⚡ At a Glance
- • Fastening Performance: Strong penetration and reliable holding across metal, wood and plastic
- • Best for: Roofers, builders and DIYers needing quick, secure metal fixings

Supplied as a set of 52 with a matching hexagon socket for convenience. External hex head gives a large contact area for even pressure during installation.
Resists corrosion and stays strong – thanks to 410 stainless steel
410 stainless steel combines anti-rust surface treatment with higher hardness and good tensile strength. The material choice reduces corrosion in exposed or damp environments.
Longer service life on outdoor and roofing jobs, reducing the need for early replacement. Suitable for use where weather resistance matters.
Quick, one-step fastening – with self-drilling tail and optimised cutting angle
A specialised drill tail and a cutting-angle geometry allow direct entry into metal without pre-drilling in many cases. A guide groove prevents slipping and helps maintain a vertical entry.
Faster installations on thin metal panels and corrugated roofing, saving time on-site. Single-handed screw driving becomes more reliable, particularly when working at height.
Secure grip across materials – thanks to deep thread and external hexagon head
Deep thread design increases contact area within the substrate, while the external hex head and anti-slip texture improve torque transfer and positioning accuracy. Compatible with power drills, impact drivers and manual wrenches.
Firm clamping for sheet metal, PVC roofing and light timber, reducing loosening under vibration. Hex head allows easier handling with gloves and higher applied torque when needed.
