High-Quality Tiny Screws Supplier | M0.3 to M2.0 Precision Micro Fasteners

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.

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.

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.

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.
