This is a \u003cstrong\u003eheavy tension tie\u003c\/strong\u003e designed for \u003cstrong\u003eresisting tension loads in post-pour wood-to-concrete connections\u003c\/strong\u003e. Model Number: \u003cstrong\u003eHTT4\u003c\/strong\u003e. If you are tying framing back to concrete and need a connector built specifically for uplift and pull forces, this is the piece doing that job.\u003c\/p\u003e\n      \u003cp\u003eWhat matters here is not just that it is heavy steel, but how it is formed. Simpson built the HTT4 with an optimized nailing pattern and a four-fold seat to improve performance and reduce deflection. In plain terms, that means the connector is designed to stay more stable under load instead of giving up movement where you do not want it. On structural hardware, that kind of detail is the difference between a part that merely fits and one that is engineered for the load path.\u003c\/p\u003e\n      \u003cp\u003eThe HTT4 is made from 11-gauge steel and comes in a zinc galvanized G90 finish. Its 2-1\/2 inch width and 12-3\/8 inch length make it a good fit when you need a tall fastening area into the wood member while still landing onto an anchor point at the base. The formed seat and tapered side geometry help the connector carry force down into the anchor location cleanly. This is also a single-piece formed connector, so you are not dealing with a riveted assembly.\u003c\/p\u003e\n      \u003cp\u003eInstallation flexibility is a big reason this connector gets specified. The HTT series is suitable for retrofit or new construction projects, and it can be installed with cast-in-place or post-installed anchor bolts. That gives contractors options depending on whether the foundation is already in place or the work is being planned from the ground up. Simpson also notes that when installing over wood structural panel sheathing, a 2-1\/2 inch long fastener minimum should be used.\u003c\/p\u003e\n      \u003cp\u003eAnother practical point is hardware simplification. The Simpson Strong-Tie HTT4 Heavy Tension Tie does not require washers in the standard connection described by the manufacturer. That cuts one more part out of the process and helps speed up installation planning. For crews doing repeated holdown and uplift-resistance work, little details like that add up fast.\u003c\/p\u003e\n      \u003cp\u003eThis connector is a strong fit for framers, general contractors, remodelers, and builders working in high-wind construction or any application where wood framing needs to be positively tied back to concrete. It is especially useful in jobs where retrofit capability matters, since the design supports post-pour conditions instead of assuming everything was cast around the hardware from day one. If you are looking for a structural connector for fastening, uplift resistance, and wood-to-concrete anchoring, the HTT4 is a purpose-built option rather than a generic bracket trying to do structural work.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails id=\"product-benefits-1\" class=\"acc\"\u003e\n    \u003csummary\u003e\u003ch2\u003eDesigned for Real Wood-to-Concrete Connections\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\/mii9ejfa3n\/jpeg\/C_HTT4_InstIll_Ill_Instld_TensionTie-Truss_C0.jpeg?position=c\u0026amp;color=ffffffff\u0026amp;u=cjmyin\" alt=\"Simpson Strong-Tie HTT4 Heavy Tension Tie installed in a wood framing to concrete connection at a structural post base in a construction detail\" class=\"tnblock-img\"\u003e\n        \u003c\/div\u003e\n        \u003cdiv class=\"copy\"\u003e\n          \u003cp\u003eThis is the kind of connector you use when the load path matters.
