Description
M8 threaded insert type 28/15 stainless steel A2 for PV profiles

Threaded insert type 28/15 is a compact fastening element designed for secure fixing in mounting profiles of photovoltaic systems. The rectangular plate with a central thread and sharp edges is slid into the groove of the aluminium profile, where it locks firmly in the channel once the bolt is tightened. Made of grade A2 stainless steel, it guarantees years of outdoor operation without loss of mechanical properties — even in environments exposed to heavy rainfall and variable temperatures. This element is ideal for fixing clamps, module brackets and other installation accessories to standard aluminium profiles used in the PV industry.
Benefits for the installer
- Quick installation — simply slide the plate into the profile groove and tighten the bolt, no special tools required
- Secure locking in the channel thanks to sharp edges that prevent the element from rotating during tightening
- Durability in outdoor conditions — non-magnetic austenitic steel resistant to corrosion in any climate
- Universal bolted connection compatible with commonly available fasteners in the photovoltaic industry
- Low weight, making storage and transport of large batches to the construction site easier
