Metal Construction Timber to Light Section Screws – Countersunk – Wing-Tip – Self-Drilling – Exterior – Silver Organic

Specifically designed to attach wood to metal (Max. 4mm). Coarse self-tapping thread with wings designed to ream out the timber, so the screw can achieve Max. R.P.M. without burning out. When the wings hit the metal they will break off to permit the thread to self-tap into the metal.

• Exterior plating gives a reliable and durable corrosion resistant coating which resists 500 hours salt-spray
