Underlayment and Subfloor Solutions
Simpson Strong-Tie, the leader in commercial and home building solutions for more than 60 years, is providing a comprehensive set of fasteners designed for interior applications and to improve your installation of cement backerboard, subfloor and underlayment materials. The Cement Board screw, MTH Underlayment screw and Strong-Drive® WSV Subfloor screw are designed to give the user what they need to do the job right. These fasteners are equipped with sharp points and deep-recessed heads to make installations fast and easy with fewer cam-outs. Their thread design ensures that your materials are held together tightly and create a more uniform foundation for tile, counters, backsplashes or floor coverings.
Cement Board Screw
Designed for use with all cement backerboards including HardieBacker®, Durock®, WonderBoard® and PermaBase®.
The ANSI A108-compliant Cement Board screw is designed for ease of installation and long life. With its corrosion-resistant coating, the Cement Board screw is ideal for use with all tile backerboards.
MTH Underlayment Screw
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® WSV Subfloor Screw
For Subfloor and Sheathing Applications
The Strong-Drive WSV Subfloor screw is the only fastener to be dual-evaluated under ICC-ES AC233 and AC120 for wood-frame subfloor fastening. Redesigned tip and thread pattern provides easy starts and up to 25% less torque while driving—makes for up to 20% faster driving. With lateral, shear and withdrawal values that exceed those of 10d common nails, the holding power of the WSV Subfloor screw eliminates the gaps between the joist and subfloor that cause floor squeaks. The WSV Subfloor screw countersinks easily and backs out smoothly, allowing for easy future access to floor cavities.
