Cap nuts, also known as acorn nuts or dome nuts, are fasteners with a closed, dome-shaped end that covers the exposed threads of a bolt or screw. This design protects the threads from damage and corrosion and provides a safer, smoother finish to the assembled surface, reducing the risk of scratches or injuries.
Cap nuts are used primarily for their aesthetic and safety benefits. They are often seen in automotive, furniture, and architectural applications where the exposed end of a fastener needs to be covered for a neat appearance or to prevent physical contact with the thread ends. They are also used in machinery and electronics for similar reasons, ensuring functionality and a polished look.
Choosing the right cap nut involves several important considerations, including material, size, compatibility, and adherence to standards. Common materials for cap nuts include stainless steel, steel, and brass, each offering varying levels of strength and corrosion resistance suitable for different environments. Ensuring the size of the cap nut matches the diameter and thread pitch of the bolt or screw it is intended to secure is crucial for proper fit and function. Additionally, selecting cap nuts that conform to specific standards, such as DIN or ISO, guarantees compatibility with other compliant components, ensuring a seamless and reliable assembly.
Fabory offers a variety of cap nuts that adhere to standards like DIN 917, DIN 1587, DIN 986, ISO 4017, and ASME B18.2.3.1M. These cap nuts are made of stainless steel, steel, brass, and plastic (nylon). Available sizes range from M3 to M36 in metric and include several imperial sizes. Surface treatments include plain, zinc-plated, chrome-plated, nickel-plated, and zinc-plated black passivated, providing enhanced durability and appearance options.
