Precision CNC Machined Brake System Fasteners with High Corrosion Resistance and

Automotive brake system nuts and bolts are high-strength precision fasteners dedicated to vehicle braking assemblies, widely used for brake assembly of passenger cars, commercial vehicles and new energy vehicles. Manufactured from dedicated high-tensile carbon steel, stainless steel and other raw materials, the products are formed by a combination of cold forging and CNC precision turning & milling.

Strict control is implemented over thread precision, head dimension, surface finish and fitting tolerance. Featuring high tensile strength and smooth thread engagement, our product portfolio covers brake caliper bolts, brake bracket nuts, brake pad fixing bolts, brake pipeline locking nuts and other specifications.

These fasteners deliver excellent vibration resistance, high and low temperature resistance, anti-rust and anti-loosening performance, capable of enduring alternating loads generated by continuous road vibration and frequent braking. Standard sizes are available for mass production, and non-standard structural customization based on drawings and samples is supported.

Priority forming is realized via cold forging, followed by integrated multi-axis CNC precision machining to accurately fabricate external threads, internal threads, mounting surfaces and positioning shoulders. Uniform and burr-free thread profiles effectively prevent thread slipping and incomplete locking during assembly.

Products feature high dimensional consistency and controllable tolerances within batches for smooth disassembly and assembly, meeting standardized assembly requirements for brake components and greatly improving production line efficiency.

Adopting special raw materials for automotive fasteners with quenching and tempering reinforcement treatment to meet tensile strength and yield strength standards. The fasteners withstand long-term impact loads and continuous vibration generated during braking and resist tensile deformation and fracture.

Suitable for critical load-bearing positions such as brake calipers, brake rotors and brake pipelines to maintain long-term stability of brake assemblies and reduce potential driving safety hazards.

Optimized for automotive under-chassis working conditions, the fasteners withstand alternating high and low temperatures, rain, sediment, salt spray and brake dust erosion. Optional surface treatments including black oxide, zinc plating and nickel plating provide effective rust and corrosion protection, mitigating seizure caused by long-distance outdoor driving, facilitating maintenance disassembly and extending fastener service life.

Precision thread matching combined with flat fitting bearing surfaces increases contact friction and minimizes spontaneous loosening triggered by continuous vehicle vibration. Suitable for scenarios with frequent braking on urban roads, bumpy pavements and heavy-load conditions, maintaining stable pre-tightening force of brake components.

Common standard specifications of brake system fasteners are in stock for short lead-time delivery. Custom services are available for special stepped screws, special locking nuts, unique thread pitches and non-standard lengths. The products fit R&D of new braking systems, component replacement and modification supporting demands of traditional fuel vehicles, new energy vehicles and engineering vehicles.
