Description:
- Bonded Washers
- For most roofing applications a washer bonded to a galvanized steel washer is the most commonly used washer for Hex head self-drilling screws. The bonded washer has stress-crack resistance, waterproof properties, and resistance to UV radiation.
- Cut Tip
- A thread cutting screw for wood with a coarse tapping screw thread and a special long sharp point fluted to capture chips.
- Flange Hexagon Head
- Provide a larger bearing surface and when used with the sealing washer it will hold the sealing washer inside making it more efficient to protect a leakage.
- Finishing
- Yellow zinc electro-galvanized provides good rust and corrosion resistance.
