CONCRETE BOLTS are a modern alternative to metal anchors. With a hex head for standard tools, they are manufactured from high grade steel to QS9000 standards and specially heat treaded to achieve a tensile strength of 800n/mm2. The interlocking high low thread pattern self-taps into the substrate and gives very high pull out values, whilst the serrations on the threads removes more debris and reduces fixing stress, this also allows for closer fixing centres than expansion anchors and can be used closer to the edge of substrates. The cutting ribs on the tip aid insertion and the high quality Yellow Tropicalised coating prevents corrosion giving a safe reliable anchor which can be removed and re-fitted in the same hole if necessary. CONCRETE BOLTS are available in a wide range to suit common fixing applications.
