Why Choose A4 Stainless Steel Lock Washers?
Our A4 stainless steel lock washers at AlbanyCountyFasteners.com, also known as A4 metric lock washers, are split ring washers crafted from A4 stainless steel (equivalent to 316 stainless steel, with 16-18% chromium, 10-14% nickel, and 2-3% molybdenum). These washers provide superior corrosion resistance, making them ideal for marine and highly corrosive environments. Designed to prevent loosening of bolts or screws, they exert spring-like tension in high-vibration applications, ensuring a secure assembly. Available in metric sizes like M4, M6, M10, up to M14, they meet DIN 127B, ASME B18.21.1, IFI tolerances, REACH, and RoHS standards. Their robust design makes them perfect for marine, chemical processing, and outdoor projects requiring reliable fastening and durability.
- Superior Corrosion Resistance: A4 stainless steel excels in marine and harsh environments.
- Vibration Resistance: Split ring design provides spring tension to prevent loosening.
- Metric Compatibility: Sized for metric bolts and screws for a precise fit.
- High Standards: Compliant with DIN 127B and ASME B18.21.1 for performance.
Applications for A4 Stainless Steel Lock Washers
A4 metric lock washers are designed to enhance fastening security with metric bolts or screws, preventing loosening in high-vibration or corrosive environments. Their versatility makes them suitable for:
- Marine and coastal equipment
- Chemical and food processing systems
- Outdoor construction and infrastructure

Frequently Asked Questions (FAQ)
A4 stainless steel lock washers are split ring washers made from corrosion-resistant A4 stainless steel, designed to prevent loosening of metric bolts or screws in high-vibration applications.
How do A4 stainless steel lock washers differ from A2 stainless steel lock washers?A4 stainless steel lock washers contain molybdenum for superior corrosion resistance in marine and harsh environments, while A2 stainless steel lock washers are better suited for mildly corrosive settings.
Are A4 stainless steel lock washers suitable for marine environments?Yes, A4 stainless steel lock washers are ideal for marine environments due to their excellent corrosion resistance, particularly against saltwater exposure.
How do I install A4 stainless steel lock washers?Place the washer on the metric bolt or screw with the split ends facing up, then thread the nut or fastener, tightening with a wrench to compress the washer and secure the assembly.
How do I choose the right size A4 stainless steel lock washer?Select based on the bolt’s diameter, such as M4, M6, or M10. Ensure the washer’s inner diameter matches the bolt for proper fit and tension.
