Timco Metal Timber to Heavy Steel Screws, 5.5x45mm, Zinc, 200pcs

Timco Metal Construction Timber to Heavy Section Screws are designed for fastening wood to heavy section steel (up to 12mm thick). These screws feature a metric thread with winged tips, ensuring efficient wood reaming while preventing burn-out at high RPM. The wings break off upon encountering steel, allowing the self-drilling tip to tap securely into metal. Ideal for heavy-duty construction and woodworking applications.

Key Features:

• Self-drilling design eliminates the need for pre-drilling, saving time and effort.
• Ribbed countersunk head provides a flush and secure fit.
• Zinc finish enhances corrosion resistance for lasting durability.
• Case-hardened carbon steel ensures superior strength and resistance to snap-off.

Efficient Installation:

The wing-tip design maximises drilling efficiency in wood, reducing friction and heat build-up. When the screw reaches steel (≤12mm thick), the wings shear off, enabling the thread to cut smoothly into the metal. Phillips recess ensures compatibility with standard screwdrivers, making installation quick and hassle-free.

Versatile Use:

Perfect for decks, timber frames, fencing, and structural joints where wood meets heavy steel. The effective thread length (15mm) ensures strong clamping force.
