Ultimate Guide to Stainless Steel Washers – Grades, Types, Uses & Top Suppliers
Stainless steel washers may be small, but they play a crucial role in ensuring the strength, safety, and durability of mechanical and structural assemblies. Whether you’re working in construction, automotive, marine, or manufacturing, choosing the right type and grade of stainless steel washer is essential.
In this guide, we’ll explore the different grades, types, uses, and top suppliers of stainless steel washers, helping you make informed decisions for your projects.
What Are Stainless Steel Washers?
A stainless steel washer is a thin, typically round metal disc with a hole in the centre. It’s used to distribute the load of a threaded fastener, reduce vibration, prevent loosening, and protect the surface underneath.
Unlike regular washers, SS washers offer superior corrosion resistance, making them ideal for harsh environments.
Common Grades of Stainless Steel Washers
Choosing the right grade depends on the application, environmental exposure, and mechanical strength required.
1. 304 Stainless Steel
- Most commonly used grade
- Excellent corrosion resistance
- Suitable for general-purpose use in dry indoor conditions
Cost-effective and widely available
2. 316 Stainless Steel
- Higher corrosion resistance than 304
- Contains molybdenum for enhanced strength
- Best for marine, chemical, and saltwater environments
- Slightly more expensive but long-lasting
3. 410 Stainless Steel
- High strength and hardness
- Moderate corrosion resistance
Ideal for high-stress applications (less used in marine or wet areas)
Types of Stainless Steel Washers
Washers come in a variety of designs to suit specific functions:
• Flat Washers
The most common type is used to distribute load evenly across surfaces.
• Spring Washers
Also known as split or lock washers, used to prevent nuts and bolts from loosening due to vibration.
• Fender Washers
Larger outer diameter than flat washers — used to spread load over larger surfaces.
• Dome Washers / Countersunk Washers
Used in precision applications for a sleek finish and even pressure distribution.
Applications: What Are Stainless Steel Washers Used For?
Stainless steel washers are versatile and used across industries, including:
- Construction: Load distribution and structural stability
- Automotive & Machinery: Withstand high stress and vibration
- Marine Industry: Ideal due to their rust-resistant properties
- Electrical Equipment: Offer insulation and surface protection
Oil & Gas / Chemical Plants: Withstand corrosive environments

FAQ
Stainless steel washers are used to distribute the load of a threaded fastener like a bolt or screw. They help prevent surface damage, reduce vibration, and keep fasteners secure. Due to their corrosion resistance, they are ideal for use in construction, automotive, marine, and industrial environments.
The main difference lies in corrosion resistance. 316 stainless steel washers contain molybdenum, making them more resistant to saltwater and harsh chemicals than 304 washers. While 304 is cost-effective for general use, 316 is better suited for marine or chemical applications.
The price of stainless steel washers varies based on the grade and size. On average:
- 304 SS washers cost around ₹180–₹220 per kg
316 SS washers range from ₹250–₹300 per kg
Custom specifications, finishes, and bulk orders can affect pricing.
