Index HP75072 – Concrete Screw Flat Head Hi-Lo Thread Diamond Point Torx-30 Dichromate 7.5 x 072

Direct fixing screw, with countersunk flat head and TX hexalobular footprint. Allows you to attach elements such as sandwich panels or door and window frames to materials such as concrete, solid brick or wood. As it is direct fixing, it does not require the use of dowels for installation. It has a special high-low 60° / 30° fluted thread and produces no expansion efforts in the concrete, which prevents possible damage to the material. It is installed by impact wrench through the element to be fixed, after making a pre-drill. Can be installed over dry, wet or flooded holes. Incorporates grooves under the head that allow direct countersinking in soft materials during drilling. It is made of stamped carbon steel and has a bricomated coating, which gives it greater resistance. It is a coating suitable for a corrosion level C2, typical of indoor with temporary condensation or outdoors in rural areas with very low pollution. INDEX A PERFECT FIXING has different sizes of this screw, among which to choose according to the specifics of the installation. It also features round PVC plugs (HP TP) to cover the head of HP concrete screws after installation, improving the finish of the joints.
