Self-cutting screws drill their own tapping hole to close tolerances and form their mating thread themselves. The specially formed and stamped drill point prevents any drifting around the surface of the component and allows rapid sport drilling. There is no longer any need to centre punch the drilling point.
Stamped drill points: safe and secure drilling without the need for prior center punching. |
Self-cutting screws: fasten quickly and cheaply without the need of a pilot hole. |
Advantages:
- Fast and cheap handling
- Savings of up to 50% are possible compared with conventional tapping screws
