Our stainless steel machine screws are made from 304 and 316 stainless steel, featuring outstanding corrosion resistance, oxidation resistance, and high-temperature resistance. They can work stably for long periods in humid, acidic, and alkaline environments.
As standard machine screw bolts, the products strictly follow international common size standards and also support a full range of non-standard customization. The head structure, thread specifications, and length tolerance can all be precisely developed and produced according to individual needs, meeting the exclusive fastening requirements of different equipment.
Each machine bolt undergoes multiple precise processes: from raw material cold forging, thread rolling, to surface passivation treatment and full inspection for shipment, the entire process follows ISO9001 quality management system and IATF16949 automotive industry quality system standards, ensuring that the mechanical properties, dimensional accuracy, and surface quality reach international first-class levels.
YH FASTENER's stainless steel machine screws deeply integrate into the global high-end manufacturing industry chain: In 5G communication base stations, they serve as the core machine screw bolts to ensure the stability of the signal transmission structure; in automotive electronic systems, stainless steel machine screws meet the strict safety standards of the automotive industry with excellent vibration resistance; in the consumer electronics sector, micro machine screws achieve precise micro-fastening of components, helping with lightweight design of products; in the aerospace sector, customized machine bolts support extreme environment operation requirements with ultra-high precision.
Relying on two modern production bases in Dongguan and Lechang (with a total production area of over 20,000 square meters) and the service layout in Wuhan, we can achieve large-scale production and rapid delivery of machine screw series products, providing stable supply guarantees for global customers.
