Ingenious sleeve geometry combined with highest tension resistances due to prestressing steel material properties provides an increased undercut percentage, which leads to crack retraction effect. Due to its balanced design, this behavior applies up to C80/95.
Best shear resistance with no compromise on ductility, thanks to the bolt‘s premium material and cold forming technology.
An optimized coating throughout the anchor reduces expansion forces, which allows for minimum spacing, edge distances and member thicknesses.
If it can't be designed with Hilti HST3, it can't be designed with an expansion anchor!
HST3 delivers the highest resistance for all applications including seismic. HST3 provides the added benefit of a “crack retraction effect“ and delivers perfect load displacement under static and seismic loading.
HST3 delivers the highest versatility in the jobsite: HST3 is the only metal expansion anchor ETA approved to be installed with standard hammer drill bits, with diamond core bits and with Hollow drill bits without load drop.
HST3 meets challenging design requirements such as smallest edge and spacing distances in combination with highest resistance values.
