Metric DIN 125a A4 (316) Stainless Steel Flat Washer
Metric DIN 125a A4 (316) Stainless Steel Flat Washer: Maximum Corrosion Resistance for Harsh Environments
The Metric DIN 125a A4 Stainless Steel Flat Washer is designed for demanding applications where exceptional corrosion resistance and long-term durability are critical. Manufactured to DIN 125a standards and made from A4 (316) stainless steel, this washer provides a reliable, high-performance solution for marine, chemical, coastal, and industrial environments.
A4 stainless steel—also known as 316 stainless steel—contains molybdenum, which significantly improves resistance to saltwater, chlorides, and aggressive chemicals, outperforming standard A2 (304) stainless steel. This makes the DIN 125a A4 washer the top choice for installations exposed to moisture, acidic conditions, or high humidity.
Used in conjunction with metric bolts, screws, and threaded fasteners, this flat washer distributes load evenly and prevents damage to connected surfaces. Its smooth, flat surface enhances joint stability while reducing the risk of pull-through in softer materials.
Whether you're building offshore structures, maintaining marine vessels, assembling chemical processing equipment, or working in food-grade facilities, the DIN 125a A4 washer delivers dependable strength and superior corrosion protection.
