CNC precision stainless steel machining parts external hexagonal nuts numerical control

Covers core components for consumer electronics and telecommunications equipment, including internal fixing screws for consumer electronics such as mobile phones, computers, and tablets (for motherboards, screens, and battery fixation), fixing screws for connectors and PCBs, as well as precision fasteners for telecommunications equipment such as base stations and servers.

Such fasteners must adapt to the trend of miniaturization and lightweighting of equipment, while meeting functional requirements including conductivity, insulation, and rust resistance.

• Mainly small-sized screws from M0.8 to M3, with some products only 2-5 mm in length
• Miniaturized machining solves difficulties such as positioning challenges and unstable machining accuracy for small-sized products
• Micro cold heading machines and precision CNC lathes with dedicated micro-cutting tools
• Optimized machining parameters ensure clear threads and accurate dimensions
• Strict control of verticality and coaxiality to maintain assembly accuracy of electronic devices

• Lightweight materials including aluminum alloy, copper alloy, and titanium alloy
• Material selection based on application requirements:
  • Copper alloy for PCB screws to improve conductivity
  • Aluminum alloy for heat dissipation component screws to enhance thermal conductivity
• Optimized machinability to prevent embrittlement and deformation
• Ensured product strength meets assembly requirements

• Structures include countersunk head, torx drive, cross recess, security drive, and ultra-thin head
• Countersunk and ultra-thin heads avoid protrusion and preserve appearance and hand feel
• Torx and security drives prevent disassembly by non-professionals and improve equipment safety
• Precisely machined slot dimensions for perfect screwdriver matching
• Optimized thread structures improve assembly efficiency and avoid thread slipping

• Different surface treatments applied according to functional requirements:
  • Anodizing: Improves wear resistance and appearance of aluminum alloy screws
  • Nickel plating: Enhances rust resistance and conductivity
  • Gold plating: Improves conductivity and corrosion resistance for high-frequency telecommunications equipment
• Controlled coating thickness and uniformity to prevent peeling and oxidation
• All surface treatments comply with environmental standards for electronic devices, such as RoHS

• Ultra-high precision: Normal tolerance ±0.01 mm, precision version up to ±0.001 mm, with precise, gap-free thread matching
• High consistency: Program-controlled, with high uniformity in dimensions, geometric form, and surface quality in mass production
• Flexible customization: No mold required, enabling fast switching for non-standard pitches, special heads, multi-step shafts, and special drive types
• Wide material compatibility: Capable of machining stainless steel, titanium alloy, aluminum alloy, copper alloy, high-temperature alloy, etc.
• Flexible efficiency & batch size: Suitable for small-batch prototyping and medium-batch customization, supporting single-piece and multi-variety fast switching
