CONCA Countersunk Head Screw-Bolt by ICCONS® is a screw-in, self-tapping concrete and masonry screw anchor for use in a wide range of applications found in the residential, commercial and infrastructure construction spaces. Installation is quick and easy: simply drill, clean the hole and screw in the anchor. Available in 6mm and 8mm in various lengths, CONCA Countersunk Head Screw-Bolts by ICCONS® are the economic anchoring solution for non-safety-critical applications. CONCA Screw Bolts by ICCONS achieve high loads while generating low expansion forces, making it a great alternative to adhesive anchors. Unlike mechanical expansion anchors, the CONCA Screw-Bolt keys into the base material for the entire depth and diameter of the hole, not just at the base. The CONCA Screw Bolt is a versatile anchor, installable in a wide range of base materials such as concrete, block, brick, timber, marble, and stone. For safety-critical applications, please see ICCONS Thunderbolt PRO and Toge screw bolt ranges.
