Type 316 SS Countersunk Head Heavy-Duty Screw Anchor, 25-Pack is a heavy-duty screw anchor for anchoring fixtures into concrete and masonry where you need a flush finish and strong hold. This is a heavy-duty screw anchor designed for flush-mount anchoring in concrete and masonry. Model Number THD37400CS6SS. If you are fastening brackets, frames, or other hardware that cannot have a hex head sticking proud of the surface, this anchor is built for that job.\u003c\/p\u003e\n    \u003cp\u003eAt 3\/8 in. diameter by 4 in. long, this anchor gives you a substantial mechanical connection for demanding installations. The hole size matches the anchor diameter, so you drill with a 3\/8 in. carbide bit instead of chasing a special size. That saves time on layout and setup, especially when you are doing multiple anchors in a row. Simpson also rates this Titen HD family for static, wind, and seismic loading conditions, and the product is tested in accordance with ACI 355.2, AC193, and AC106.\u003c\/p\u003e\n    \u003cp\u003eThe countersunk head is the big reason to choose this version over a standard hex-head anchor. It lets the fastener sit flush against the fixture, which is useful for door frames, brackets, plates, and exposed hardware where a raised head would get in the way or look sloppy. The T50 6-lobe drive also matters more than it sounds. It helps reduce driver-bit cam-out during installation, so you spend less time fighting the bit under load and less time cleaning up damaged recesses.\u003c\/p\u003e\n    \u003cp\u003eMaterial is where this specific model separates itself from basic anchors. THD37400CS6SS is made from Type 316 stainless steel, which is the right move when corrosion resistance is a real concern. If the jobsite, environment, or application calls for better long-term resistance than carbon steel or basic plating can offer, this version is the safer pick. It also uses serrated tip teeth to help cut into the base material and reduce installation torque, which makes driving smoother when conditions are right.\u003c\/p\u003e\n    \u003cp\u003eOn the job, this anchor is practical. It is removable, so it works well for temporary anchoring or applications where fixtures may need to be moved later. Installation is simple: drill the hole to size, clean it as required, insert the anchor through the fixture, and tighten until the countersunk head contacts the fixture. For this 3\/8 in. size, the recommended fixture hole size is 1\/2 in. to 9\/16 in., and minimum hole depth overdrill is 1\/4 in. Each box includes the driver bit, so you are not hunting for the correct bit when the package shows up.\u003c\/p\u003e\n    \u003cp\u003eThis anchor makes the most sense for contractors and serious DIY users working in construction, mechanical, electrical, plumbing, remodeling, and structural hardware installation. If your application needs a flush-mount profile, dependable concrete anchoring, and better corrosion resistance, this is a smart version of the Titen HD line to buy. If you only need a cheap interior anchor, there are lower-cost options. If you need stainless, removable performance, and a clean finished install, this is the one that earns its keep.\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\u003eFlush Finish for Clean Hardware Installs\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\/k3gttof9qd\/jpeg\/A_THDCS_InstPho_Pho_Inst_TitenHD-CountersunkHead-Bracket_C0.jpeg?position=c\u0026amp;color=ffffffff\u0026amp;u=cjmyin\" alt=\"Simpson Strong-Tie Titen HD 3\/8-in. x 4-in.
