smallscrew Ultra-fine Micro Fasteners, High-precision Tiny Screws for Electronic Equipment Fine Assembly With the thinning of electronic products and miniaturization of equipment components, traditional conventional screws can no longer adapt to the assembly requirements of ultra-narrow gaps, ultra-thin plates and micro cavities. Ultra-fine micro screws have become core supporting parts in the precision manufacturing industry. Specializing in the R&D and production of ultra-fine micro fasteners, smallscrew focuses on the processing of micro screws with ultra-fine specifications and ultra-precise tolerances, adapting to various high-end fine assembly scenarios with delicate thread shapes, accurate sizes and stable locking performance. 1. Ultra-fine Specification System for Micro Narrow Installation Space Smallscrew’s ultra-fine micro screw series covers a variety of rare and fine specifications in the industry, breaking the size limit of conventional small screws and focusing on micro and refined assembly scenarios. The product line includes ultra-fine self-tapping screws, ultra-thin head machine screws, mini precision locking screws and micro countersunk head fastening screws. With miniaturized design in diameter, thread pitch and head thickness, the screws can be easily installed in narrow internal spaces of electronic equipment, ultra-thin hardware plates and gaps of micro instrument components, solving common problems such as oversized screws, installation failure and shell dislocation in fine equipment assembly. 2. Delicate Precise Thread for Tight Engagement and Anti-slip Performance Ultra-fine micro screws with delicate threads are much harder to produce than ordinary fasteners, and are prone to incomplete thread shapes, rough threads and slipping. Adopting exclusive micro thread rolling technology, smallscrew finely polishes every thread with full, regular and uniform texture and accurate thread clearance. Even within a small force range, the screws can achieve tight engagement with smooth installation and stable locking. They are resistant to slipping and tooth collapse after repeated disassembly, perfectly adapting to the working conditions of frequent use and slight vibration of precision equipment. 3. Refined Surface Technology with Smooth Appearance and Excellent Texture To meet the high requirements of electronic, precision instrument and high-end hardware industries for accessory quality and appearance, all smallscrew ultra-fine micro screws adopt refined surface treatment technology. Stainless steel screws have smooth surfaces without burrs, scratches and rust spots; carbon steel screws undergo professional electroplating and passivation treatment with uniform and flat surfaces, featuring rust resistance, oxidation resistance and wear resistance. The smooth and rounded edges prevent scratching precision components and electronic parts, meeting the assembly and appearance standards of high-end fine equipment. 4. Accurate Working Condition Adaptation for High-end Refined Manufacturing Smallscrew ultra-fine micro fasteners are tailored for various high-end refined manufacturing industries. In the electronic field, they are suitable for the assembly of Bluetooth earphones, smart bracelets, micro cameras, precision circuit boards and small smart home accessories. In the instrument industry, they adapt to the component fixing of precision testing instruments, micro experimental equipment and portable meters. They are also widely used in micro hardware parts, precision toys, small medical accessories and communication equipment. Custom non-standard micro screws with special sizes, head types and strength grades are available to meet personalized refined fastening demands.
