Roofing screw 5.5x32 zinc (pack 60 pcs) box STROYMETIZ 2070234

Roofing screws are used to fasten roofing materials to wooden battens and metal structures. The rubber-metal washer serves for waterproofing the fastening and is resistant to temperature fluctuations while maintaining integrity under direct sunlight. The hexagonal head allows for easy tightening of the fastener using a screwdriver, preventing misalignment and stripping of the head's drive surfaces. The roofing screw is protected from corrosion by an external zinc layer. The special shape and presence of a spiral notch (like a drill bit) allow such screws to securely fasten different materials together, including metal sheets.
