Cap nuts, also known as acorn nuts or dome nuts, are a type of fastener characterized by their rounded top and internal threading. They are typically used in applications where a finished appearance is desired, as their design covers the end of a screw or bolt. The rounded shape also serves to protect the exposed threads from damage and prevent debris from entering the fastener.
Cap nuts are made from various materials, such as steel, stainless steel, or plastic, and can come in different sizes and thread patterns to fit specific applications. They are commonly used in furniture assembly, automotive applications, and anywhere a neat appearance and protection for fasteners are needed.

Our portfolio is already vast with its more than 50,000 standard fasteners- good to know that our online catalogue and our employees‘ know-how keep the overview. But since norms cannot meet all requirements, our programme of products goes beyond DIN data sheets and factory recommendations: special productions according to drawings- from the special type of screws to the plate bending part- complete our offer. We have our own innovations in our programme of products as well. One of our specialties are magnetic plug systems.
They collect the abrasion in gearbox cases or serve as a specially constructed fuel level plunger in wind power stations. In addition we have been involved in further developments of suspension arrangements in the field of mining and tunnel construction. Besides we offer extended screws for which there was a special annex to the DIN norms for the open line construction. A cleverly devised and software-supported stock-keeping and assignment sale make sure that our products are also delivered to you as soon as possible and in a perfectly compiled manner.
