Simpson MTH Underlayment Screw

When installing subfloor, you need a screw that will tighten the underlayment to the subfloor without pulling out or sticking up. The MTH underlayment screws from FMW Fasteners will do just that.

Use the underlayment screw to attach the underlayment to the subfloor. The thread pattern on the shaft will secure the layers together and prevent annoying squeaking sounds. The trim head will sink into the material for a flush finish. With no bumps, the flooring will have a smooth surface.
