Mild Steel Washers are high-precision hardware components widely used in shafts, hinges, and mechanical assemblies. As flat washers, they are placed between moving parts to evenly distribute load, reduce friction and wear, and generate controlled torque during operation. This ensures smooth rotation, strong connections, and long service life.
Available in multiple surface treatments including environmental nickel, chemical nickel, black oxide, and zinc-nickel alloy, these washers offer excellent corrosion resistance and aesthetic appearance.
