Description
Dromet – PSRe M8x155/85 galvanised ring expansion anchor
The PSRe M8x155/85 ring expansion anchor from Dromet is a reliable mechanical fastening component designed for permanent anchoring of structures in concrete substrates. It performs well wherever a secure, certified connection is required — from installing profiles and support structures for photovoltaic systems, to fixing grates, balustrades and handrails, to anchoring machinery and equipment in industrial facilities.
Construction and material
The anchor has a ring-shaped design — once the nut is tightened with a torque wrench, the cone expands the rings, ensuring a strong grip against the hole wall. The set includes an M8 nut and a washer. The fastener is made of structural steel with corrosion protection in the form of electrolytic zinc plating, guaranteeing durability under typical construction site conditions.
Certificates and approvals
The anchor holds a European Technical Approval ETA 05/0242 and a CE certificate, and is also covered by national approval AT-15-7574/2008. This means it can be used in projects requiring documented load capacity and compliance with standards — which is particularly important for photovoltaic installations and steel structures subject to technical inspections.

Installation recommendations
The mounting hole must be drilled perpendicular to the substrate surface and then thoroughly cleaned of drilling dust. The fastener should be able to be inserted into the hole with light hammer taps. Installation must be carried out using a torque wrench — once the anchor has expanded, the washer under the nut must be firmly pressed against the fixed element. All permissible loads and installation distances are set out in Technical Approval AT-15-7574/2008 — the parameters specified therein must not be exceeded.
Thanks to its compact dimensions, low weight and full certification, the Dromet PSRe M8x155/85 anchor is an economical and proven solution for professional installation teams carrying out both PV installations and general construction anchoring work.
