Micro Screw Product Range: M0.6 to M6 Selection Overview

Micro Screw Product Range: M0.6 to M6 Selection Overview

Micro and precision small screws are the most basic yet critical fasteners in electronics, optics, medical and smart hardware. This range covers metric M0.6 to M6 in multiple head styles, drives and materials for everything from consumer electronics to precision instruments. This article reviews the range to help buyers and engineers locate specs quickly.

Coverage and Thread Range

The range focuses on metric threads: M0.6 and M0.8 for optics and tight spaces, M1.2 to M2.6 for TWS earbuds, smartwatches and small consumer electronics, M3 to M6 for boards, covers and structures. Imperial sizes such as #00-90, #0-80 and #2-56 are available on request. Thread forms include machine threads for metal tapped holes and self-tapping threads for plastic bosses.

Standard lengths range from 2mm to 20mm; special lengths can be custom-drawn. All sizes match corresponding bits and torque tools for automated assembly.

Head Styles and Drives

Pan heads offer large bearing surfaces and are most common; countersunk heads sit flush on covers; low-profile heads fit tight laptops and tablets; socket heads use internal hex or torx. Drives cover Phillips (PH), Torx and hex socket—Torx performs better against cam-out on auto lines.

Heads can be customized with flange faces, washer assemblies or security pins.

Materials and Finishes

Common materials include SUS304 stainless (rust-resistant, non/weak magnetic), SUS316 (high corrosion resistance), carbon steel (high strength, zinc-plated) and brass/nickel-plated copper (conductive, cosmetic). Finishes include natural, nickel, black zinc and black coating, matched to appearance, conductivity and corrosion needs. Clean packaging is available for medical and optics customers.

Applications and Customization

The range is widely used in consumer electronics, phone structures, cameras, medical devices, wearables and instruments. Beyond standards, we offer custom head forms, special pitches, pre-applied thread locker, screw-washer assemblies and tape packaging for drawings. Sampling and bulk orders both welcome.
