Product Description
M4 x 0.7mm - Domed Hex Nuts DIN 1587 - A2 Stainless Steel | Vital Parts
Our Domed Hex Nuts, also known as Acorn Nuts, are designed to provide a secure and visually appealing fastening solution. These nuts feature a closed-end dome that protects exposed threads, preventing damage and reducing the risk of injury from sharp edges. Manufactured to DIN 1587 standards, they are commonly used in conjunction with bolts and machine screws to fasten and secure components across various applications.
What are Domed Hex Nuts?
Domed Hex Nuts, also called Acorn Nuts or Cap Nuts, are a type of hex nut featuring a rounded dome on one end. Unlike standard hex nuts, they are not fully threaded, providing additional protection to the fastening assembly. The dome acts as a barrier, preventing external contaminants such as moisture, dust, and debris from entering the thread, which can extend the lifespan of the fastener.
These nuts are commonly used in automotive, construction, and industrial settings where aesthetics and safety are essential. Their smooth, polished appearance makes them an excellent choice for visible installations, while their durability ensures long-lasting performance.
