Application

For plywood, chipboard and OSB to wood installations, such as flooring.

Description

The MTH underlayment screw is designed for fast and secure underlayment to subfloor installations. Unlike nails, the MTH underlayment screw has an intricate high-low thread pattern designed to prevent squeaking by holding plywood tight to the subfloor and thus preventing withdrawal. Its countersunk compact trim-head allows for a flush surface finish and prevents floor coverings from settling in countersink recesses.


Features and benefits:

  • Steel with grey phosphate coating or yellow zinc coating.
  • 25 mm and 32 mm lengths CE marked to EN 14592.
  • Deep recessed square drive holds bits tight, reducing cam-outs.
  • High-low thread for easy driving and holding underlayment tight.
  • Specially-designed sharp point for fast starts.
  • Trim-head with nibs for easy countersinking.
  • Plywood or OSB to wood applications.
  • Recommended for installing Fermacell board to steel up to 0.9 mm thickness.
  • Bit (BIT2SE) included in every box for 25 mm and 32 mm screws.
  • Bit (BITL2SE) included in every box for 19 mm screws.
