Overview
Zenith Large Head Decking Screw t25 12g x 50mm ss304 50 Pack is designed for wide board decking applications, providing strength and stability for timber projects.
The Zenith Large Head Stainless Steel Decking Screws are specifically engineered for wide board decking, particularly suitable for 140mm boards that are prone to movement due to moisture changes. With a 12-gauge construction, these screws offer increased strength to resist cupping and bowing forces from ageing timbers. The large head design ensures optimal hold-down capabilities, enhancing the durability of your decking. The T25 Star drive recess facilitates one-handed installation while minimising cam-out, and a star drive bit is included for convenience. For best results, it is recommended to pre-drill a 4mm or 5/32" hole and pre-countersink before securing.
