Precision CNC Machined Bolt Fasteners - For Automotive, Construction & Industrial Machinery
Product Description
Our CNC machined bolt fasteners are engineered to deliver exceptional strength, dimensional accuracy, and reliability across critical industries. Manufactured with tight tolerances (±0.01mm) and premium materials, these bolts ensure secure, vibration-resistant connections in the most challenging environments.
Key Features & Benefits
✔ Premium Materials:
Stainless Steel (304/316) - Corrosion resistance
Alloy Steel (Grade 8.8/10.9/12.9) - High tensile strength
Titanium - Lightweight aerospace-grade
✔ Precision Manufacturing:
CNC Turning & Thread Rolling for perfect thread engagement
Heat Treatment (Quenching & Tempering) for enhanced durability
Surface Finishes: Zinc-plated, Hot-Dip Galvanized, Dacromet, or Black Oxide
✔ Wide Application Coverage:
Automotive: Engine blocks, chassis, transmission systems
Construction: Steel structures, bridges, heavy equipment
Industrial Machinery: Pumps, valves, conveyor systems, dies
✔ Custom Solutions Available:
Non-standard lengths/diameters
Special thread profiles (Metric, UNC, UNF, Whitworth)
Unique head designs (Flange, Countersunk, Shoulder)
