British Gypsum Drywall Screws 50mm are phosphate-coated for corrosion resistance and have self-tapping points to help reliable and secure fixing of plasterboard linings to metal or timber frames. Plasterboard linings must be fixed securely to achieve optimum fire and acoustic performance. These drywall screws allow the fixing of boards up to 40mm to maximum 0.8mm gauge metal and up to 25mm to timber.
