Industries we serve

The connecting of two constructions is the common function of all the components within this group. Threaded ends, studs and stud bolts can have an impressive length of several metres.

Properties of threaded ends, studs, stud bolts and turnbuckles

We can supply threaded ends and studs in the quality Classes 4.6, 8.8, 10.9 and 12.9. Whereas threaded ends are threaded throughout, studs are only threaded at the end. A stud may be screwed into an engine block, for example, after which another part is mounted on it and secured with a nut.

Threaded ends are often cast into concrete at one end; the construction is then installed onto the protruding section and secured with a nut.

Stud bolts are threaded ends with 2 nuts. They may be used, for example, to connect 2 flanges in a pipeline carrying gas or water. In point of fact, stud bolts are threaded ends in an upgraded quality, such as B7, A320 or B8. Dedicated threaded ends are frequently used in the US and UK and for specific applications, particularly in refineries.

Turnbuckles are used to pull constructions towards one another; they come in a single quality and several types of processing.

Threaded ends and studs are available in the range from M3 to M200
We supply quality Classes 4.6, 8.8, 10.9 and 12.9
