Simpson Strong-Tie MTH Wood Underlayment Screw (Collated), Yellow Zinc #7 x 1 in. Yellow Zinc, MTHZ1S, Box (2,500 pcs)
The MTH Underlayment screw is designed for fast and secure underlayment to subfloor installations. Unlike nails, the MTH Underlayment screw 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.
- Trim head with nibs for easy countersinking
- #2 square drive (driver bit in each box; replacement bit model BIT2S)
- High-low threads
- Sharp point
- Curved collation
