Heifix Decking Screws Pozi Countersunk - FREE Screw Bit Included (QTY 200, 4.5 x 65mm)

FREE 25MM PZ2 BIT INCLUDED - Each pack includes a matching 25mm PZ2 bit so you can start your project immediately. COARSE SINGLE THREAD FOR DECKING - A heavy duty coarse thread provides strong grip and increased holding power in softwood and hardwood decking boards, helping each screw pull down tightly for a secure fit. ENGINEERED FOR EXTERIOR TIMBER - Ideal for decking, fencing and general outdoor timber work. The green heavy duty weather resistant coating delivers excellent corrosion resistance in wet or humid conditions. ACCOMMODATES WOOD MOVEMENT - Designed to work with the natural expansion and contraction of timber which reduces splitting and maintains long term stability. COUNTERSUNK HEAD - Creates a clean, flush finish in the timber. The strengthened head design improves durability and helps reduce snapping during installation. PZ COMPATIBLE DRIVE - The pozidrive head allows improved torque transfer with a lower risk of cam out which keeps your bit engaged securely. MILLING RIBS UNDER THE HEAD - The ribs bite into the timber as the screw seats which prevents unwanted movement and improves stability where vibration is present.
