## Questions & Answers

**Q: Are these suitable for drilling/screwing into a catnic lintel approximately 3mm/4mm thick? Will I need a pilot hole?**
A: I’m not sure I used them to drill into upvc and through aluminium frame inside I would drill a tapping hole the same diameter as the tip as you are going into steel

### ⭐⭐⭐⭐⭐ Great self drilling screws.
*by C***S on 26 February 2026*

Great item, great price.

### ⭐⭐⭐⭐ Self tapping screws
*by P***Y on 2 February 2024*

Not bad quality but good to buy more than you need as a lot of the screw heads shredded when screwing into mild steel box sections . Had to use pliers to remove the screws and try again with another screw or just hammer in to finish .
