4 Key Advantages of Our High-Precision Tiny Screws Manufacturing

Ultra-Miniature Precision (M0.3 to M2.0)

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

Diverse Design Capabilities for Niche Needs

Offer over 80 head styles (flat, pan, hex, countersunk) with custom engravings and coatings (PTFE, DLC). Our engineering team converts sketches to production specs within 8 hours, enabling rapid prototyping for unique uses like watch mechanisms, micro-robotics, and miniature sensors.

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 (0.01-0.15N·m), preventing stripping in delicate assemblies for electronics or medical devices.

Scalable Solutions for All Order Sizes

No minimum order restrictions: supply 100-piece samples for R&D or 10 million+ pieces for OEMs. Direct raw material sourcing cuts costs by 20%, while modular tooling reduces setup times for urgent orders—delivering prototypes within 72 hours.

As a precision tiny screws maker, we specialize in components requiring sub-micron accuracy. Our Swiss-type lathes with digital collet chucks enable us to produce screws with thread pitches as fine as 0.2mm. Each screw is measured with optical comparators and coordinate measuring machines (CMM) to ensure dimensional consistency.
