Description
Dromet PSRe M16x170/48 galvanised ring expansion anchor
The PSRe M16x170/48 ring expansion anchor by Dromet is a steel mechanical fastener designed for the permanent fixing of profiles, metal structures, grates, railings, machinery and other equipment items to concrete substrates. Thanks to its ring-shaped design with nut and washer, it ensures reliable load transfer in non-cracked concrete from min. class B20 (C16/20), dense natural stone and solid brick.
The anchor holds European Technical Approval ETA 05/0242, CE certificate and national approval AT-15-7574/2008, confirming its compliance with safety requirements and allowing its use in critical structural connections. The electrolytic zinc anti-corrosion coating protects the fastener against corrosion in indoor and moderately damp conditions.

The installation diagram shows a cross-section of the anchor set in a concrete substrate. The markings in the drawing correspond to the key installation dimensions: M – thread diameter, L – total anchor length, F – embedment depth in the substrate, E – thickness of the fixed element (protruding section), D – depth of the drilled hole, H – diameter of the mounting hole.
Installation recommendations
- Drill the mounting hole perpendicular to the substrate surface and clean it thoroughly of dust
- Insert the fastener into the hole using light hammer taps
- Carry out installation using a torque wrench — this guarantees the correct tightening torque
- After the anchor has expanded, the washer under the nut should be firmly pressed against the fixed element
- The parameters specified in Technical Approval AT-15-7574/2008 must not be exceeded
Application in photovoltaic installations: The PSRe M16 ring anchor performs excellently when fixing PV panel support structures to concrete foundations, footings and strip foundations. The M16 thread provides high connection load capacity, essential for wind loads acting on ground-mounted installations and flat-roof systems.
