Coarse black collated drywall screws are the go-to choice for any drylining or boarding job that demands speed. Loaded into an auto-feed screwdriver, these screws let you work through sheet after sheet without stopping to pick up individual fasteners. If you’ve ever done a full-day boarding job the slow way, you’ll know exactly why collated screws exist.
The coarse thread is designed specifically for fixing plasterboard to timber studwork. It bites quickly and pulls the board tight without tearing the paper face. The black phosphate coating provides a degree of corrosion resistance, which matters in areas where moisture can get into the build before the finishing work is complete.
Where Coarse Black Collated Drywall Screws Fit Into the Job
These screws are sized at 3.5mm diameter across the full range, with lengths running from 25mm right up to 75mm. The shorter lengths, 25mm to 38mm, are ideal for single-layer boarding onto timber. The mid-range lengths handle thicker boards or double-layer systems. The 4.2 x 65mm and 4.2 x 75mm options step up in diameter too, giving you more pull-through resistance when fixing into engineered timber or heavier substrates.
The collated strip format is compatible with standard auto-feed screwdriver attachments that fit most cordless drill-drivers and dedicated drywall screwdrivers. The consistency of the strip means the feed mechanism works reliably without jams, keeping your rhythm on site.
Trade Pack Sizes
Available in 500 or 1000 count packs, with bulk discounts available for larger orders. If you’re pricing up a significant boarding contract or need regular stock for a busy plastering setup, get in touch for the best pricing. We can usually make it worth your while.
Pro Tip: Always match the screw length to your board thickness plus at least 25mm of embedment into the timber stud, as anything shallower risks the board working loose under normal movement.
