Brass Bolts are widely used fasteners designed for corrosion resistance, electrical conductivity, and long service life in industrial and engineering applications. We are one of the leading manufacturers and exporters of Brass Bolts from India. We have been supplying Brass Bolts to the world market for many decades. Our precision-engineered Brass bolts are manufactured using high-quality Brass alloys and advanced machining technology to ensure consistent thread accuracy, dimensional stability, and superior mechanical performance. Brass fasteners are widely preferred in marine environments, electrical installations, switchgear equipment, plumbing systems, and decorative hardware because of their non-corrosive and non-sparking properties. With more than three decades of global manufacturing experience, we produce Brass bolts conforming to international standards such as ASTM, BS, DIN, ISO, IS, and JIS. Our production facilities include CNC machining, forging, thread rolling, and quality inspection systems that ensure superior product quality. Standard production lead time is 4–6 weeks depending on size and order quantity.
Overview of Brass Bolts
Brass bolts are threaded fasteners manufactured from Copper-Zinc alloys that offer excellent corrosion resistance and aesthetic appeal. These bolts are commonly used with nuts to join mechanical components, structural assemblies, and equipment parts. Compared with ordinary Steel fasteners, Brass bolts resist rust and corrosion, making them suitable for outdoor and marine environments. They are also widely used in electrical equipment because Brass has excellent electrical conductivity and is non-magnetic. Brass bolts are available in several head types such as hex head, square head, flange head, and countersunk designs. Their smooth surface finish and attractive golden appearance make them ideal for decorative and architectural hardware as well.
Types of Brass Bolts
Brass bolts are manufactured in various configurations depending on application requirements.
| Type | Description |
|---|---|
| Hex Head Brass Bolts | Standard industrial fasteners |
| Square Head Brass Bolts | Used in traditional mechanical assemblies |
| Flange Brass Bolts | Integrated washer for load distribution |
| Machine Brass Bolts | Used in machinery and equipment |

Material Grades & International Standards
We manufacture Brass bolts using high-quality Brass alloys that comply with international specifications.
| Standard | Grade | Description |
|---|---|---|
| ASTM | C36000 | Free Cutting Brass |
| ASTM | C37700 | Forging Brass |
| BS | CZ121 | Free Machining Brass |
| DIN | CuZn39Pb3 | German Brass Alloy |
| EN | CW614N | European Brass |
| IS | IS 319 Grade I | Indian Brass |
| JIS | C3604 | Japanese Brass |
| GB (China) | HPb59-1 | Chinese Equivalent |
These material grades ensure excellent machinability, strength, and corrosion resistance.
Manufacturing Process of Brass Bolts
Brass bolts are manufactured through hot forging or precision machining processes. The process begins with cutting Brass rods or billets followed by hot forging to form the bolt head. After forging, CNC turning operations produce the shank and threaded section. Thread rolling or thread cutting machines generate accurate metric, UNC, UNF, or BSW threads. The bolts are then deburred, polished, and cleaned. Surface finishes such as natural Brass, Nickel plating, Chrome plating, or Tin coating are applied depending on application requirements. Each batch undergoes dimensional inspection, thread gauge testing, and mechanical property testing to ensure compliance with international standards.
Typical Size Chart for Brass Bolts
| Bolt Size | Thread Pitch | Length Range | Head Type |
|---|---|---|---|
| M4 | 0.7 mm | 10 – 40 mm | Hex |
| M6 | 1.0 mm | 12 – 80 mm | Hex / Flange |
| M8 | 1.25 mm | 20 – 120 mm | Hex |
| M10 | 1.5 mm | 25 – 150 mm | Hex |
| M12 | 1.75 mm | 30 – 200 mm | Hex |

Physical & Mechanical Properties of Brass Bolts
| Property | Typical Value |
|---|---|
| Density | 8.4 – 8.7 g/cm³ |
| Tensile Strength | 300 – 500 MPa |
| Yield Strength | 100 – 250 MPa |
| Hardness | 80 – 150 HB |
| Melting Range | 900 – 940°C |
These properties make Brass bolts durable, corrosion-resistant, and easy to machine.
Machinery Used in Production
Production of Brass bolts involves advanced manufacturing equipment such as hot forging presses, CNC turning centers, thread rolling machines, automatic screw machines, polishing machines, and quality inspection instruments such as thread gauges, micrometers, and coordinate measuring machines.
Industries Using Brass Bolts
Brass bolts are widely used in electrical switchgear manufacturing, marine equipment, plumbing systems, pump and valve assemblies, telecommunications equipment, automotive components, HVAC installations, and architectural hardware.
