Timco Metal to Timber Screws 5.5x120mm, Countersunk, Self-Drilling, 100pcs
Timco's self-drilling metal-to-timber screws (5.5x120mm) feature wing-tip design & A2-304 stainless steel for exterior use.
The Timco Metal to Timber Screws are specifically engineered for attaching wood to metal sections up to 12mm thick. Featuring a Wing-Tip design, these screws achieve maximum RPM without burning out by reaming the timber as they drill. Once the wings hit the metal, they break off, allowing the screw to self-tap into the metal efficiently.
Constructed from hardened carbon steel drill tips fused to A2-304 Austenitic Stainless Steel bodies, these screws offer excellent corrosion resistance and durability. The partially threaded design ensures strong holding power while reducing splitting in timber.
