What are DIN 7989 A4 Stainless Steel Washers?
DIN 7989 washers are heavy-duty metric flat washers designed for structural fastening applications in steel, wood, and other construction materials. Their robust design provides a larger bearing surface to distribute clamping force, making them suitable for demanding bolted connections where increased load distribution is important.
What material are DIN 7989 Washers made from?
These washers are manufactured from A4 stainless steel, also known as AISI 316 stainless steel. A4 provides excellent corrosion resistance, particularly in marine, coastal, and other harsh environments where exposure to moisture, salt, and chlorides can make standard stainless steel less suitable.
Why choose DIN 7989 A4 Heavy Duty Washers?
The heavy-duty washer profile distributes bolt and nut loads over a larger surface area, helping reduce indentation and localized stress in steel, timber, and other construction materials. A4 stainless steel adds enhanced corrosion resistance, making these washers well suited for structural and outdoor applications in demanding environments.
Where are DIN 7989 A4 Stainless Steel Washers commonly used?
Typical applications include marine and coastal construction, steel structures, timber construction, docks, boats and yachts, outdoor structures, agricultural equipment, industrial machinery, architectural installations, and other applications requiring heavy-duty metric washers with excellent corrosion resistance.
