Stainless Bolts Industries, a leading manufacturer and supplier in India offer premium stainless steel fasteners, provides an exclusive variety of SS 304 Plain Washer designed for outstanding performance and durability. These plain washers, which are made from 304-grade stainless steel, are perfect for use in a variety of industries, including construction, marine, automotive, chemical processing, and food manufacturing, because of their exceptional resistance to rust, corrosion, and harsh weather conditions. The purpose of our SS 304 Plain Washers is to preserve the integrity of fastening assemblies, minimize surface wear, and distribute load uniformly. These washers, which are recognized for their toughness and reliability, are crucial parts of applications that call for strong and long-lasting fastening solutions.
A flat, circular metal part with a center hole, the SS 304 simple washer is often found in structural and mechanical components. Constructed from grade 304 stainless steel, it provides high strength, durability, and resistance to corrosion, making it appropriate for a variety of settings, including industrial, outdoor, and marine ones. In order to reduce damage to the surface being secured and lower the possibility of loosening due to vibration, a simple washer's main purpose is to distribute the load of a fastener, such as a bolt or nut, evenly. With 18% chromium and 8% nickel, SS 304 is a solid stainless steel alloy that is highly resistant to oxidation and wear while yet having acceptable formability and welding.

SS 304 Plain Washer are known for their outstanding ability to resist corrosion, high strength, and long-lasting performance, making them fit for a wide range of demanding applications across numerous industries:
Because SS 304 plain washers are made of premium stainless steel, they have a number of benefits. They are perfect for use in tough settings, such as the chemical and marine industries, because of their exceptional corrosion resistance. Their appropriateness for sensitive applications like as electronics and instrumentation is guaranteed by their non-magnetic nature when annealed. By supporting in the even distribution of load, these washers prolong the life of attached joints and lower the possibility of surface damage. Further, SS 304 washers have excellent yield and tensile strengths, ensuring dependable operation even under mechanical stress. They are also appropriate for high-heat situations because to their tolerance to high temperatures (up to 870°C). They are an affordable and long-lasting solution for both commercial and industrial applications, and they are simple to clean and maintain.
