VDE High Leverage Combination Pliers 200mm

These Forgefix Tec Fix Roofing Screws are self drilling, winged and have countersunk heads.

APPLICATION:
Suitable for use when fixing timber to heavy section steel, thickness from 6.0mm to 12.5mm.

Self-drilling screws have a drill-shaped point to cut through the substrate to eliminate the need for drilling a pilot hole. They are designed for use in soft steel or other metals.

The Phillips screw has four simple tapered slots. It is designed so that a Phillips tip screwdriver can turn a Phillips screw with increasing torque. When the torque gets to be too strong for the tip then the screwdriver tip winds itself out of the screw thus preventing over-tightening and or damage to the screw head. The countersunk heads are designed to sink flush with substrates to leave a smooth surface finish.
