SS Dome Nut

Stainless steel dome nuts per DIN 1587 are hexagonal cap nuts with a closed domed end that encloses the bolt thread. They provide thread protection, personnel safety, and a finished appearance in visible fastening locations across furniture, automotive, and architectural applications.

Dimension #

• All dimensions in mm, tolerance +/- 0.01 mm. Additional dimensions available on request.

Benefits #

Dome nuts address the engineering need for thread end protection in exposed fastening locations. The closed domed cap seals bolt ends from moisture, chemicals, and particulate contamination, preventing thread corrosion that can make future disassembly difficult. In safety-critical applications, the smooth dome eliminates sharp exposed thread ends that can cause injury or snag on clothing and equipment. For hygienic environments in food processing and pharmaceutical equipment, the seamless dome surface is easy to clean and resists bacterial accumulation. The A2 and A4 stainless steel construction provides corrosion resistance without additional coatings, reducing maintenance requirements. Dome nuts also deliver a clean, finished appearance in architectural and furniture applications where visible fastener aesthetics matter.

Common Applications #

Stainless steel dome nuts are specified where thread protection, safety, or appearance are design priorities.
