OC-ZF Self-drilling screws
The special drill bit shape designed to provide quick and trouble-free installation in metal constructions made from cold formed sections
Features and benefits

- The drill bit is designed to provide quick and trouble-free installation in the steel. Sharp point of the drill prevents movement of the surface of the fixture.
- Corrosion-resistant protection (500h in Neutral Salt Spray test)
