Timber-Tite 6.5 x 145mm Heavy Duty Timber & Landscape Screws Box of 20

Stronger Than a Bolt, Neater Than a Lag Screw

For decades, building heavy timber structures like retaining walls, large deck frames, or pergolas meant drilling wide holes and using bulky High Tensile (HT) bolts or ugly hex-head lag screws. Timber-Tite changes the game entirely. These screws are independently proven to offer greater shear and tensile strength than a standard HT bolt. Even better, they feature a precision countersunk head. Instead of leaving a chunk of metal sticking out of your wood, the Timber-Tite screw pulls itself completely flush. This allows you to easily fix flat fascia boards, decking planks, or decorative cladding directly over the joints without any interference.

Advanced Net-Coat® Green Protection

If you are building outdoors, you are likely using pressure-treated timber. The chemicals used to prevent rot in treated wood (especially modern copper-based treatments) are highly corrosive and will rapidly eat away at standard zinc or galvanized screws, causing the structure to eventually fail. The Timber-Tite range is armed with a proprietary Net-Coat® Green finish. This specialized barrier specifically neutralizes those corrosive effects, ensuring your fasteners maintain their structural integrity through years of harsh weather and damp conditions.

Fast, Effortless Driving

Time is money on a landscaping job, and having to pre-drill pilot holes for every heavy-duty fixing is incredibly tedious. Timber-Tite screws are designed to be driven straight into the wood. The sharp point and aggressive thread pattern catch instantly, drawing the massive 145mm shank deep into the timber without splitting the grain. Combined with the high-torque grip of the Torx T30 drive, you can sink these massive fasteners using a standard impact driver in a fraction of the time it would take to install a traditional bolt and nut.

Key Features

• Net-Coat® Green Protection: A specialized coating that fiercely resists the corrosive effects of ACQ and other modern pressure-treated timber chemicals.
• No Pilot Hole Required: The advanced thread and point geometry eliminates the need for pre-drilling in the vast majority of softwoods and landscaping timbers.
• Anti-Split Technology: Engineered to slice through the wood fibers cleanly, preventing the timber from splitting or bulging even when driving close to the edge.
• Torx T30 Drive: The deep six-lobe Torx recess ensures maximum torque transfer from your drill without the bit slipping (cam-out) or stripping the head.
• Indoor & Outdoor Versatility: While perfect for outdoor landscaping, their neat finish and high strength make them equally suited for heavy indoor structural carpentry.
