When made using SS202 stainless steel, they offer enhanced strength and corrosion resistance—ideal for both indoor and outdoor industrial settings.

SS202 Washers are crafted from chromium-nickel-manganese alloy. While more economical than SS304, they still retain excellent mechanical properties. These washers offer:

• Moderate to good corrosion resistance

• High tensile strength

• Excellent formability and weldability

• Cost-effectiveness for bulk usage

Our M14 SS202 Plain Washers comply with international standards for quality and are suitable for use in automotive, construction, marine, machinery, and heavy engineering projects.

Key Features of M14 SS202 Plain Washers

The M14 SS202 Plain Washers are precision-engineered components designed to provide reliable support in mechanical assemblies. These washers serve as essential buffer elements between fasteners and surfaces, enhancing the longevity and integrity of joints. Below are the elaborated features that make them indispensable in industrial-grade applications:

1. High Corrosion Resistance

One of the most critical features of M14 SS202 Plain Washers is their exceptional resistance to corrosion. SS202 grade stainless steel contains chromium and nickel, which form a passive oxide layer that prevents rusting and degradation, even in harsh environments such as coastal or chemical-prone areas. This feature makes these washers ideal for outdoor use, construction equipment, and moisture-laden industrial environments.

2. Dimensional Accuracy and Precision

Our M14 SS202 Plain Washers are manufactured with tight tolerances and precise inner and outer diameters, ensuring a perfect fit with M14 bolts, screws, and threaded rods. The uniform thickness and symmetrical flatness maintain load distribution consistency, thereby avoiding stress concentration on one point of the assembly. This also contributes to better torque control during tightening.

3. Optimal Load Distribution

The M14 SS202 Plain Washer acts as a load-spreading device, distributing the clamping force from the fastener evenly over a broader surface. This prevents damage to the connected parts, especially softer substrates like aluminum or plastic, which may otherwise get deformed under bolt heads.

4. Minimized Surface Wear

In repeated tightening or high-vibration applications, surfaces tend to wear out. The stainless steel material and flat geometry of the M14 SS202 Plain Washers reduce friction and wear between the fastener and the work surface, improving the lifespan of both the bolt and the assembly.

5. Temperature Resistance

SS202 stainless steel has a higher resistance to temperature fluctuations compared to mild steel. M14 SS202 Plain Washers retain structural integrity in both hot and cold working conditions, making them suitable for thermally dynamic environments like boiler systems, turbines, and power plants.

6. Cost-Effective Durability

SS202 offers a cost-efficient alternative to SS304 and SS316 while still delivering strong corrosion resistance and mechanical performance. M14 SS202 Plain Washers, thus, provide excellent value for money, especially in applications where exposure to extreme corrosive agents is moderate.

7. Non-Magnetic Properties

In annealed conditions, SS202 stainless steel has low magnetic permeability. This makes M14 SS202 Plain Washers suitable for applications that require minimal electromagnetic interference, such as electrical enclosures or sensitive electronic assemblies.

8. Smooth Finish and Aesthetic Appeal

These washers are manufactured with a smooth, burr-free surface that reduces the risk of injury during handling and installation. Moreover, the clean metallic finish ensures they complement the visual appeal of the overall assembly—particularly important in architectural and exposed-joint applications.

9. Compliance with Industry Standards

Our M14 SS202 Plain Washers conform to international dimensional and mechanical standards like DIN 125, IS 2016, and ASTM, ensuring they are compatible with global equipment and fastener systems.

10. Anti-Loosening Functionality (When Combined with Other Hardware)

Though plain washers do not inherently prevent loosening, when used in conjunction with spring washers or lock nuts, M14 SS202 Plain Washers improve the overall reliability of the assembly by serving as a base for anti-loosening mechanisms.

11. Versatility in Assembly Configurations

The M14 SS202 Plain Washers are suitable for use with hex bolts, carriage bolts, threaded studs, and machine screws. They can be installed in horizontal, vertical, or angled orientations, enhancing their utility in real-world construction and machine assembly scenarios.

12. Enhanced Fatigue Resistance

The distribution of mechanical stress and vibration dampening characteristics of M14 SS202 Plain Washers contribute to enhanced fatigue resistance, minimizing the chances of mechanical failure in long-term use.

Applications of M14 SS202 Plain Washers

M14 SS202 Plain Washers are integral components in numerous industrial and mechanical environments. Their role may appear subtle at first glance, but these washers deliver critical functionality in distributing load, preventing surface damage, and enhancing the longevity of fastening systems. The combination of the M14 size and the SS202 grade stainless steel composition makes these washers an ideal choice for mid-heavy-duty applications across diverse industries. Below is a detailed analysis of where and how these washers are utilized:

1. Automotive and Heavy Vehicles

In the automotive sector, M14 SS202 Plain Washers are frequently employed in assembling engine components, mounting chassis elements, and in wheel bolt fittings. Their primary purpose is to:

• Prevent bolt loosening caused by engine vibration and road shock.
