This is a \u003cstrong\u003ecollated wood screw designed for wood underlayment to wood installation\u003c\/strong\u003e. Model Number: \u003cstrong\u003eMTH114S\u003c\/strong\u003e. If you are working on flooring prep, subfloor overlay, or modular construction where speed and a flush finish matter, this screw is built for that job.\u003c\/p\u003e\n    \u003cp\u003eAt the business end, Simpson uses a sharp point to get the screw started quickly, plus high-low threads to pull the underlayment down tight. That tighter pull matters because underlayment work is not just about holding sheets in place. It is about reducing movement between layers, which helps cut down on the squeaks and pull-out problems that can show up later under finished flooring.\u003c\/p\u003e\n    \u003cp\u003eThe head design is what separates this fastener from a basic wood screw. The trim head includes nibs for easier countersinking, so the screw can finish more cleanly at the surface instead of leaving a proud head that telegraphs through floor coverings. For underlayment work, that is a real advantage because a flatter finished surface gives you a better base for vinyl, laminate, engineered flooring, or other finish materials that do not forgive bumps.\u003c\/p\u003e\n    \u003cp\u003eThis MTH fastener also uses curved collation for use with the Quik Drive system. In plain terms, that means it is set up for fast repeated driving with a compatible collated screw tool instead of loading loose screws one at a time. On larger jobs, that saves time, keeps spacing consistent, and makes the whole fastening process more efficient than hand-driving individual screws.\u003c\/p\u003e\n    \u003cp\u003eThe screw itself is a \u003cstrong\u003e#7 x 1-1\/4 in.\u003c\/strong\u003e gray phosphate collated fastener with a \u003cstrong\u003eSquare #2 drive\u003c\/strong\u003e, \u003cstrong\u003etrim head\u003c\/strong\u003e, and \u003cstrong\u003esharp point\u003c\/strong\u003e. Gray phosphate coating is commonly used for interior applications, which lines up with the intended use here. This is not a general exterior deck screw pretending to be an underlayment fastener. It is a purpose-built interior flooring screw meant to do one job well.\u003c\/p\u003e\n    \u003cp\u003eCompatibility is straightforward. Simpson lists the MTH114S for use with the \u003cstrong\u003eQuik Drive PRO200SG2\u003c\/strong\u003e, and supplementary load-table data also references \u003cstrong\u003ePRO200\u003c\/strong\u003e and \u003cstrong\u003ePRO200S\u003c\/strong\u003e compatible Quik Drive tools. If you already run the Quik Drive fastening platform, this screw drops right into that workflow. A driver bit is also listed as included in each box, with replacement bit model \u003cstrong\u003eBIT2S\u003c\/strong\u003e.\u003c\/p\u003e\n    \u003cp\u003eThe pack size is another reason this product makes sense for production work. With \u003cstrong\u003e2,500 collated screws per box\u003c\/strong\u003e, the Simpson Strong-Tie MTH114S Strong-Drive MTH Wood Underlayment Screw is aimed at contractors, remodelers, flooring installers, and serious DIY users doing full-room or full-level installs, not a tiny patch repair. If you need repeatable fastening, good pull-down, and a head that finishes clean in underlayment, this is the right style of screw for the job.\u003c\/p\u003e\n  \u003c\/div\u003e\n\u003c\/details\u003e\n\n\u003cdetails id=\"product-benefits-1\" class=\"acc\" open\u003e\n  \u003csummary\u003e\u003ch2\u003eDesigned to Sit Clean in Underlayment\u003c\/h2\u003e\u003c\/summary\u003e\n  \u003cdiv class=\"acc-body\"\u003e\n    \u003cdiv class=\"row\"\u003e\n      \u003cdiv class=\"img\"\u003e\n        \u003cimg src=\"https:\/\/ssttoolbox.widen.net\/content\/vkdrpffrau\/jpeg\/F_MTH114_InstPho_Pho_Inst_MTH-UnderlaymentScrew-GrayPhosphate-Underlayment_C0.jpeg?position=c\u0026amp;color=ffffffff\u0026amp;u=cjmyin\" alt=\"Simpson Strong-Tie MTH114S Strong-Drive MTH Wood Underlayment Screw being driven into wood underlayment over OSB subfloor during flooring installation\" class=\"tnblock-img\"\u003e\n      \u003c\/div\u003e\n      \u003cdiv class=\"copy\"\u003e\n        \u003cp\u003eThis screw is made for the kind of fastening where surface quality matters as much as holding power.
