Self-Tapping Screw – Countersunk – Zinc
Zinc plated countersunk self-tapping screws for tidy, flush metal fixing in internal trade applications.
About Zinc Countersunk Self-Tapping Screws
Zinc countersunk self-tapping screws are designed for metal-to-metal fixing where a clean, low-profile finish is required. Once installed, the countersunk head sits neatly level with the surface, making them suitable for visible fixings or where components need to sit flat.
These screws are intended for use with a pre-drilled pilot hole, allowing controlled thread formation in metal. This helps improve installation accuracy and reduces stress on both the fixing and the material.
The zinc plated finish provides corrosion resistance suitable for dry, internal environments, making these screws a practical choice for everyday site and workshop use.
Typical Applications
Zinc countersunk self-tapping screws are commonly used in:
- Sheet metal panels and covers
- Brackets, plates and light steel components
- Electrical enclosures and containment
- General fabrication and maintenance work
They’re well suited to applications where appearance, fit and consistency matter.
