ProFix 300-Piece Self-Tapping Screw Assortment, 3.5 × 13 to 4.8 × 38 mm

What it is for

Self-tapping and self-drilling screws are the ones that save a step — one cuts its own thread in thin sheet, the other drills its own pilot hole — and the difference between them matters: using a self-tapping screw where a self-drilling one is specified means drilling first, which is the step you were trying to avoid.

The self-drilling screws here carry a No. 2 point for sheet up to 3 mm and are zinc plated. Check the point type and the sheet thickness against the job before ordering; the range of every assortment is printed on the case, and the compartments are sized so the screws do not cross over in transit.

Specification detail

300 Self-Tapping Screw Assortment covering 3.5 × 13 to 4.8 × 38 mm, zinc plated, pan and countersunk heads with a cross-head drive. Self-drilling sizes carry a No. 2 drill point for sheet up to 3 mm; supplied in a lidded case with the sizes printed in the moulding.

• Self-drilling point drills its own pilot hole, so there is no separate drilling step
• Point type stated per variant, because tapping and drilling are not interchangeable
• zinc plated with a bonded sealing washer on the larger sizes
• Length and diameter printed on the case, so the right box is grabbed first time
