Timco Bi-Metal Timber to Steel Screws, 5.5x65mm, 200pk
200 Timco bi-metal screws for wood-to-steel fixing (5.5x65mm). Self-drilling, corrosion-resistant with wing-tip design.
The Timco Bi-Metal Timber to Light Section Screws offer a professional solution for attaching wood to light section steel (maximum 5mm thickness). These screws feature a unique wing-tip design that reams out the timber as it drills, allowing maximum RPM without overheating. When the wings encounter metal, they break away to enable the screw's self-tapping thread to securely fasten into the steel.
Constructed from A2-304 Austenitic Stainless Steel with a hardened carbon steel drill tip, these screws combine corrosion resistance with exceptional drilling performance. The countersunk head with ribs provides a flush finish while preventing over-tightening, making them ideal for exterior applications where both strength and appearance matter.
Ready for demanding applications, these screws feature:
- Self-drilling No.3 point for easy installation
- Phillips recess for secure driving
- Bi-metal construction for durability
- Organic silver coating for enhanced protection
With an effective thread length of 41mm, they're perfect for timber thicknesses between 29-43mm. Supplied in packs of 200, these screws are suitable for fencing, decking, cladding and other outdoor construction projects where wood needs securing to light steel sections.
