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.

Size: 12G x 50mm
Pack quantity: 50
Head type: T25 Star head
Point type: Type 17 tip
Material: SS304 stainless steel
Finish: Stainless Steel 304
Colour: Silver

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.

Worth every cent

Did a lot of comparison shopping before buying here and I have no regrets. Best price I found anywhere and delivery was fast — 3 days to Melbourne. Product feels genuinely premium, not cheap at all. Packaging was solid too, box arrived in perfect shape. Will be back for more.

Perfect gift — loved it

Bought this as a replacement for one I have had for years and I am glad I upgraded. The new one is noticeably better. Had a tracking number within a few hours of ordering. Packaging was excellent, nothing damaged. Already told a few mates about this site. Great prices and genuinely fast shipping.
