Brass Fasteners for Automotive Industry
Automotive applications demand fasteners that withstand heat, vibration, fuel exposure and electrical requirements simultaneously. Brass fasteners meet all these demands — corrosion-resistant to fuels and coolants, non-sparking for fuel system safety, and electrically conductive for sensor and grounding applications.
Why Brass for Automotive Industry?
Heat Resistance
Brass retains strength at temperatures up to 200°C — suitable for under-bonnet applications.
Fuel Compatibility
Excellent resistance to petrol, diesel, LPG and ethanol fuel blends.
Non-Sparking
Brass is non-sparking — essential safety requirement for fuel system components.
Vibration Resistance
Rolled threads in brass maintain clamp load under engine vibration.
Corrosion Resistance
Brass resists coolant, brake fluid and automotive chemical exposure.
Machinability
C360 brass enables high-volume precision machining of complex automotive parts.
Automotive Industry Applications
Fuel Systems
Fuel line fittings, carburettor jets, fuel injector components and LPG valve bodies.
Sensor Housings
Temperature sensor bodies, pressure sensor housings and transducer fittings.
Electrical Systems
Battery terminal bolts, grounding studs and connector fasteners.
Engine Components
Oil pressure fittings, coolant connections and drain plugs.
Brake Systems
Brake line fittings, caliper bolts and hydraulic system components.
Dashboard & Interior
Trim fasteners, instrument panel standoffs and interior assembly hardware.

Frequently Asked Questions
Are brass fasteners safe for fuel system applications?
Yes. Brass is the standard material for fuel system components due to its excellent resistance to petrol, diesel, LPG and ethanol, its non-sparking properties and good pressure resistance. C360 brass is widely used for carburettor jets, fuel fittings and LPG components.
Can brass fasteners withstand automotive operating temperatures?
Brass retains good mechanical properties up to approximately 200°C, making it suitable for most under-bonnet applications. For extreme temperature applications above 200°C (exhaust systems), stainless steel or high-temperature alloys are recommended.
What is the minimum order quantity for automotive brass fasteners?
For standard automotive brass fasteners, MOQ is 1,000 pieces. For custom CNC machined automotive parts, MOQ starts from 500 pieces. OEM supply programs with regular delivery schedules are available — contact our sales team.
