Why Choose A4 Stainless Steel Flat Washers?

Our A4 stainless steel flat washers at AlbanyCountyFasteners.com, also known as A4 metric flat washers, are flat, circular washers crafted from A4 stainless steel (equivalent to 316 stainless steel, with 16-18% chromium, 10-14% nickel, and 2-3% molybdenum). These washers distribute the load of metric bolts or screws, protect surfaces from damage, and ensure a secure fastening. Offering superior corrosion resistance, they are ideal for marine and highly corrosive environments. Available in metric sizes like M4, M6, M10, up to M14, they meet DIN 125A, ASME B18.22.1, IFI tolerances, REACH, and RoHS standards, making them perfect for marine, chemical processing, and outdoor projects requiring durability and reliability.

  • Superior Corrosion Resistance: A4 stainless steel excels in marine and harsh environments.
  • Load Distribution: Spreads fastener load to prevent surface damage.
  • Metric Compatibility: Sized for metric bolts and screws for a precise fit.
  • High Standards: Compliant with DIN 125A and ASME B18.22.1 for performance.

Applications for A4 Stainless Steel Flat Washers

A4 metric flat washers are designed to enhance fastening with metric bolts or screws, providing load distribution and corrosion resistance in demanding environments. Their versatility makes them suitable for:

  • Marine and coastal structures
  • Chemical and food processing equipment
  • Outdoor construction and infrastructure
  • Automotive and industrial assemblies

Frequently Asked Questions (FAQ)

What are A4 stainless steel flat washers?

A4 stainless steel flat washers are flat, circular washers made from corrosion-resistant A4 stainless steel, designed to distribute the load of metric bolts or screws and protect surfaces.

How do A4 stainless steel flat washers differ from A2 stainless steel flat washers?

A4 stainless steel flat washers contain molybdenum for superior corrosion resistance in marine and harsh environments, while A2 stainless steel flat washers are suited for mildly corrosive settings.

Are A4 stainless steel flat washers suitable for marine environments?

Yes, A4 stainless steel flat washers are ideal for marine environments due to their excellent corrosion resistance, particularly against saltwater exposure.

How do I install A4 stainless steel flat washers?

Place the washer on the metric bolt or screw before threading the nut or fastener, then tighten with a wrench to ensure even load distribution and a secure assembly.

How do I choose the right size A4 stainless steel flat washer?

Select based on the bolt’s diameter, such as M4, M6, or M10. Ensure the washer’s inner diameter matches the bolt and the outer diameter suits the application for proper load distribution.
