Metal-Tite Self-Drilling Screws
Designed for efficient metal-to-metal connections, Metal-Tite Self-Drilling Screws integrate drilling and fastening into a single operation, saving time while ensuring tight and durable joints. These fasteners are manufactured using heat-treated carbon steel and protected with high-performance anti-rust coatings for enhanced corrosion protection. With a tested service life of over two decades under tough conditions, they are ideal for industrial roofing and metal structures.
Subtypes include:
• Needle Point Stitching Screws: Perfect for sheet-to-sheet fixing in steel structures; engineered for rust resistance.
• Crest-Fix Hex Head Screws: 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: Used for thick steel connections and decking systems, offering superior penetration for dense substrates.
Timber-Tite Wood-to-Metal Fasteners
The Timber-Tite Self-Tapping Screws are designed for secure timber-to-metal fastening without the need for pilot holes. Their aggressive cutting tips and deep threads create secure, long-lasting bonds suitable for wooden roof structures and frames. The screws feature protective finishes to maintain strength in humid conditions and are available for both valley and crest fixing:
• Valley Fixing Fasteners: Shorter screws for low points in roofing profiles to prevent leaks.
• Crest Fixing Fasteners: Longer variants for securing sheets at roof crests, providing excellent wind uplift resistance.
Frame-Tite Fasteners
The Frame-Tite range provides reliable fastening for steel wall frames and structural assemblies. Made from heat-treated steel, these screws resist bending and feature under-head nibs that ensure tight sealing. They deliver consistent torque and easy installation, making them suitable for industrial frameworks and heavy-structure assemblies requiring precision alignment.
POLYXPAND UV-Resistant Fasteners for Skylights
The POLYXPAND series from BDN Fasteners India offers dedicated fixings for translucent roofing and skylight systems. Built with sunlight-resistant polymers, these screws flex with sheet movement to prevent stress fractures. Their flexible design, eco-friendly washers, and weatherproof coating make them ideal for skylights, greenhouses, and transparent roofing systems.
Saddle Washers
Saddle Washers enhance sealing and distribute the load evenly under screw heads, reducing the risk of sheet deformation. Made with long-life composite materials, they pair seamlessly with roofing fasteners and ensure better waterproofing for roofing installations.
