AnchorMark S2-TTM Decking Screw 5.5 x 45mm A4/316 Pack of 100

The AnchorMark S2-TTM Decking Screw is engineered for decking and cladding with steel substructures. Made from 316 stainless steel with an additional zinc-coated steel tip, these screws offer exceptional weather resistance and durability. The self-drilling tip ensures quick and easy installation, while the small head diameter allows for a clean, flush finish. The aggressive drilling tip with wings cuts a clearance hole, eliminating the need for pre-drilling for steel thicknesses between 1.25 – 3.0 mm. The SIT® drive ensures optimal torque transmission and a snug fit, while the high-efficiency thread with anti-friction coating reduces drive-in torque.

Key Features:

• Material: 316 stainless steel with an additional zinc-coated steel tip for high weather resistance
• Self-Drilling Tip: Quick and easy installation; prevents timber tearing and splitting
