PEINER Umformtechnik supplies high-strength HV-bolt-sets and HV fit-bolt-sets complying with DIN EN 14399-4, DIN EN 14399-6 and DIN EN 14399-8 to the steel construction industry through the large distributors.

PEINER high-strength preloaded (HV) bolt-sets are preferably used in slip-resistant connections, flexural rigid plate connections, shear type connections and in ring flange connections of wind turbines.
As construction elements serving a safety function, these fasteners must comply with strict quality requirements. Consequently, we have installed high-precision standards and invested heavily in quality assurance.

Each PEINER HV-bolt and HV-nut carries a code – a serial number – to make the end product traceable right down to the batch of input material. This code adds transparency to the production process and, at the same time, is an expression of our quality demand.
According to DIN 18800-7:2008-11, this makes test certificates 3.1 which DIN EN 10204 requires for HV-bolts, unnecessary. However, test certificates 3.1 will still be issued on request. PEINER HV-sets are available ex stock in the standard size range from M12 to M36. Larger sizes up to M64, especially for installation in wind turbines, complying with DASt-guideline 021 and the corresponding PEINER company standard, are also available.

We also support our customers in designing specific applications of these fastener elements, the respective validation and the assistance in the application process for approval of the same.
