Concrete screws have unique design and excellent performance to anchor and fix the objects temporarily or permanently in the concrete base material. Heavy duty concrete screws are designed hardening body by heat treatment and heavy duty high and low double self tapping external threads to drill into the concrete structure substrate easily and quickly,being suitable to install and use medium and heavy loads.

    Concrete screw anchor bolts can replace some of concrete expansion bolts and fasteners and can be easily removed no damage the base materials after installing. Easydrive concrete screws are installed by high speed self tapping rotation under driving with the impact wrench,not swell and burst around the base,being very suitable to install near the substrate edge or close to other anchors or fixings. 

    Being widely used in the concrete,masonry or brick works to anchor and fixing the objects, providing metric and inch sizes with various head are suitable for different installation and use places. Besides ZP or ZYP, hot dip galvanized or Dacromet spraying are available with good oxidation resistance, rust resistance and chemical corrosion resistance.
