Hexagonal bolts

The reliable connection of constructions depends upon the use of the right bolts in combination with the correct nuts.

Properties of hexagonal bolts

To ensure that we are always able to provide the appropriate quality, hexagonal bolts are available in various classes: 8.8, 10.9, 12.9 and 14.9. These classes include many different qualities of steel, stainless steel and brass, as well as a variety of processes. For example, steel bolts may be processed as follows: hot galvanised, mechanically galvanised, PTF-coated or Geomet-treated. In addition, nickel-plated brass bolts are available in several quality classes.
Most of these bolts are used within high-quality constructions, e.g. in the automotive, offshore and shipping industries. The spectrum of applications is extensive. Many bolts include a special coating, are Lloyd’s certified and meet relevant DIN and/or EN standards.

  • Hexagonal bolts available in quality Classes 4.6, 8.8, 10.9, 12.9 and 14.9
  • Available in: steel, stainless steel and brass
  • Processing: hot galvanised, mechanically galvanised, PTFE-coated or Geomet-treated

If required, we can drill a small hole at the extremity of hexagonal bolts so that a split pin can be inserted for additional securing.
