Product Description

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
