SS304 DIN125/GB97 M12 Flat Washers

Made from 304 stainless steel, they exhibit exceptional corrosion and heat resistance, making them suitable for harsh environments. These washers feature a flat, disc-like shape and are designed to be placed between bolts and nuts.Their primary function is to distribute pressure evenly across the bolt head, protecting the connection surface from damage. Additionally, SS304 flat washers prevent bolts from loosening, ensuring a secure fit. Their precision thickness and smooth finish guarantee a reliable performance in applications requiring high precision and durability.

This SS304 DIN125/GB97 M12 Flat Washers is manufactured in strict accordance with the German industrial standard DIN125 and the Chinese national standard GB97. It is specially designed for M12 specification bolts, and the inner diameter is precisely matched to ensure stable installation. The product is made of high-quality 304 stainless steel, with an austenitic alloy formula containing 18% chromium and 8% nickel, which gives it excellent corrosion resistance and high temperature resistance. It can work stably in an environment of -196℃ to 800℃, and can easily cope with harsh working conditions such as humidity, acid, alkali and high temperature. ​

The washer is flat and disc-shaped, and the surface is precisely processed, smooth and flat, with a roughness as low as Ra≤1.6μm, and a thickness tolerance of ±0.05mm, ensuring that the pressure is evenly distributed on the bolt connection surface, effectively preventing indentation and deformation of the contact surface, while improving the anti-loosening ability of the bolt and reducing the risk of loosening caused by vibration. Whether it is machinery manufacturing, building steel structure, or high-precision fields such as aerospace, medical equipment, etc., it can provide reliable support.​

The product is widely used in chemical equipment pipelines, automobile engine parts, outdoor steel structures and other scenarios. With its durability and no rust or deformation, it provides long-term protection for various connection systems. Its international standard certification ensures that the material composition and mechanical properties meet the standards. It also supports customized coating treatments such as nickel plating and zinc plating to meet the special needs of different industries. It is an ideal choice for those who pursue quality and stability.
