MTHG Cement Sheet / Underlay Screw (Collated)

Product Tabs

Product Details

The MTHG underlay screw is designed for fast and secure underlayment to subfloor and wall installations.

Unlike nails, the MTHG has an intricate thread pattern designed to prevent squeaking by holding underlayment tight to the subfloor and thus preventing pull-out.

Its compact trim-head allows for a flush surface and prevents floor coverings from settling in countersink recesses.

Replacement Bit

These coated fasteners possess a level of corrosion resistance that makes them suitable for use in some exterior and corrosive environments and with some preservative-treated timber.
For applications in higher-exposure applications, consider Type-300 series stainless-steel fasteners for superior corrosion resistance. Bit(s) included with every box of screws.
Pre-drilling and countersink may be necessary at ends, butt joints, and on applications where denser material is used. Follow board manufacturers recommendations where applicable.
