Holdown for Cold-Formed Steel\u003c\/strong\u003e is a steel holdown connector made for anchoring cold-formed steel shearwall framing to the foundation so the wall can resist overturning forces. This is a \u003cstrong\u003eholdown\u003c\/strong\u003e designed for \u003cstrong\u003eshearwall anchorage and uplift resistance in cold-formed steel framing\u003c\/strong\u003e. Model Number: \u003cstrong\u003eS\/HDU6\u003c\/strong\u003e.\u003c\/p\u003e\n      \u003cp\u003eFor this size, the connector body measures 10-3\/8 inches high and 2-3\/8 inches wide, and it is formed from 118 mil, 10 gauge steel. In practical terms, that gives you a compact but serious connector for steel stud work where you need a known holdown geometry instead of trying to piece together a field solution. The G90 galvanized coating adds corrosion protection for standard jobsite conditions, and the product is specifically listed for high-wind construction.\u003c\/p\u003e\n      \u003cp\u003eWhat separates the S\/HDU series from a basic bent bracket is the pre-deflected geometry. Simpson Strong-Tie calls out that this shape virtually eliminates material stretch, which helps produce lower deflection under load. That matters on a shearwall because movement at the anchorage point adds up fast. Less stretch means a tighter, more predictable connection at the base of the wall.\u003c\/p\u003e\n      \u003cp\u003eThe form factor is built around cold-formed steel framing, not wood framing. The holdown is specially designed to fit inside the open side of the stud, which keeps the connector tucked into the framing cavity instead of hanging out where it can interfere with adjacent components. For installers, that means cleaner integration with steel studs and better access to the specified screw pattern.\u003c\/p\u003e\n      \u003cp\u003eInstallation details matter here. Simpson Strong-Tie specifies using standard #14 self-drilling screws to fasten the connector to studs, and it also notes that all specified fasteners must be used. The anchor bolt washer is not required, and a crescent washer is included with the holdown. If you are coordinating anchorage, Simpson points users toward SABR and PAB anchor bolts for cast-in-place anchorage options, and SET-3G and AT-3G adhesive products for retrofit anchor bolt applications.\u003c\/p\u003e\n      \u003cp\u003eThis connector also gives you flexibility depending on how the project is engineered. The published information includes use in conventional screw-fastened cold-formed steel framing and references allowable uplift loads for welding to cold-formed steel stud and structural steel. That gives designers and installers a path when the job calls for a welded connection strategy instead of standard screw-only attachment.\u003c\/p\u003e\n      \u003cp\u003eOn the job, this is the kind of hardware that gets chosen by engineers, framers, and specialty contractors who do not want guesswork at the base of a shearwall. It is best suited for cold-formed steel wall systems in commercial, multifamily, institutional, and other steel-framed projects where overturning restraint is part of the structural design. If you are building with steel studs and need a purpose-built holdown rather than adapting general hardware, this is exactly the lane for the S\/HDU6.\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\u003eFits Cleanly Inside Steel Stud Framing\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\/si1vjr3o4c\/jpeg\/CF_S-HDU11_InstPho_Pho_Instld_Holdown_C0.jpeg?position=c\u0026amp;color=ffffffff\u0026amp;u=cjmyin\" alt=\"Simpson Strong-Tie S\/HDU6 S\/HDU 10-3\/8 in.
