RS PRO Stainless Steel Plain Washer, 6.4mm ID, 12mm OD, 1.6mm Thickness, DIN 125A, 250 Pcs 527-404

The RS PRO 527-404 Stainless Steel Plain Washer is engineered to support a wide range of fastening applications, bringing both reliability and corrosion resistance to industrial, commercial, and construction projects. These washers are manufactured to the DIN 125A standard, ensuring precise tolerances and consistent quality for professional use.

Constructed from A2 grade stainless steel, these plain washers offer exceptional resistance to corrosion, making them ideal for use in challenging environments such as chemical processing, food handling, and exterior construction. The 6.4 mm inside diameter is perfectly matched for use with M6 fasteners, while the 12 mm outside diameter and 1.6 mm thickness provide optimal surface bearing area and spacing to help prevent distortion or wear of joining materials.

The plain washer format is a key component in any bolted joint, serving to distribute the load from the nut or screw head across a larger area. This minimizes the risk of deformation or damage to the part being fastened, especially when dealing with softer substrates or requiring repeated maintenance. The use of high-grade stainless steel further extends the working life of assemblies, even in moisture-prone or corrosive settings.

With each bag containing 250 washers, this product facilitates efficient inventory management for maintenance departments, assembly lines, or field crews handling large volumes of fastener installations. Their consistent dimensions and compliance with international standards ensure compatibility with a wide range of metric hardware, particularly in settings where reliability is critical.

Applications for these plain washers include electronics enclosures, control panels, frames, flanges, piping assemblies, machinery, architectural fittings, and general industrial equipment. The corrosion-resistant properties allow safe usage in environments subject to cleaning, moisture, or chemical exposure.

Choosing RS PRO's DIN 125A stainless steel washers guarantees a balance of performance, durability, and cost-effectiveness for routine fastener needs. Whether you are managing a facility, fabricating equipment, or conducting routine repairs, these washers are well-suited for the job, offering precise fit and enduring strength.
