Description
Bimetallic stainless self-drilling screw 6.0×25 mm with washer – PV and steel structure mounting
A professional bimetallic self-drilling screw 6.0×25 mm designed for fastening thin-walled steel and aluminium profiles in photovoltaic installations, roof structures and facade structures. It combines a stainless steel shank with a hardened drilling tip, meaning no pre-drilling is required — it can be driven directly into the base material. The chip-free drilling technology eliminates the formation of metal shavings on the mounting surface, effectively preventing corrosion hotspots at the connection point. The hex head with an integrated sealing washer ensures a tight fit and even pressure distribution on the sheet metal, which is crucial when mounting on roofs exposed to weather conditions.
Benefits for the professional installer
- Direct installation without pre-drilling — the hardened drilling tip shortens working time on the roof
- Chip-free drilling — no metal shavings prevents corrosion hotspots on the mounting surface
- Bimetallic construction combining shank flexibility with tip hardness — the screw does not crack under dynamic load
- Hex head with sealing washer — a tight connection resistant to weather conditions
- Designed for photovoltaic installations, roof, facade, and steel-aluminium structures
