About this item
  • High Quality Materials: Self-tapping roof screws are made of high-quality, durable 410 stainless steel, a material renowned for its excellent corrosion resistance. They offer high resistance to mechanical damage during installation, are insensitive to UV rays, and retain their colour over time, making them ideal for roofing applications.
  • Durability: Stainless steel self-drilling roof screws have built-in rubber seals that effectively prevent moisture penetration, ensuring a permanent, secure and tight connection. The seals remain elastic, protecting the screws from high temperatures and extending their service life.
  • Easy Installation:The corrugated roof fixings feature an external hex head that provides a larger contact area, making the screws easier to position and secure. No pre-drilling is required. A hex socket is included in the package to make installation and removal quicker and more convenient.
  • Versatile Applications: These trapezoidal sheet screws are suitable for fastening sheets, gutters, metal roofs, metal structures, and more. The screws with seals securely fix sheets, profiles, and metal plates to wooden substrates. The self-tapping sheet screws are highly resistant to mechanical damage, making them crucial for installation.
  • Package includes: 50 pieces of hexagonal screws, size: 5.5x25mm. Combination of the sheet screws with a seal: screw head and washer, including hexagon socket.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
