Product overview
Drill capacity is as important as screw size
Self-drilling screws combine drilling and fastening in one operation. Diameter and length alone are insufficient: the drill point must suit the substrate type, total steel thickness and installation conditions.
For roofing or exposed work, confirm the sealing washer, coating system and corrosion environment. Installation speed and driver setting may also be included in the RFQ.
What to include in your RFQ
- DIN 7504-K basis or approved drawing
- Diameter, length and drill-point type
- Total material stack and steel thickness
- Body material, hardness and corrosion protection
- Washer option, quantity, packing and destination
