Stainless steel precision machined parts, serrated adjusting screws, quick-release screws designed for high-end equipment, shipbuilding, and energy industries.
Covering core applications in industrial high-end equipment, shipbuilding, and energy equipment:
These fasteners must adapt to high loads and harsh working conditions (marine corrosion, high-altitude wind turbine environments), featuring high reliability and long service life.
Mainly large-size fasteners from M8 to M36; some wind power bolts can exceed M50, with tensile strength ≥ 1000 MPa to withstand heavy loads of high-end equipment and alternating loads of energy equipment.
Large-scale cold heading machines, forging presses, and optimized forging processes ensure uniform internal material structure. Heat treatment improves mechanical properties and avoids cracking or deformation in large-size products.
To solve corrosion in marine and chemical environments, corrosion-resistant materials such as duplex steel, Hastelloy, and titanium alloy are used to resist seawater, acid, and alkali media and extend service life.
Surface treatments (anti-corrosion coating, anodic protection) and thread anti-corrosion treatment further enhance corrosion resistance and prevent loosening caused by thread corrosion.
Anti-loosening and anti-falling structures (double nut locking, cotter pin fixing, thread sealant) ensure no loosening or disengagement under long-term high-frequency vibration and harsh environments.
Fatigue tests, corrosion tests, and structural optimization reduce stress concentration, improve fatigue resistance, and meet long-term stable operation requirements of high-end and energy equipment.
The industry requires both high-volume standard fasteners (ship deck bolts) and customized large-size / special-structure fasteners (wind turbine hub bolts).
Flexible production lines balance automated mass production for standard parts and precision machining for customized parts. A strict quality inspection system ensures compliance with industry standards for every batch.
Standard tolerance ±0.01 mm, precision version up to ±0.001 mm, with precise, clearance-free thread fitting.
Program-controlled, with high uniformity in dimensions, geometric form, and surface quality in mass production.
No mold required; quick switching for non-standard pitches, special heads, multi-step shafts, and special groove types.
Capable of machining stainless steel, titanium alloy, aluminum alloy, copper alloy, high-temperature alloy, etc.
Suitable for small-batch prototyping and medium-batch customization, with fast switching between single parts and multi-variety production.
| Comparison Item | CNC Machined Screws | Traditional Thread Rolling / Cold Heading Screws |
|---|---|---|
| Precision | Ultra-high (±0.001 ~ ±0.01 mm) | General (±0.05 ~ ±0.1 mm) |
| Customization | Very strong (non-standard / special / complex structures) | Weak (mainly standard parts) |
| Batch Size | Small / medium batch / single piece | Large batch (starting from 10,000 pieces) |
| Materials | Fully compatible (including difficult-to-machine materials) | Mainly low-carbon steel, aluminum alloy |
| Cost | High unit cost | Low cost in large quantities |
| Application | High-end, precision, customized scenarios | General standard parts, large-scale production |
