✅ Variety of Finishes – Choose between black/grey phosphate and zinc-plated screws to suit different environmental conditions.
✅ Fire Rated – Many drywall screws, such as those available at Next Day Fixings, are A1 fire-rated, making them safe for use in various building projects.
Cons:
❌ Not Universal – Drywall screws are specifically designed for plasterboard and stud work; using them for other materials may result in suboptimal performance.
❌ Corrosion Sensitivity – Standard drywall screws may not be suitable for high-humidity environments unless they have a protective coating like zinc plating.
❌ Brittle in Certain Applications – The hardened steel construction makes drywall screws more brittle than traditional wood screws, so they should not be over tightened.
