Description
Overview:
The Timco Hex Self-Drilling Screw 5.5 x 70 mm is a steel fastener designed for quick, secure fixing into light section steel without pre-drilling. The hexagon head allows positive drive using a nut setter or socket, making it a reliable choice for roofing and cladding work where consistent torque and tightness matter. With a self-drilling tip, it both drills and taps its own thread in a single operation, saving time on site and reducing tool changes. Suitable for sheet-to-steel and accessory fixings in construction, fabrication, and maintenance tasks, it is commonly used by roofers, builders, and installers working on metal frames and panels. Supplied in a pack of 100 for efficient stocking and consistent results across larger jobs.
Key Features:
- 5.5 mm diameter x 70 mm length for reliable engagement in light section steel
- Self-drilling tip eliminates the need for pilot holes in suitable materials
- Designed for steel thicknesses up to 5 mm to achieve a secure hold
- Hexagon head for strong drive and easy installation with nut setters or sockets
- Consistent thread form for clean cutting and controlled pull-up on metal sheets
- Speeds up installation by drilling, tapping, and fastening in one operation
- Suitable for fixing roofing panels, cladding, and metal accessories to steel purlins
- Supplied as a pack of 100 to cover both small repairs and larger projects
Typical Applications:
Securing metal roofing sheets and cladding to light steel purlins, fixing sheet-metal trims and flashings, assembling metal frames and channels, installing ventilation and cable management supports to steel structures, and general construction or maintenance tasks involving sheet-to-steel fixings in workshops, warehouses, farm buildings, garages, and garden buildings.
