MACSIM's zinc plated long thread timber screws deliver reliable fastening performance for timber-to-timber applications with superior grip and holding power. The extended thread pattern runs nearly the full length of the screw, maximizing contact with the timber for stronger joints and reduced splitting. The zinc plating provides effective corrosion resistance for interior and light-duty exterior applications.
Each 8G x 20mm screw features a countersunk head that sits flush when driven, creating a clean finish on timber surfaces. The Phillips drive accepts standard No.2 driver bits for efficient installation, while the long thread design ensures maximum pull-through resistance in softwoods and hardwoods. Ideal for cabinetry, furniture assembly, framing, joinery, and general carpentry where strong timber connections are essential.
