FirmGrip twin thread wood screws are high-performance fixings designed for fast insertion and strong holding power in timber and sheet materials. Manufactured from hardened steel and finished with bright zinc plating, these screws provide durability and resistance to corrosion for general construction and joinery use. The twin-thread design allows rapid driving with reduced splitting, making them ideal for both trade and DIY applications.
