Essve Concrete screws 6K with washer

ESSVE concrete screws are designed for quick and easy fastening in concrete, brick, hollow material, and hollow brick. It is a specially hardened screw that is screwed directly into the drilled hole without an anchor. The screw is fully threaded with a "hi-low" thread, which facilitates installation. The screw is made of hardened steel, with a zinc-coated surface or CorrSeal coating. The load capacity improves by increasing the depth of fastening. For fastening in materials other than concrete, a test load must be performed according to approved evaluations by the Construction Board to obtain suitable practical load. Concrete screws have been tested and approved for use in pulsating loads.
