AnchorMark fencing and decking screw uses Delta® Seal coating to provide corrosion-resistant fastening for timber-to-steel applications. SIT® drive (TX compatible), high-efficiency thread and anti-friction coating reduce drive-in torque for faster installation.

 Aggressive self-drilling tip with wings cuts a clearance hole and will screw into steel substructures (1.25–3.0 mm) so pre-drilling is not normally required. Smooth small head sits flush for a clean finish; avoid use near pools, salt water or aggressive chemical exposure.
