What is an M18 Brass Plain Washer?

An M18 Brass Plain Washer is a flat, circular disc with a central hole designed to fit perfectly around M18-sized bolts or screws. The purpose of an M18 Brass Plain Washer is to evenly distribute the force exerted by the fastener, protecting the surface material from damage and enhancing the clamping effect.

Made from high-quality brass, the M18 Brass Plain Washer is corrosion-resistant, electrically conductive, and dimensionally stable. These washers are widely used in plumbing fixtures, electrical enclosures, and general hardware assemblies. Due to their excellent resistance to rust and moisture, M18 Brass Plain Washer units are ideal for indoor and semi-exposed environments.

At Nafees Metal Industries, we ensure each M18 Brass Plain Washer conforms to international specifications for inner and outer diameter, thickness, and surface finish. Customers prefer the M18 Brass Plain Washer not only for its durability but also for its reliable performance across a wide variety of fastening requirements.

Whether you’re sourcing Brass Flat Washers for an industrial project or a contractor looking for consistent washer performance, the M18 Brass Plain Washer is a go-to solution trusted by industry professionals.

Why Choose Brass for M18 Washers?

The M18 Brass Plain Washer is crafted using high-grade brass, a material known for its excellent corrosion resistance, electrical conductivity, and aesthetic appeal. Brass is a preferred choice in environments where strength and moisture resistance are crucial, making the M18 Brass Plain Washer a reliable component for both indoor and moderately exposed applications.

Brass offers the additional advantage of being non-magnetic, which means the M18 Brass Plain Washer can be safely used in electronic assemblies without interfering with magnetic fields or signals. Furthermore, the M18 Brass Plain Washer retains its integrity under pressure, reducing the risk of deformation over time.

Unlike steel, brass resists oxidation naturally. This ensures that the M18 Brass Plain Washer maintains its performance and appearance even in corrosive environments. Its shiny gold-like finish also makes the M18 Brass Plain Washer suitable for visible or decorative applications where aesthetics matter.

Thanks to its durability and non-reactive properties, the M18 Brass Plain Washer is ideal for plumbing, marine, electrical, and automotive industries. When long-term performance is required, choosing an M18 Brass Plain Washer means opting for reliability and functionality.

Manufacturing Process and Quality Control

At Nafees Metal Industries, the M18 Brass Plain Washer is produced through a controlled, quality-driven manufacturing process that ensures consistency and performance in every unit. We start by sourcing certified brass sheets that are precision-cut to meet the dimensional specifications required for an M18 Brass Plain Washer.

Using high-tonnage power press machines, each M18 Brass Plain Washer is stamped and then passed through a series of secondary operations like deburring and polishing. This ensures smooth edges and a clean finish, preventing damage to adjoining components during assembly.

Our in-house inspection team conducts multiple checks on the M18 Brass Plain Washer, including diameter verification, thickness measurement, and surface uniformity. For clients with specific needs, we offer customization in thickness, outer diameter, and finishing options — making the M18 Brass Plain Washer suitable for diverse industrial environments.

The M18 Brass Plain Washer is finished with optional coatings such as clear lacquer, electroplating, or matte polish, depending on client requirements. We follow DIN 125 / IS 2016 and ISO 7089 standards, ensuring that every M18 Brass Plain Washer we produce upholds global manufacturing benchmarks.

With bulk readiness, custom packaging options, and a streamlined supply chain, Nafees Metal Industries ensures timely delivery and exceptional quality for every M18 Brass Plain Washer you order.
