Precision Turned Fasteners

Contact Tuoyuan Metal immediately to obtain a customized solution for Precision Turned Fasteners! As a professional manufacturer, in addition to supplying standard models from stock, we specialize in non-standard customization and provide comprehensive, one-stop OEM solutions.

Product Advantages

Unmatched Precision & Consistency: Adopting advanced CNC turning and Swiss-type turning technology, our precision turned fasteners achieve tight tolerances of ±0.005mm to ±0.01mm, with surface roughness controlled at Ra 0.2-0.8μm. Every unit undergoes rigorous testing from raw material incoming to finished product delivery, ensuring consistent dimensional accuracy and perfect interchangeability for seamless assembly.

Cost-Effective Production Solution: Compared with grinding or cold heading processes, our CNC turning technology offers 40-60% faster cycle times for small diameters, lower capital investment (only 1/3-1/10 of grinders), and avoids high mold costs of cold heading. The high degree of automation reduces manual intervention, improving production efficiency while controlling costs, suitable for both small-batch flexible production and large-volume mass production.

Strong Material Versatility: We process a wide range of materials to meet diverse industry needs, including stainless steel (AISI 304, 316L), carbon steel, brass (CW617N, C36000), aluminum, titanium alloys, and other specialty alloys. Each material is carefully selected for its strength, corrosion resistance, and machinability, ensuring the fasteners adapt to various harsh working environments.

Customization Capability: We support full customization based on your drawings and specifications, including thread types (M2-M12, UNF/UNC), head shapes (knurled, slotted, hex), dimensions, and surface treatments. Modular tooling systems enable product switching within 15 minutes, ensuring rapid response to your custom needs.

Superior Durability & Reliability: Through special surface treatments (zinc plating, nickel plating, chrome plating, heat treatment) and precision machining, our fasteners exhibit excellent corrosion resistance, wear resistance, and fatigue resistance. They can maintain structural integrity even in high-vibration, high-temperature, or humid environments, extending the service life of your end products.

Product Features

Precision Machining Craftsmanship: Utilizing high-precision CNC turning centers and multi-axis synchronization technology, we can process complex geometries such as micro-threading (M1 and smaller), contoured profiles, and undercut features in a single clamping, ensuring positional accuracy and reducing non-cutting time.

Optimized Thread Design: The threads are precision-machined with J-form threads or special-shaped threads to enhance fatigue resistance, increase friction between mating components, and improve locking effectiveness, preventing loosening under vibration and stress.

Excellent Surface Finish: The fasteners feature a smooth, mirror-like surface finish (Ra < 0.2μm optional) without secondary polishing, reducing friction in moving parts and enhancing both corrosion resistance and aesthetic quality.

Strict Quality Control: Equipped with advanced measuring and testing equipment, we implement full-process quality monitoring, including dimensional inspection, surface roughness testing, and material composition analysis, ensuring 100% qualified products are delivered to customers.

Eco-Friendly Manufacturing: Our production processes comply with environmental criteria and eco-sustainability requirements, using lead-free materials and environmentally friendly surface treatments to protect the environment and employee wellbeing.
