Drive Screw – Galvanised

The galvanised drive screw is the standard fixing choice when attaching roofing and cladding sheets to timber purlins. Whether you are working on agricultural buildings, industrial units, or any steel sheet roofing application over a timber substructure, this is the screw that gets the job done without fuss. The galvanised drive screw conforms to Eurocode 5 and service class 2, which means it meets the structural and environmental requirements expected of roofing fixings used in exposed and semi-exposed conditions.

Galvanising gives these screws medium duty rust protection, making them appropriate for most standard outdoor applications where the fixings are not in constant contact with standing water or particularly aggressive environments. They are not stainless, so they are not the right choice for coastal installations or heavily corrosive settings, but for the vast majority of farm buildings, warehouses, and commercial roofing jobs across the UK, they do exactly what is required.

The drive screw design means these are installed with a power driver rather than a traditional screwdriver action. They drive quickly through sheet material and bite firmly into timber, which speeds up installation considerably on large roofing runs. When you have a full roof to fix and daylight is not unlimited, a fastener that goes in clean and holds tight without pre-drilling matters more than people often realise.

Galvanised Drive Screw Sizes and Pack Options

These screws are available in a range of lengths and shank diameters to suit different sheet thicknesses and purlin depths. Sizes run from 50 x 5.40mm up to 150 x 6.40mm, covering light to heavier gauge sheet applications. Pack weights include 0.5kg, 1kg, 2.5kg, and 25kg options, available in cartons, TIMbags, and TIMtubs. Buying in bulk on a larger job makes obvious sense, and the 25kg carton option is there for exactly that reason.

Knowing how many fixings you need before you order is worth taking a moment over. Sheet manufacturers typically specify a fixing pattern, and it is worth following their recommendations rather than guessing. Running short of screws midway through a roof fix is a particular kind of frustration that nobody needs.
