Believing in the great advantages that a concrete screw can offer compared to a torque controlled expansion anchor – in terms of time saving, ease of installation, edge distance and spacing – Tecfi SpA has continued to invest in its concrete screw range, which now includes the HXE-CONCRETO®, and three new A4 stainless steel concrete screws.
The HXE-CONCRETO® is C2 and C1 certified on diameters 16mm and 12mm, and while diameter 10mm reached the category C1, it is also ETA-CE certified in Option 1 for cracked and non-cracked concrete and classified R120 for fire resistance (from diameter 8mm to 16mm).
The HXE range is very wide, including a hexagonal flanged washer head screw (HXE01), a flat countersunk with six spline recess head screw (HXE03) and a double thread screw with nut and washer (HXE02), which is also available with a large washer (HXE12).
Tecfi has also launched a line of A4 (AISI 316) stainless steel concrete screws – available with a hexagonal flanged washer head in diameters 6mm, 8mm and 10mm. The company is also planning to launch three new A4 stainless steel concrete screws – a flat countersunk with a six spline recess head screw (HX73), a pan with a six spline recess head screw (HX75) and a pan washer with a six spline recess head screw (HX76).
Tecfi also offers a line of concrete screws with special finishing under the Steel Saver® brand. This includes the HX41 screw with hexagonal flanged washer head with 1,000 hours in salt spray test; the HXB02 double thread screw with nut and washer and the HXS01 screw with a flat countersunk six spline recess head – both with 500 hours salt spray test. Finally the HXT01 screw with mushroom six spline recess head – with 500 hours salt spray test is also available.
To further demonstrate this investment into concrete screws, Tecfi states that it was the first company to achieve the C2 and C1 Performance Category for the installation of its concrete screws in high seismic hazard zones in April 2015.
