MTH Underlayment Screw

MTH Underlayment Screw Installation
Prevents Squeaks by Holding Underlayment Tight

The MTH Underlayment screw is designed for fast and secure underlayment-to-sub floor installations. Unlike nails or staples, the MTH Underlayment screw prevents squeaking by holding underlayment tight to the sub floor by resisting pullout. Its compact trim head allows for a flush surface and prevents floor coverings from settling in countersink recesses.

Strong-Drive® WSNTL Subfloor Screw

Strong-Drive WSNTL Subfloor Installation
For Subfloor and Sheathing Applications

The ICC-ES ESR-1472 code-listed Strong-Drive WSNTL Subfloor screw has a twin-lead thread pattern that allows for quick and secure installations. With lateral, shear and withdrawal values that exceed those of 10d common nails, the holding power of the WSNTL screw eliminates the gaps between the joist and subfloor that cause floor squeaks. The WSNTL screw countersinks easily and backs out smoothly, allowing for easy future access to floor cavities.
