SS304 DIN125/GB97 M22 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.

Our SS304 DIN125/GB97 M22 Flat Washers are ideal for industrial and mechanical applications. ​

This flat washer is manufactured in strict accordance with DIN125 and GB97 standards with precise dimensions. Its inner diameter is 22mm, and the tolerance is controlled within a very small range to ensure a tight fit with M22 bolts or nuts; the outer diameter is 39mm, which can effectively disperse pressure and avoid local stress concentration; the thickness is 3.3mm, which provides stable and reliable support while ensuring structural strength. ​

The material is made of high-quality 304 stainless steel with a density of 7.93g/cm³, a chromium content of over 18%, and a nickel content of over 8%. It is also known as 18/8 stainless steel in the industry. This gives it excellent comprehensive performance, can withstand high temperatures up to 800℃, and is suitable for a variety of high-temperature environments. At the same time, its excellent corrosion resistance makes it fearless of harsh conditions such as moisture, acid and alkali, greatly extending its service life. The good toughness of 304 stainless steel ensures that the washers are not easily deformed or damaged under complex working conditions.

In practical applications, it has a wide range of uses. Placed under the head of the bolt or nut, it can form a smooth support surface on the surface of the connected parts, evenly distribute the load, prevent the surface of the connecting parts from being damaged due to excessive local pressure, and enhance the stability of the connection. It is often used in construction, machinery manufacturing, automobile industry, shipbuilding and other industries to provide reliable guarantees for the fastening of various equipment and structures. Whether it is daily equipment maintenance or large-scale engineering construction, SS304 DIN125/GB97 M22 Flat Washers are your trustworthy and high-quality choice.
