Standard bolts

DIV has more than 40 years of acquired knowledge and experience in fasteners production, built into each of our product.

Being a competitive producer of standard bolts in the EU, means controlling the entire production and supply chain circle from raw material procurement to its preparation, including PPAP level of production process monitoring ensuring that our final products meet the strictest quality requirements and provide maximum installation safety to our customers.

For high quality products, DIV uses the best in class MnB steel grade rod wire, which have the advantage of high tensile strengths in combination with high impact strengths, thus being able to offer own production of preloaded and non-preloaded structural bolting assemblies according to EN 14399 and EN 15048.

DIV is specialized in mass production of hexagonal bolts (according to DIN 931 / ISO 4014 and DIN 933 / ISO 4017) and socket cap screws (according to DIN 912 / ISO 4762),  both available in 8.8 and 10.9 grades and with different zinc finishing like electrolytic galvanizing and hot dip galvanizing

Production runs on new modern cold heading multi-stroke machines, with capacities of over 3.000 t/month, including three state of the art heat treatment production lines with controlled atmosphere and a completely automatic process right through to the final product.

Depending on customer requirements we can offer galvanic zinc protection with normal or thick layer passivation with up to 240 h durability in a salt spray test, including hot dip galvanizing intended for the most demanding outdoor use of fasteners.

Quality control is performed in-house in the new and modern laboratory for testing the mechanical properties of metallic materials and fasteners.
