INDU-PROG CONCRETE SCREW TX DRIVE/BITS
Area of usage
ESSVE Concrete screw designed for quick and easy fixing in concrete, brick, hollow block and hollow brick.
Specially hardened screw that is can be screwed directly into a drilled hole without a plug. It is fully threaded with a
“hi-lo” thread which facilitates installation. The screw is produced in hardened carbon steel with bright zinc plated
or CorrSeal surface treatment. Generally, the loading capacity is improved by increasing the fixing depth. For
fixing in materials other than concrete a pull-out test should be made according to the evaluation method
approved by Boverket, (The Swedish National Board of Housing, Building and Planning) to produce an applicable practical load bearing capacity. The concrete screw is also tested and approved
for pulsating loads.
An impact screwdriver is recommended for installation. See mounting instructions below. NOTE! The concrete screw does not
require a pre-tensioning torque to ensure fixing. The 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.
