Zenith large head decking screws in T25 12G x 50mm are made for wide-board decking, using a broad head to keep boards held down as timber shifts with moisture.
The 12-gauge build adds strength to resist the cupping and bowing forces wide boards experience as timber ages, and the large head improves hold-down across the board. The T25 Star drive grips securely for high-torque driving, while the Type 17 tip helps the screw start cleanly in timber. SS304 stainless steel provides strong corrosion resistance for outdoor decks.
