Metal roofing fixings designed to give a weather-resistant, secure attachment for corrugated and trapezoidal metal sheets, sturiz Metal Roofing Screws. Durable zinc-plated carbon steel and EPDM sealing washers reduce leak risk and take the worry out of external repairs for tradespeople and keen DIYers. Are these fittings robust enough for long-term outdoor exposure and quick enough to save time on-site?
⚡ At a Glance
- • Weather Resistance: Triple protection from carbon steel, zinc plating and EPDM sealing washer for prolonged outdoor use.
- • Best for: Roofing contractors and DIYers fitting corrugated metal sheets who need reliable seals.
- • Not ideal for: Applications requiring stainless-steel fasteners or where exact decorative finish matching is critical.
Self-drilling 4.8 x 35 mm screws include integrated rubber sealing washers and two M8 chromium-vanadium adapter heads. External hex head design and zinc plating focus on ease of installation and corrosion resistance.
Weatherproof Seals – Thanks to EPDM sealing washers
EPDM washers sit beneath the external hex head and compress against metal sheets to form a watertight barrier while allowing for thermal expansion. The sealing system prevents moisture ingress at the fixing point.
Effective moisture exclusion reduces leak risk and cuts down on repeat maintenance after temperature changes.
Quick Installation – With self-drilling point and hex head
Self-drilling tips cut through metal without the need for pre-drilling, while the external hex head accepts high torque from wrenches or power tools. Two chromium-vanadium M8 adapter heads are included to speed power-tool use.
Faster fixings on-site reduce time spent at height and lower labour requirements.
Corrosion Protection – Thanks to zinc plating and protective coating
Carbon steel cores receive a zinc plating and a protective topcoat that resists rust and UV degradation, helping the fasteners retain roof-colour appearance. The coating also reduces damage during driving.
Longer-lasting fixings that maintain appearance and structural integrity in outdoor conditions.
✨ The 4 Key Reasons for sturiz Metal Roofing Screws
