Buildex 12G x 68mm Class 3 galvanised SuperTEKS screws are self-drilling metal fixing screws with a TEKS point, supplied in a 250 pack for securing metal components into steel. The TEKS self-drilling tip penetrates thick steel effortlessly and drills its own hole, removing the need for pre-drilling.
At 68mm long, these SuperTEKS screws reach through thicker assemblies into steel, while the Class 3 galvanised finish provides long-term corrosion protection for general external and sheltered applications. The hex head allows high-torque driving with a nut driver and the screws come with a seal. The 250 pack is a practical mid-volume option for builders and tradespeople working with metal.
