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.

Standards

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.

Standards

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.

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.

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.

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

Standards

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

Standards

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.
