Key Features

🪵 Timber to Metal Fixing – Purpose-built to securely attach wood to heavy section steel in construction and fabrication projects
🌀 Wing-Tip Innovation – Wings ream timber smoothly for fast drive, then snap on contact with steel to allow self-tapping threads to bite cleanly
🔩 Countersunk Head – Creates a flush finish that improves safety and appearance in finished work
⚙️ Partially Threaded Design – Maximises clamping force and ensures stronger timber-to-steel connections
🛡️ Zinc Plating Protection – Provides durable resistance against rust and wear for reliable indoor and exterior use

Product Description

These Metal Construction Timber to Heavy Section Screws are engineered to fasten wood to steel quickly and reliably. The wing-tip design clears timber during drive-in, breaking off when contacting steel so the self-drilling thread can cut smoothly into metal. Their countersunk head offers a flush, professional finish while the partially threaded design increases clamping force for a stronger hold. Zinc plating protects against corrosion and ensures long-lasting durability across a range of environments. Ideal for builders, contractors, and fabricators, these screws deliver dependable performance in demanding timber-to-steel applications.
