ESSVE Concrete screw with hex head and flange designed for quick and easy fixing in concrete.

Specially hardened screw that is can be screwed directly into a drilled hole without a plug. It has a “hi-lo” thread which facilitates installation. The screw is produced in hardened steel with bright zinc plated surface treatment. It has a hex head.

An impact screwdriver or impact wrench is recommended for installation. See the installation instructions at the end of this section. NOTE! The concrete screw does not require a pre-tensioning torque to ensure fixing. The final tightening torque applied must not be greater than required to hold what is fixed in place. Tightening torques specified in the table must not be exceeded.
