Simpson Strong-Tie MTHZ1S Strong-Drive® MTH Wood Underlayment Screw (Collated) — #7 x 1 in. Yellow Zinc (2500-Qty)

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.

This Simpson product is designed for construction, connector, fastening, anchoring, and structural applications where dependable performance, durability, and jobsite-ready installation matter.
