of cars, ships and airplanes. 4. electronic equipment: used in the fixing of housings or components of electronic equipment.
