Description
Dromet ring anchor expansion bolt PSRe M16x170/48 galvanised
The PSRe M16x170/48 ring anchor expansion bolt by Dromet is a steel mechanical fastener designed for permanent fixing of profiles, metal structures, gratings, railings, machinery and other equipment elements in concrete substrates. Thanks to its ring construction with nut and washer, it ensures reliable load transfer in non-cracked concrete from class min. B20 (C16/20), dense natural stone and solid brick.
The anchor holds a European Technical Assessment 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 corrosion protection safeguards the fastener against corrosion in internal and moderately damp conditions.

The installation diagram shows a cross-section of the anchor embedded in a concrete substrate. The markings on the drawing correspond to key installation dimensions: M – thread diameter, L – overall anchor length, F – embedment depth in the substrate, E – fixture thickness (protruding section), D – depth of the drilled hole, H – installation hole diameter.
Installation recommendations
- Drill the installation hole perpendicular to the substrate surface and clean it thoroughly of dust
- Insert the fastener into the hole using light hammer taps
- Perform installation using a torque wrench — this guarantees 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 the Technical Approval AT-15-7574/2008 must not be exceeded
Application in photovoltaic installations: The PSRe M16 ring anchor performs excellently when fixing support structures for PV panels 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.
