Mechanically Galvanized Heavy-Duty Concrete and Masonry Screw Anchor is a carbon steel screw anchor built for heavy-duty anchoring in concrete and masonry. This is a concrete and masonry screw anchor designed for securing fixtures into concrete, brick, and cinder block. Model Number: THD50800HMG. In this size, you get a 1\/2 inch diameter anchor, 8 inch overall length, mechanically galvanized finish, and a 20-piece pack.\u003c\/p\u003e\n    \u003cp\u003eWhat matters on the job is that this anchor is made to install with a standard 1\/2 inch carbide drill bit, so the hole size matches the nominal anchor diameter. That keeps layout and prep straightforward. Simpson Strong-Tie also uses serrated teeth at the tip to help the anchor cut into the base material and reduce installation torque, which can make a real difference when you are driving a larger fastener through a fixture and into cured concrete.\u003c\/p\u003e\n    \u003cp\u003eThe thread geometry is doing the heavy lifting here. Simpson calls out a thread design that undercuts to transfer load efficiently into the base material. In plain terms, that means this anchor is not just filling a hole, it is biting into the concrete in a way that supports demanding structural and heavy-duty attachment work. It is also qualified for static and seismic loading conditions, which tells you it is intended for serious anchoring applications rather than light-duty hanging jobs.\u003c\/p\u003e\n    \u003cp\u003eThis mechanically galvanized version is the one to look at when the application calls for corrosion resistance beyond standard interior-only hardware. The coating meets ASTM B695, Class 65, Type 1. Simpson Strong-Tie positions it for exterior use and some interior pressure-treated wood sill plate applications. If you are fastening treated lumber, post bases, ledgers, seating, holdowns, bracing, or formwork to concrete, that finish and application rating matter.\u003c\/p\u003e\n    \u003cp\u003eFrom a design standpoint, the hex washer head is a practical feature. It does not require a separate washer unless code requires one, which means fewer loose pieces to keep track of and a cleaner install. The head is also stamped for easy identification. For crews managing multiple anchor sizes on site, that small detail helps prevent mix-ups. This anchor is fully removable too, which is useful in temporary installations or when a fixture needs to be repositioned later.\u003c\/p\u003e\n    \u003cp\u003eFor this specific THD50800HMG size, the wrench size is 3\/4 inch, the recommended fixture hole size is 5\/8 inch to 11\/16 inch, and the thread length is 5-1\/2 inches with 3 threads per inch. That combination makes it a good fit when you need added length for thicker fixtures, deeper embedment needs, or assemblies like post bases and ledger attachments where a shorter anchor may not give you enough reach.\u003c\/p\u003e\n    \u003cp\u003eThere are a couple of practical limitations worth knowing. Simpson states these anchors are for one-time use only, since repeated installation can wear the threads and reduce load capacity. They also caution against oversized holes in the base material because that reduces the thread-to-concrete interlock that gives the anchor its hold. If you are installing into hollow CMU, do not use an impact wrench.\u003c\/p\u003e\n    \u003cp\u003eWho should buy this? Contractors, remodelers, concrete crews, deck builders, and serious DIYers working on real anchoring jobs. If you need a heavy-duty screw anchor that installs with standard tooling, handles concrete and masonry, and offers the convenience of removability, this is a strong choice. If your job is light-duty or purely decorative, it is more anchor than you need. But for structural-style fastening and tough base materials, this one earns its space in the truck.\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\u003eDrives Cleanly Into Concrete\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\/xh7vbobnp2\/jpeg\/A_THDMG_InstPho_Pho_Inst_TitenHD-Galvanized-Ledger_C0.jpeg?position=c\u0026amp;color=ffffffff\u0026amp;u=cjmyin\" alt=\"Simpson Strong-Tie Titen HD 1\/2 in. x 8 in.
