GB923 copper cap nuts, also known as cap nuts, are a common type of fastener. Designed with a round copper cap on top, this nut is typically used to protect threads and provide a good seal. Copper cap nuts can be used in a variety of applications including pipe connections, mechanical equipment and general engineering.

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:

GOOD SEALING: Copper caps can provide good sealing performance to prevent liquid or gas leakage. CORROSION RESISTANCE: Copper material has good corrosion resistance and is suitable for various environmental conditions. Protection of threads: the copper cap can protect the internal threads from damage and prolong the service life. EASY INSTALLATION: Works with standard bolts for easy installation.

Scope of Application

Pipeline connection: In pipeline system, it is used to fix and seal pipeline joints. Mechanical equipment: In various mechanical equipment, it is used to fix the parts to prevent loosening due to vibration. General Engineering: In general construction projects, used to fix structural components.
