Product Features
- DRILLS ITS OWN HOLE - the drill point cuts through steel and taps machine threads in one motion; no pilot hole, no punch, no layout time
- TRUE DRILL POINT GEOMETRY - fluted #3 point evacuates chips as it cuts, preventing the point-melt that makes cheap self-drillers wander and squeal
- HEX WASHER HEAD - positive drive with a magnetic hex setter, no cam-out under impact driver torque; integral washer face spreads the clamp load
- ZINC PLATED CASE-HARDENED STEEL - drills mild steel, purlins, studs and angle day after day; the standard metal framing self-driller
