Kiran Industries are Copper Bolt Manufacturers in India with high-precision fasteners from premium-grade electrolytic copper using advanced machining technology. The company pays attention to correct threading, reduced sizes, and uniform finishes in its products. We rigorously examine all merchandise to meet industry standards, ensuring its reliable performance in electrical, marine, and engineering events. We also supply regular sizes and special sizes of copper bolts to meet the specifications of industrial and project work. Our fastening products have been associated with high quality, corrosion resistance, high electrical conductivity and great endurance.
We make copper bolts from high-purity copper material. The copper bolts do not rust when compared to the conventional steel fasteners and can work well in moist, coastal, and chemically exposed conditions. They also have a natural reddish metallic finish, which means that they can be used in exposed installations where looks and performance matter equally.
Copper is ductile and can be worked, and thus, installation is easier, and thread seizure is avoided. This feature enables tightening and loosening of the joint many times without causing any harm. Due to this, copper bolts are a reliable long-term fastening method, particularly in grounding and electrical connections.
Key Features and Benefits
Copper bolts are desirable when conductivity, safety, and environmental damage resistance are needed.
Main advantages:
- High corrosion resistance
- Very good electrical conductivity.
- Non-magnetic characteristics
- Anti-sparking properties
- Simple installation and uninstallation.
- Reliable long service life
These characteristics have made copper bolts very useful in electrical panels, substations, and earthing systems, where safety and conductivity are key considerations.
Types of Copper Bolts
Hex Head Copper Bolts
The most common type is tightened using a spanner or a wrench.
Applications:
- Electrical panels
- Earthing systems
- Mechanical assemblies
- Engineering installations
Square Head Copper Bolts
Ensure a sturdy grip while tightening and fitting the grounding connections.
Applications:
- Busbar joints
- Electrical equipment
- Structural mounting
Carriage Copper Bolts
Round head, square neck, so that it is not rotated when it is attached
Applications:
- Outdoor boards
- Wooden mounting plates
- Electrical structures
Countersunk Copper Bolts
The structure is designed to fit into the surface and provide a smooth finish.
Applications:
- Switchboards
- Electrical plates
- Ornamental electrical fittings
- Composition and Grades of Materials
- High-conductivity copper is used to produce copper bolts so that they are better in electrical conductivity and resistance to corrosion
Common grades:
- Electrolytic copper
- High-conductivity copper
- Copper, oxygen-free, special electrical
These grades will provide low electrical resistance and better operations in both grounding and bonding systems.

Surface Finish Options
Copper has an innate resistance to corrosion, though extra finishes can be used to enhance functionality and resistance.
- Natural copper finish
- Polished finish
- Tin-plated
- Nickel-plated
Tin plating is also effective in electrical installations since it does not oxidise and enhances conductivity stimulation in the long run.
Industrial Applications
Electrical Industry
Copper bolts are highly conductive and are widely used in switchgear panels, transformers, earthing systems and busbar connections.
Renewable Energy Systems
Copper bolts are used in the installation of solar power plants and wind energy systems as grounding/electrical bonding connections.
Marine Installations
Copper is an appropriate choice of material to be used in docks, ship fittings, and coastal equipment because it is resistant to corrosion in saltwater.
Lightning-Protection Systems
They are used in lightning arresters and grounding grids to ground electrical discharge safely in the ground.
According to the nature of the installation, there are chemical and outdoor installations.
These bolts are primarily used in outdoor electrical equipment and chemical plants, where corrosion resistance plays a crucial role.
Advantages Over Steel Bolts
Steel bolts have a greater mechanical strength, whereas copper bolts work in electrical and corrosive environments.
Compared to steel fasteners:
- Do not rust
- Better electrical conductivity
- Greater safety in grounding
- Easier maintenance
- Our copper bolts have a longer lifespan, even in wet conditions
