Straight Tooth CNC Screws M4 Flat Head Quick Release Valve Screw For Automation Industry
Stainless steel straight tooth screws M4 flat-head quick-release screws, CNC screws
Precision Instruments / Optics / Automation Industry
Application Scenarios
Mainly used for core connections in high-precision equipment, including:
  • Fixing screws for optical lenses (camera lenses, microscope lenses)
  • Connecting parts for measuring instruments (profile projectors, coordinate measuring machines)
  • Fixing fasteners for robot joints and servo motors
  • Positioning screws for fixtures and jigs
Such fasteners require ultra-high precision and stability to prevent equipment measurement accuracy or operational stability from being affected by dimensional deviations.
Core Production Characteristics
Ultra-high Precision Control
Dimensional tolerance reaches ±0.003mm, with strict control over form and position tolerances including coaxiality, perpendicularity, and circular runout. Ultra-precision machining equipment (5-axis machining centers, ultra-precision grinders) combined with high-precision testing equipment ensures closed-loop precision control.
Low Stress & Stability Assurance
Low-stress machining processes reduce internal stress and prevent product deformation. Annealing, aging treatment, and optimized processing flows ensure mechanical properties and dimensional stability.
Customized Structural Design & Machining
Special structures including special shapes, multi-step profiles, double-end threads, limit shoulders, and special drive slots are customized according to specific equipment requirements. Customized machining molds and tools ensure perfect matching between products and equipment.
Improved Surface Quality & Wear Resistance
Surface finish reaches Ra ≤ 0.4μm, free of burrs and scratches. Surface strengthening processes (nitriding, hard chrome plating) enhance wear resistance and extend service life for long-term, high-frequency operation.
General Core Characteristics of CNC Machined Screws
  • Extremely High Precision: Standard tolerance ±0.01mm, precision version up to ±0.001mm
  • High Consistency: Program-controlled with high uniformity in batch dimensions
  • Flexible Customization: No mold opening required; fast switching for non-standard specifications
  • Wide Material Compatibility: Stainless steel, titanium alloy, aluminum alloy, copper alloy, high-temperature alloys
  • Flexible Efficiency & Batch Size: Suitable for small-batch prototyping and medium-batch customization
CNC vs. Traditional Screws Comparison
Comparison Items CNC Machined Screws Traditional Thread Rolling / Cold Heading Screws
Precision Extremely high (±0.001~±0.01mm) General (±0.05~±0.1mm)
Customization Very strong (non-standard / special-shaped / complex structures) Weak (mainly standard parts)
Batch Size Small batch / Medium batch / Single piece Mass production (starting from 10,000 pieces)
Materials Full compatibility (difficult-to-machine materials) Mainly low-carbon steel, aluminum alloy
Cost High unit cost Low mass production cost
Application High-end, precision, customized scenarios General standard parts, mass production
