Our nuts don't show their age!

Our nuts impress with their endurance and quality, even under extreme conditions.

Not without reason:

Quality assurance and improvement are two essential components of our company philosophy.
Our company processes and products are regularly tested and certified since many decades.

The surface coating is carried out by third parties. Here we rely on excellent, long-term supplier relationships that also meet our high quality requirements.

Back in 1992 we have decided to install a quality management system according to DIN EN ISO 9001. This means we can guarantee you a consistently high quality standard.

We create, promote and maintain the necessary quality awareness among our employees through appropriate information and training. We have anchored quality responsibility in all relevant areas through self-assessment and do not just rely on subsequent testing.

Our commitment

We guarantee you products of the highest quality. These products are manufactured in accordance with national and international standards. Initial Sample Test Reports (in German: EMPB) according to VDA-standards (Association of the Automotive Industry) are also available. Here you can choose between the PPF process (production process and product release) or the PPAP process (production part approval process). These processes ensure that both the production processes and the end products meet strict requirements.

As part of the PPF or PPAP process, documentation is created that describes the entire manufacturing process in detail. This ensures that every step of production is carried out properly and the products meet the required quality standards. An IMDS (International Material Data System) entry is also created to ensure that all materials used meet the necessary environmental requirements.

We focus on transparency, quality and compliance with industry standards. Providing products in accordance with VDA-standards under the PPF or PPAP process underlines our commitment to first-class products and the highest level of customer satisfaction.

Approvals

Regarding our many years of experience and high level of specialization, our nuts are already approved for many markets and industries.
