DIN 917 Low Cap Nut, Hexagon, Zinc-Plated

The low hexagon cap nut DIN 917 is used in machine tool building, mechanical engineering, instrument manufacturing and other industrial sectors. The nut’s design covers the thread with a cap, protecting it from dust and moisture and giving the joint a neat appearance.

Design and materials

The cap covers the thread from the inside, preventing contamination and improving the sealing of the assembly, while also concealing the protruding end of the bolt or screw. DIN 917 nuts are made of stainless steel, carbon steel or brass. The zinc-plated version provides corrosion resistance. Stainless nuts are resistant to aggressive environments.

Applications

DIN 917 nuts are used in machine-building workshops, equipment manufacturing, furniture assembly and other areas where reliable mounting and a neat joint appearance are required. The low profile and smooth surface simplify installation and ensure a tight fit between parts. The nuts withstand mechanical and vibration loads.
