Details

The Siniat GTEC Self Drilling Screws 3.50x42mm are engineered specifically for professionals installing plasterboard onto thick gauge metal studs. Designed to deliver consistent performance on demanding jobs, these screws offer durable, corrosion-resistant fixing that tradespeople can rely on for structural integrity and speed on site. Please note screws are supplied in boxes of 1000.

Application

These self drilling screws are tailored for attaching a variety of GTEC plasterboard products to metal studs thicker than 0.7mm. They excel in drywall installation where a secure hold is critical, preventing movement or loosening over time. Trades such as plasterers, contractors, and dry liners benefit from the screw’s precise drilling tip and fine thread, which reduce the risk of damaging plasterboard or metalwork during installation. Correct positioning is essential: screws should be placed at least 10mm from bound edges, 13mm from cut edges, and 3mm from the metal stud edge, with a minimum 10mm penetration into the stud to ensure a reliable fixing.
