Surface-treated – suitable for outdoor use
The surface-treated screw has a corrosion resistance class of C4. This means it can withstand high stress and has a rust-protective coating, making it suitable for both indoor and outdoor use.
 
Countersunk head with Torx drive
The screws come with pre-drilled cutting grooves, T20 Torx drives, and countersunk heads. The countersunk head allows the screw to sit flush with the material—perfect for when you want a less visible fastening. A bit is included.
