DIN 931

DIN 931 screws are designed for strong fastenings in metal structures, machinery and industrial applications where a secure and removable connection is required. They feature a hexagonal head and partial thread, making them ideal for assemblies that need a smooth contact area or require greater rigidity in the screw body.

Thanks to their design in accordance with DIN 931, these screws ensure high compatibility with DIN 934 nuts and DIN 125 washers, meeting the precision and quality standards required in technical environments.

CHAVESBAO's DIN 931 screws are manufactured in accordance with the quality standards required by the professional industry. Available in steel with different mechanical qualities (8.8, 10.9 or 12.9), as well as in A2 and A4 stainless steel versions, they can be adapted to both standard industrial environments and more aggressive or outdoor conditions.

We also offer options with different finishes, such as zinc-plated, black or hot-dip galvanised, which improve corrosion resistance depending on the type of application. These combinations allow you to select the most suitable screw for each assembly, ensuring reliable tightening and a strong bond even in demanding environments.
