What is an M16 Brass Plain Washer?

An M16 Brass Plain Washer is a circular, flat metallic disc with a central hole designed to fit M16 bolts or screws (16 mm in diameter). These washers are essential components in fastening systems, primarily used to distribute the load of the bolt evenly across the surface, prevent material deformation, and protect the substrate from damage.

The use of brass gives the washer superior mechanical, electrical, and anti-corrosive properties, making it highly suitable for industrial applications that require conductivity, resistance to water or chemicals, and long-term durability.

Each M16 Brass Plain Washer produced by Nafees Metal Industries is manufactured to industry standards like IS 2016 and DIN 125, ensuring consistent quality, performance, and dimensional accuracy.

Key highlights of this washer include:

• Inner Diameter: ~17 mm (fits M16 fasteners with precision)

• Outer Diameter: As per DIN 125 standard

• Material: High-quality brass alloy (usually conforming to IS 319 or equivalent)

• Thickness: Typically ranges between 1.5 mm to 3 mm (custom sizes available)

Whether used in electrical installations, marine assemblies, or plumbing hardware, the M16 Brass Plain Washer plays a vital role in delivering secure, vibration-resistant fastening.

Why Choose Brass for M16 Plain Washers?

Brass is a premium non-ferrous alloy composed primarily of copper and zinc. It offers a unique combination of properties that make it ideal for washers used in mechanical, electrical, and decorative applications. When it comes to M16 Plain Washers, brass stands out as a material of choice due to the following reasons:

1. Excellent Corrosion Resistance

Brass naturally resists corrosion from moisture, chemicals, and air, making it perfect for indoor and outdoor use, especially in marine, plumbing, and electrical installations where other metals may rust or degrade.

2. Superior Electrical Conductivity

For electrical components and connections, conductivity is key. Brass offers high electrical conductivity, which ensures efficient performance in grounding and power transfer applications.

3. Non-Magnetic & Spark-Resistant

Brass is non-ferrous and non-magnetic, which is crucial in electronic and sensitive instrumentation. It also prevents sparking, making the M16 Brass Plain Washer suitable for use in explosive or flammable environments.

4. Wear Resistance

Thanks to its hardness and smooth finish, brass provides resistance to wear and deformation, maintaining its integrity even under mechanical stress and repeated tightening.

5. Aesthetic Appeal

Brass has a natural golden finish, which is desirable in applications where both functionality and appearance matter – such as fittings, panels, exposed assemblies, and luxury hardware.

6. Dimensional Stability

Brass holds tolerances well even at large diameters, ensuring perfect alignment, accurate fitment, and long-lasting joint strength.

7. Recyclability

Brass is an environmentally responsible material – it is 100% recyclable without any loss of quality. Choosing M16 Brass Plain Washers supports sustainable manufacturing practices.

How Are M16 Brass Plain Washers Manufactured?

At Nafees Metal Industries, we follow a highly controlled and precision-oriented manufacturing process to produce M16 Brass Plain Washers. Our production line is ISO-certified and equipped with high-speed machinery, skilled operators, and rigorous quality controls to ensure consistency and excellence in every washer.

Below is a step-by-step overview of our manufacturing process:

Customers can choose from a variety of surface treatments based on their functional or aesthetic requirements. We offer:

• Natural polished brass finish

• Nickel plating

• Chrome plating

• Custom coatings upon request

These finishes enhance corrosion resistance, improve appearance, and increase service life.

5. Dimensional Inspection & Quality Testing

Each batch of M16 Brass Plain Washers undergoes rigorous testing for:

• Inner and Outer Diameter Tolerance

• Thickness Consistency

• Flatness and Concentricity

• Surface Finish and Coating Adhesion

Our in-house QA team follows national and international quality protocols to ensure defect-free, high-performance washers.

6. Packaging and Labeling

We offer bulk and custom packaging options to suit different business needs:
