Product Features 
-Full coverage of small to medium specifications, suitable for fine/conventional fastening: covering the core specifications of M2-M8 series, accurately matching the fastening needs of different thicknesses, load-bearing capacities, and fineness: M2/M3 are precision models, suitable for fine fastening of ultra-thin leather, electronic accessories, and precision hardware pieces; M4/M5 are universal models that are suitable for regular fixation of leather goods, furniture panels, and decorative pendants; M6/M8 is a reinforced version that is suitable for high torque fastening of thick metal plates, solid wood panels, and small equipment. It features a single set of male and female nails that precisely bite without additional nuts, making it suitable for various through-hole fastening scenarios.
-304 stainless steel is made of one material, which is rust proof and corrosion resistant in the whole scene: it is made of 304 food grade stainless steel by cold heading, without base material splicing and coating. It is rust proof, corrosion resistant and aging resistant from the nail head to the thread, and can withstand outdoor humidity, bathroom water vapor, industrial slight acid and alkali, sea water fog and other rust prone environments. It can also directly contact food/medical peripheral equipment to solve the pain points of nickel plated products that are prone to rust and coating fall off. The indoor and outdoor scenes are common, and the service life is much longer than that of ordinary metal products.
-Hexagonal drive design, high torque without slipping, more secure fastening: Different from conventional hand twisted Chicago screws, the nail head adopts a standard hexagonal groove design, which needs to be matched with an hexagonal wrench to drive tightening/disassembly, and can apply greater tightening torque. After tightening, the thread bite is tighter, and the anti vibration and anti loosening effects are excellent. It is suitable for vibration and easy displacement scenarios, completely solving the problem of slipping and weak fastening of small-sized hand twisted screws. The hidden design of the hexagonal groove makes the nail head flat and beautiful, without protruding burrs.

Wide Range of Applications 
-Precision handmade DIY and high-end leather goods production: Suitable for fine fastening of high-end leather, microfiber, canvas and other materials, such as handmade wallets, notebooks, leather carvings, briefcases, belts, guitar straps, etc. The M2/M3 is suitable for fine point fastening of ultra-thin leather, while the M4/M5 is a universal leather goods model. The hexagonal design can accurately control the fastening force to avoid excessive twisting force crushing the leather, and the detachable feature is convenient for replacing inner pages and adjusting accessories. The 304 stainless steel material does not rust and will not contaminate the leather.
-Precision hardware accessories and electronic equipment assembly: used for fixing ultra-thin metal sheets, precision hardware pendants, and electronic equipment casings/accessories, such as metal tags, instrument panels, small electronic components, and detachable fasteners for drone accessories. M2/M3/M4 small specifications are compatible with precision through holes, and the internal hexagonal high torque design prevents accessory vibration and loosening during equipment operation. 304 stainless steel is rust resistant and corrosion-resistant, suitable for dry/slightly humid working environments of electronic equipment, and there is no risk of metal coating peeling off and contaminating circuit boards.
-Furniture production and decoration: Suitable for fastening solid wood panels, wrought iron accessories, and outdoor furniture, such as customized wardrobe shelves, decorative picture frames, outdoor metal flower racks, balcony shelves, and anti-corrosion wood furniture splicing and fixing. M5/M6/M8 are universal reinforced versions, made of 304 stainless steel material that is not afraid of outdoor rainwater and moisture. The hexagonal fastening ensures that the furniture will not loosen during long-term use, and the countersunk version can also achieve invisible fastening, balancing practicality and aesthetics.
