Threaded along the entire length of the shank | Strength class 8.8 | Zinc coating | Available diameters M6–M30
The hexagon head bolt compliant with DIN 933, also referred to as PN-EN ISO 4017, is a steel fastener with a thread running the full length of the shank. It is designed for creating permanent, detachable bolted joints using nuts, washers and components with suitably prepared holes or threaded sockets.
The bolt is manufactured to strength class 8.8, making it suitable for connections requiring increased mechanical strength. The galvanised surface provides basic protection against corrosion under typical conditions of use, transport and storage.
The full thread allows for flexible positioning of the nut along the entire length of the bolt and facilitates the assembly of components of varying thicknesses. The product is suitable for use in steel structures, machinery, industrial equipment, technical installations, and workshop and maintenance work. Available diameters range from M6 to M30.

All dimensions are given in millimetres. S denotes the overall length, k the head height, and a max. the maximum length of the section without a full thread profile at the end of the screw.
Before purchasing, select the screw diameter and length to suit the thickness of the components to be joined, and check that the thread is compatible with the nut or threaded hole. In environments with high humidity, where there is contact with chemicals, or for outdoor use, it is advisable to consider fasteners with higher corrosion resistance.
