DIN and standard parts

Other screws

These screws have specific application areas and require special tools to screw them in.

We offer screws with a variety of head shapes and driving features, as well as types with no head at all

In addition to traditional internal and external driving features, we also offer screws with alternative head shapes such as ring heads, dome heads or knurled heads.

Method and principle

Overview of other screws

Depending on the selected head geometry, the screws are screwed in manually or using special tools.


In addition to steel with different coating systems, available materials include stainless steel, brass and plastic.


Our products can be coated with different surface finishes depending on requirements and application. We will be pleased to give you individual advice on the right coating system.

We offer the following surfaces as standard:

  • Plain
  • Zinc plated (industry standard)
  • VZD (zinc plated with thick layer passivation)
  • Zinc-nickel
  • Zinc flake

Types of screws

  • Eyebolts

    Due to their special head shape, eyebolts are used as fasteners for hooks or cables, as well as guides for bars.
    They are particularly suitable for movable connections such as locking devices, fence systems or cylinders. Eyebolts are not to be confused with lifting eyebolts. These are used as load suspension devices.


    •  DIN 444
  • Cup square bolts

    Cup square bolts and carriage bolts are characterised by their button head and square neck. They are fastened using a counter-rotating nut and provide an aesthetic screw connection where the screw is protected from unwarranted loosening. They are available with or without a preinstalled nut and are often used on locks, fittings or doors.


    • DIN 603
  • Wing screws

    Due to their head shape, wing screws can be attached and loosened by hand without tools. The wing head comes in two different shapes – the American angular design and the German rounded variant. Wing screws are often used as a locking element in mechanical engineering or in gardening machines.


    • B 316
    • DIN 316
  • Knurled screws

    Knurled screws feature a grooved surface around the outside of the head. This makes it easier to tighten and loosen the screw by hand with less risk of slipping. As well as being used in areas such as household technology or industry, they are also well suited to applications in which regular fine adjustments are required.


    • DIN 464
    • DIN 653
  • Lifting eyebolts

    Thanks to their head shape, lifting eyebolts are used when lifting heavy loads. For this reason, they are generally installed permanently as load suspension devices and can also be provided with particularly large threads.


    • DIN 580
  • Countersunk nib bolts

    Countersunk nib bolts are fastened with a nut and then countersunk into the mounting material. This prevents unwarranted loosening.


    • DIN 604
  • Foundation bolts

    Foundation bolts are anchored in concrete, providing an extremely strong attachment point for machines or other construction parts.


    • DIN 529
  • Engineer studs

    Engineer studs have no head, much like threaded rods. Unlike threaded rods, they come with a shaft in the middle or at the end of the screw.


    • DIN 835
    • DIN 938
    • DIN 939
  • Square head bolts

    Square head bolts with an external driving feature can be screwed in with high torque. DIN 479 is also characterised by a short dog point at the end of the thread.


    • DIN 479
