Self Drilling Screws

When you’re up on the roof or tackling structural fixings, you need screws that won’t be the weak link. Our range of roofing & construction screws is built for the trade: rugged, weather-ready and reliable for timber, steel, metal sheet and heavy-duty frameworks.

Roofing screws differ from standard fixings because they’re designed to deal with exposure to the elements, movement, substrate variation and long-term durability. They often feature seal-washers, corrosion-resistant coatings or self-drilling tips so they bite into metal, wood or composite frames without fuss.

Whether you’re fixing corrugated sheets, mounting purlins, securing decking or installing rooftop ventilation, you’ll find screws built for the job-site. Our range includes screws with hex heads for easy power-driving, washered heads for weather sealing, self-tapping or self-drilling variants and finishes compatible with outdoor use, coastal zones and heavy-use construction.

Time matters on site, using the right screw means fewer callbacks, fewer leaks and no compromise. From bulk trade packs to specialist lengths and finishes, stock the screws that keep your structures locked down and standing strong through wind, rain and years of use.

FAQs 

1. What exactly makes a screw suitable for roofing and construction use?
   

   Roofing & construction screws are made with features like self-drilling tips, weather-proof coatings, seal-washers and drives suited for power tools. They’re designed to withstand external conditions and structural loads better than standard interior screws.

2. Can I use these screws on both metal and timber substrates?
   

   Yes, but you must choose the correct variant. Some are designed specifically for metal-to-metal (self-drilling into steel), while others are for timber or wood-based substrates. Match the screw to your substrate for best results.

3. What finish or coating should I pick for outdoor or exposed roofs?
   

   Outdoor use demands corrosion-resistance: look for screws with zinc plating, galvanised finish, stainless steel or special coatings. Also, ensure the head/washer system provides a weather-tight seal.

4. Do I need to pre-drill holes before using roofing screws?
   

   Many roofing screws come with self-drilling or self-tapping tips so pre-drilling is often unnecessary, especially for metal-to-metal fixings. However, in very thick or high-hardness substrates, a pilot hole may still help.

5. How long will a properly installed roofing screw last?
   

   If the screw is correctly specified for substrate, environment and finish, then installed with correct technique (including proper washer seal and drive depth), it should last many years, resisting corrosion, movement and exposure, keeping your roof and construction secure for the long haul.
