Dromet PSRe M10x170/90 galvanised ring expansion anchor

The PSRe M10x170/90 ring anchor by Dromet is a proven expansion fastener for the permanent fixing of structures in concrete, stone and brick substrates. Thanks to its ring-shaped design, it ensures a secure expansion within the mounting hole, while the nut and washer set allows for quick, controlled installation using a torque wrench.

The anchor is designed for fixing metal profiles and structures, railings, balustrades, machinery and other building equipment. It can be used with non-cracked concrete of at least class B20, natural stone with a compact structure, and solid brick — making it a versatile solution for construction sites and for mounting photovoltaic installations on façades or foundations.

Certificates and approvals

The product holds a European Technical Approval ETA 05/0242 and a CE certificate, and is also covered by the national approval AT-15-7574/2008. This confirms verified load capacity and compliance with European standards — which is particularly important when documenting installations for investors and supervising inspectors.

Technical parameters

Installation recommendations

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