Dromet PSRe M12x250/158 expansion ring anchor, galvanised

The PSRe 12×250/158 ring anchor from Dromet is a heavy-duty expansion fastener designed for the permanent fixing of metal structures, profiles, grilles, railings, machinery and building equipment components. Its ring construction with nut and washer ensures secure expansion within the hole and high load capacity — an ideal solution for installation teams working with heavy mounting components, including structures for photovoltaic installations.

The anchor is intended for installation in uncracked concrete of at least class B20, dense natural stone and solid brick. It holds a European Technical Approval ETA 05/0242, a CE certificate and a national approval AT-15-7574/2008, confirming its compliance with European and national requirements for structural applications.

Installation recommendations

The mounting hole should be drilled perpendicular to the surface of the substrate and thoroughly cleaned of drilling dust. The fastener should be able to be inserted with light hammer taps. Installation should be carried out using a torque wrench — once the fastener has expanded, the washer under the nut must be firmly pressed against the element being fixed. The parameters specified in Technical Approval AT-15-7574/2008 must not be exceeded.
