This is a \u003cstrong\u003estrap tie holdown designed for transferring uplift and overturning loads from the wall into concrete\u003c\/strong\u003e. Model Number: \u003cstrong\u003eSTHD14\u003c\/strong\u003e. If you are tying a wall system down to a concrete foundation and need a cast-in-place connector with more load capacity than a basic strap, this is the kind of hardware you spec.\u003c\/p\u003e\n      \u003cp\u003eWhat makes the STHD series different is the way it is shaped for the pour. Simpson calls out enhanced stability before and during concrete placement, which matters because movement during the pour can throw off alignment and create headaches when the wall goes up. The fastener pattern is also laid out to allow fastening at the edges of back-to-back studs, which is useful in wall assemblies where fastening space is tight and connector placement is not forgiving.\u003c\/p\u003e\n      \u003cp\u003eThe STHD14 is made from \u003cstrong\u003e12-gauge steel\u003c\/strong\u003e with a \u003cstrong\u003ezinc galvanized G90 finish\u003c\/strong\u003e. In practical terms, that gives you a formed steel connector with the stiffness needed for structural anchorage and the corrosion protection expected for standard galvanized framing hardware. The strap is \u003cstrong\u003e3 inches wide\u003c\/strong\u003e and \u003cstrong\u003e26-1\/8 inches long\u003c\/strong\u003e, so it gives you a substantial fastening area along the stud line while keeping the connector format straightforward for layout and inspection.\u003c\/p\u003e\n      \u003cp\u003eBelow the embedment line, the connector uses slots that help increase front-to-back concrete bond and help reduce spalling. That is not just a shape detail. It affects how the connector behaves once the concrete cures, especially in real foundation work where edge conditions, corner conditions, and pour quality all affect the finished result. Simpson also notes that STHD10 and STHD14 can achieve full loads for spalls less than 4 inches in the installation conditions they describe, which is useful jobsite context when evaluating minor concrete damage near the strap.\u003c\/p\u003e\n      \u003cp\u003eFor installation, Simpson specifies using all required fasteners, installing the strap plumb, and fastening the strap from the bottom up. The connector is intended to be installed before the concrete pour, typically with a StrapMate or similar holding device to keep it positioned. That makes this a product for planned foundation work, not a last-minute retrofit part. If your workflow depends on predictable placement before the pour, that is exactly where this connector fits.\u003c\/p\u003e\n      \u003cp\u003eThe STHD14 is specifically meant for \u003cstrong\u003econcrete applications\u003c\/strong\u003e. It is not part of a battery platform or tool system, but it is part of Simpson Strong-Tie's structural connector lineup for holdowns and tension ties. That matters if you are working from engineered details or matching other Simpson connection hardware across the job, because the naming, sizing, and load-table structure stay consistent within the system.\u003c\/p\u003e\n      \u003cp\u003eWho should buy it? This is for engineers, framers, foundation crews, and contractors building shearwalls or other structural wall assemblies that call for an embedded strap tie holdown. It is also a strong fit for code-driven residential and light commercial construction where the hardware schedule is already calling out Simpson holdown models by part number. If your plans specify \u003cstrong\u003eSTHD14\u003c\/strong\u003e, this is the exact connector category you want, and the size, gauge, finish, and concrete-use design are what make it job-correct.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails id=\"product-benefits\" class=\"acc\"\u003e\n    \u003csummary\u003e\u003ch2\u003eKeeps the Strap Positioned During the Pour\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\/kfro83gg3l\/jpeg\/C_STHD_InstPho_Pho_Instld_StrapTieHoldown-wStrapMate_C0.jpeg?position=c\u0026amp;color=ffffffff\u0026amp;u=cjmyin\" alt=\"Simpson Strong-Tie STHD14 Strap Tie Holdown positioned plumb on framing with a holding device before concrete placement on a structural wall layout\" class=\"tnblock-img\"\u003e\n        \u003c\/div\u003e\n        \u003cdiv class=\"copy\"\u003e\n          \u003cp\u003eThis connector is meant to be set before the pour, and the design is aimed at staying where you put it.
