What are DIN 7980 A4 Stainless Steel High Collar Split Lock Washers?
DIN 7980 split lock washers are metric spring washers with a high collar design and a small outer diameter for socket head cap screws. The split and slightly offset ring creates spring tension when compressed under the fastener, helping resist loosening from vibration and movement while maintaining a compact profile.
What material are DIN 7980 A4 Stainless Steel Washers made from?
These washers are manufactured from A4 stainless steel, also known as AISI 316 stainless steel. A4 provides excellent corrosion resistance in demanding environments, including applications exposed to moisture, saltwater, and chlorides.
Why choose DIN 7980 A4 High Collar Split Lock Washers?
The small outer diameter is ideal for socket head cap screws, particularly where limited clearance around the fastener makes a larger washer impractical. The high collar provides additional bearing support while the split design provides spring tension to help resist loosening.
Where are DIN 7980 A4 Stainless Steel Washers commonly used?
Typical applications include marine equipment, boats and yachts, coastal structures, outdoor machinery, automotive and motorsport equipment, pumps, industrial machinery, electrical equipment, and other applications using socket head cap screws where a compact, corrosion-resistant metric lock washer is required.
