4 Core Advantages of Our High-Precision Micro Screws Manufacturing

Ultra-Micro Precision Engineering (M0.3-M2.5)

Specializing in screws as small as M0.3 with ±0.003mm tolerance, our Swiss-type CNC lathes craft intricate threads and heads for medical devices, electronics, and aerospace. Materials include 316L stainless steel, titanium Grade 5, and PEEK, ensuring biocompatibility, corrosion resistance, and heat stability.

Diverse Design Capabilities for Niche Needs

Offer over 100 head styles (flat, pan, hex, countersunk) with custom engravings and coatings (PTFE, DLC). Our 3D modeling team converts client sketches into production specs within 8 hours, enabling rapid prototyping for unique applications like watch mechanisms or micro-robotics.

Automated Quality Control for Mass Consistency

Fully automated optical sorting systems inspect each screw for thread pitch, head diameter, and surface finish, achieving 99.8% pass rates. In-line torque testing ensures optimal fastening force (0.01-0.2N·m), preventing stripping in delicate assemblies.

Scalable Solutions for All Order Sizes

No minimum order restrictions: supply 100-piece samples for R&D or 10M+ pieces for OEMs. Direct raw material sourcing (from Sumitomo Metal) cuts costs by 20%, while modular tooling reduces setup times for urgent orders (72-hour turnaround for prototypes).
