DIN / EN / ISO
We manufacture everything for you - whether according to European or international standard!
Based on DIN and ISO standard which provides a uniform worldwide standard, ASO Schrauben offers you a comprehensive range of standard and special fasteners according to DIN, EN and ISO and ANSI standards. When manufacturing special fasteners and custom turned parts, we therefore orient ourselves both to the German guideline and to the European and international standard.
ANSI
Successful symbiosis: US standards meet German quality.
ANSI stands for the American body for standardizing industrial procedures. We at ASO Schrauben, experts in special screws and custom turned parts, not only manufacture fasteners according to DIN, EN and ISO standards, but also according to ANSI, the proven recommendations from America.
You can look forward to products “Made in Germany”: TÜV-tested quality, on-time delivery dates
and flexibility for small orders – even if you place an order with us at short notice!
Machining production
This process is primarily used when specific dimensions must be considered to and drawing parts that deviate from the standard must be manufactured. This allows the production of small quantities to be realized. We primarily rely on a combination of machining and forming processes for the production of fasteners and bolts.
Thread rolling as a forming technology
Thread rolling is primarily used when high-strength, durable threads with optimum grain flow and corresponding surface finish are required. At ASO Schrauben, we specifically combine this process with machining processes to economically and precisely manufacture special screws with customer-specific dimensions.
Quality management
Rely on the certified and above-average quality management of ASO Schrauben. Before your workpieces leave our factory, an intensive acceptance test is carried out to ensure the level corresponding to the quality class. On request, we can provide you with test certificates and reports.
ASO Schrauben is a supplier of fasteners in the nuclear sector for one of the largest pump manufacturers in Europe. The screws are used, among other things, in pump systems for cooling circuits and high-pressure applications in nuclear facilities. They guarantee maximum stability, fatigue strength and safety in continuous operation.
