Ensure severe weather resistance across flat-roof solar frameworks with the premium Van Der Valk 775020G stainless steel self-tapping screw. Specifically engineered by Van Der Valk Solar Systems for the high-load ValkPro+ Max NextGen commercial mounting system, this heavy-duty 6.5x20mm fastener provides exceptional tensile strength when anchoring structural components, side plates, and back plates to galvanized roof carriers.

Fabricated from premium-grade AISI 304 stainless steel, the Van Der Valk 775020G features a robust SW6 hexagonal head design that prevents tool slippage during high-torque power driving. Engineered with a specialized thread-forming tip, it cuts cleanly into heavy-gauge steel profiles without requiring time-consuming pre-drilling, entirely eliminating metal shavings and reducing on-site installation times.

Designed to secure large-format solar panels against high wind shear and heavy snow loading, this corrosion-resistant hardware delivers ultimate structural longevity.
