Applications: For attaching ModWood Xtreme Guard Decking to steel and aluminum substructures, including starter boards, end boards, steps, screening and fascia applications. These fasteners are to be used in conjunction with ModWood hidden fixing systems.
Triple Strength Corrosion Resistance: 410 stainless steel, zinc plated and epoxy coated.
Mechanical Features: #3 drill point designed for use with up to 25mm thick decking attached to steel and aluminum substructures up to 4mm thick, including steel gauges 18-12 (as well as two 14g joists doubled up). Wings increase the speed and effectiveness of the drill point, and prevent mushrooming.
Usage Notes: Follow all instructions provided with ModWood Xtreme Guard Decking. Ensure screw head is always flush with deck board surface. Handy Tip – use the ModWood Deck Screw Depth Setter which makes this easy! You MUST pre-drill ModWood Xtreme Guard decking prior to installing fastener! Use a 4.8mm drill bit. To ensure full holding power, wings must shear off cleanly and three full threads must be visible beyond the metal structure.
Corrosion Information: All metal fasteners have the potential to corrode. Fasteners used in corrosive environments and materials require higher levels of corrosion resistance. These screws are made of grade 410 stainless steel and an epoxy based polymer resin coating over zinc plate. For applications exposed to salt water air, near large bodies of salt water, swimming pools or other areas where corrosion is more likely to occur, always use grade 316 stainless steel.
