Metal-Tite Series – Self-Drilling Roofing Screws
Designed for quick and strong metal joints, Metal-Tite Self-Drilling Screws integrate drilling and fastening into a single operation, saving time while ensuring strong, secure bonds. These fasteners are crafted from hardened carbon steel and coated with Ruspert or zinc for extended rust resistance. With a lifespan exceeding 20 years under tough conditions, they are ideal for galvanized roofing and steel constructions.
Subtypes include:
• Stitching Fasteners (Needle Point): Suitable for fixing steel sheets to steel substrates; coated for corrosion protection.
• Crest Fixing Fasteners: Offered in a range of lengths for crest-mounted applications; ideal for securing roofing panels along ridge lines.
• Insulated Panel Fixing Screws: Engineered for composite sandwich panels; feature watertight sealing components for leak-free installation.
• Heavy-Gauge Metal Fasteners: Built Sandwich Panel Fasteners for heavy-duty applications like steel decking, capable of drilling up to 12.8 mm thick steel.
Timber-Tite Self-Tapping Screws
The Timber-Tite Self-Tapping Screws are engineered for wood-to-metal applications without the need for pre-drilling. Their sharp points and coarse threads create tight, durable joints suitable for timber roofing, sheds, and Timber-Tite Self-Tapping Screw framing. The screws feature rust-resistant coatings to maintain strength in humid conditions and are available for both valley and crest fixing:
• Valley Fixing Fasteners: Compact variants for fixing through roof valleys, ensuring watertightness.
• High-Point Fix Screws: Extended-length screws offering superior resistance to wind forces at crests.
Frame-Tite Structural Screws
The Frame-Tite range provides high-performance connections for framing and load-bearing systems. Made from reinforced carbon steel, these screws offer high tensile strength and a precision seal beneath the head. They deliver consistent torque and easy installation, making them suitable for industrial frameworks and heavy-structure assemblies requiring precision alignment.
