This is the collated version of TIMCO’s self-drilling plasterboard screw, loaded on strips for a collated gun. The self-drilling point goes straight into metal wall and ceiling track up to 2mm without spinning or pre-drilling, which is more than a standard fine thread will handle. The bugle head pulls the board tight and sinks below the paper, ready to tape or skim. Running them off a gun keeps you upright and quick on a big drylining job.
