Anping County Boli Hardware Wiremesh Products Factory, established in 1998, is a professional manufacturer specializing in precision spring washers. Our Crest-to-Crest Wave Spring Washer in 304 stainless steel, with a 12mm inner diameter, 25mm outer diameter, and 0.6mm thickness, offers reliable axial load performance in compact spaces. Designed for applications requiring consistent spring force and minimal height, this washer combines durability with corrosion resistance, making it a preferred choice for engineers worldwide.
The wave spring washer features a unique crest-to-crest design, which provides a higher load capacity compared to conventional wave washers of the same dimensions. Its 304 stainless steel construction ensures excellent resistance to rust, chemicals, and temperature variations, extending service life in demanding environments. Whether used in automotive assemblies, industrial machinery, or electronic components, this washer delivers consistent performance and reduces assembly space.
Key Features & Technical Specifications
- Material: 304 Stainless Steel (1.4301) – high corrosion resistance, suitable for harsh environments
- Design: Crest-to-crest wave form – optimizes load distribution and reduces stress concentration
- Dimensions: ID 12mm, OD 25mm, Thickness 0.6mm – compact size for tight assemblies
- Load Capacity: Provides moderate axial spring force – ideal for preload applications
- Operating Temperature: -200°C to +800°C (depending on environment) – excellent thermal stability
- Surface Finish: Natural mill finish – clean and free of burrs
- Standard Compliance: Manufactured according to industry tolerances – dimensions can be customized upon request
- Packaging: Bulk or individual packaging – available as per customer requirement

Product Advantages
- Space Saving: The crest-to-crest design allows for a lower installation height compared to coil springs, reducing overall assembly size.
- Consistent Force: Provides a predictable spring rate over a wide deflection range, ensuring reliable preload in bolted joints.
- Corrosion Resistance: 304 stainless steel naturally resists oxidation and many chemicals, making it suitable for outdoor, marine, and food processing environments.
- Customizable: We can adjust dimensions, thickness, and material upon request to meet specific application requirements.
- Cost-Effective: As a manufacturer with over 25 years of experience, we offer competitive pricing without compromising quality.
- Versatile Applications: Ideal for use in automotive transmissions, hydraulic pumps, valve assemblies, electrical connectors, and precision instruments.
Our wave spring washers undergo strict quality control during production, including dimensional inspection and load testing. Each batch is traceable, and we maintain tight tolerances to ensure interchangeability. The 12mm ID / 25mm OD / 0.6mm thickness configuration is a popular size for many industrial applications, and we stock it in large quantities for fast delivery.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between crest-to-crest and crest-to-root wave springs?
A: Crest-to-crest wave springs have waves that are aligned peak-to-peak, providing a higher load capacity and more linear spring rate compared to crest-to-root designs. They are ideal for applications requiring consistent force over a small deflection range. -
Q: Can this wave spring washer be used at high temperatures?
A: 304 stainless steel can withstand continuous temperatures up to about 800°C in oxidizing environments, but actual performance depends on the application. For extreme temperatures, we recommend consulting our engineering team for custom materials. -
Q: Is the thickness of 0.6mm the wire thickness or the free height?
A: The thickness refers to the material gauge (wire thickness). The free height of the washer (undeformed) is approximately 1.2mm, which is the sum of the wave amplitude. -
Q: Do you offer other sizes or materials?
A: Yes, we can customize wave spring washers in various IDs, ODs, thicknesses, and materials such as 316 stainless steel, carbon steel, and phosphor bronze. Please provide your requirements for a quotation. -
Q: What is the typical lead time for this product?
A: For standard sizes in stock, we can ship within 3-5 working days. Custom orders typically take 10-15 working days depending on complexity. -
Q: How do you ensure the quality of the wave spring washers?
A: We perform 100% dimensional inspection using calibrated instruments, and we conduct random load testing. Our factory is ISO 9001:2015 certified (available upon request) and we follow strict quality control procedures. -
Q: Can I get a sample before placing a bulk order?
A: Absolutely. We offer free samples for standard sizes (customer pays shipping). For custom samples, a small tooling fee may apply. -
Q: What payment terms do you accept?
A: We accept T/T, L/C, and for small orders, PayPal or Western Union. Terms are negotiable for long-term partnerships.
