These A4 (316) Stainless Steel Dome Nuts conform to DIN 1587 and are designed for high-performance fastening where corrosion resistance and a clean, finished appearance are essential. Also known as acorn nuts, they are typically used to cap exposed threaded bolts or studs for safety, aesthetic or hygienic reasons.
Manufactured from marine-grade A4 stainless steel, these dome nuts offer outstanding resistance to rust and corrosion, making them ideal for outdoor, marine, chemical and food-grade applications. Their smooth, rounded top helps prevent thread damage and reduces the risk of snagging or injury, making them particularly suitable for environments where safety and visual appeal are priorities.
Available in a full range of metric thread sizes, these nuts are compatible with bolts and threaded rod of the same size and pitch. Perfect for applications in stainless steel fabrications, water systems, architectural fixings, and industrial machinery where durability and longevity are critical.
