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 strong, secure bonds. 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; used for crest areas of roofs to secure panels firmly.

• Sandwich Panel Fasteners: Designed for insulated panel installations; equipped with EPDM seals and aluminium bonded washers.

Crest Fixing Fasteners • Heavy Section Fasteners: Built 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 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 Heavy Section Fasteners 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 suitable for domes, green roofs, and daylighting panels.

Saddle Washers for Roofing Applications

Saddle Washers ensure uniform pressure and watertight protection under screw heads, reducing the risk of surface damage. Made with corrosion-resistant materials, they complement self-drilling screws perfectly and ensure better waterproofing for roofing installations.
