Special screws from OEB : cold extrusion parts, turned and milled parts, recutting of screws, reduced shank screws, micro screws, heavy screws – various dimensions, materials, head shapes and other specifications can be realized on request.
OEB Special Fasteners according to international standards – and also beyond the standard limits
OEB special screws are used in a wide variety of environments, e.g. in flange connections for pipelines and in hydraulic cylinders. Photo credit: sergeyryzhov und cherezoff (iStock)
Special Fasteners for your individual requirements
You need special Fasteners that are not listed anywhere, because they haven´t been produced yet? You want to flexibly combine some of these requirements in one (new) type of fastening:
- Smaller or bigger diameters and thread sizes
- Specific lengths and thread lengths
- A specific head type combined with a specific drive
- Specific hardness classes or alloy steels
- … or even more qualities or specifications
We manufacture and supply special fasteners for these industries, among others:

Otto Eichhoff GmbH & Co. KG (OEB) in Lüdenscheid/Germany has been a special screw manufacturer for over 100 years. During this time, we have built up a wealth of know-how in the field of fastening technology and, in parallel, a comprehensive knowledge of the market and the relevant industry. In the field of standard screws we are wholesalers. Our market continuity gives you maximum safety for your projects!
Special screws from OEB – Turned parts, Milled parts, Cold forged items, machined screws
There are different ways to produce special screws. Here are some examples of OEB custom bolts:
We believe: The dialogue is becoming more and more important in technical innovations!
In the beginning there is always the idea.
The sharing of ideas among several specialists is the number one factor for success, especially in view of increasing technical complexity! In other words: When smart minds talk to each other, that is still the highest level of communication!
The professional conversation in due time
- assists with feasibility studies/manufacturability analysis
- saves time in finding solutions
- gives you the security to make the right technical and at the same time economical decision
Available from us: Initial sampling according to VDA, PPAP, etc. for customer-specific articles in smaller and larger quantities
Fasteners are three-dimensional – at least!
Fastening technology depends on an extremely large number of parameters, and there is a wide variety of solutions that can hardly be surveyed.
That is why we recommend that you involve us as a solution provider as early in the planning and design phase.
Whether products are simpler and less expensive or more complex and demanding – the connectivity is often affected as well. This opens up further opportunities for product optimization. We would be happy to contribute our know-how at this ” gateway “!
Therefore: We are looking forward to your questions, we are looking forward to new challenges and we are proud if we could support our valued customers effectively!
