(13mm) Drive 6-Point 21mm Metric Deep Impact Socket is an individual deep impact socket made for driving and removing 21 mm fasteners with an impact wrench or other 1\/2 inch drive setup. This is a deep impact socket designed for high-torque fastening and removal work. Model Number: DWMT73951OSP.\u003c\/p\u003e      \u003cp\u003eIf you work on suspension hardware, lug-adjacent fasteners, machinery, or any assembly with longer studs, the deep profile matters. It gives you the reach a shallow socket cannot, which means less fighting recessed nuts and less swapping around trying to make the tool fit the job.\u003c\/p\u003e      \u003cp\u003eDeWalt uses a 6-point opening here, which is the right call for impact work. A 6-point socket puts force on the flats of the fastener instead of chewing up the corners. Paired with DirectTorque technology, this socket is built to help prevent rounding and maintain better grip when torque loads climb.\u003c\/p\u003e      \u003cp\u003eJobsite usability is simple but important on a piece like this. The size marking is shown in large font for quicker identification, which saves time when you are sorting through sockets in a drawer, bag, or stacking case. On repetitive fastening work, that small detail matters more than people think.\u003c\/p\u003e      \u003cp\u003eThis DeWalt impact socket is sold as an individual piece, so it makes sense for the user who needs one exact replacement size or wants to fill a gap in an existing socket lineup instead of buying a full set. The official product data identifies it as a 1\/2 inch drive, 21 mm, deep, 6-point metric impact socket with a one-piece count.\u003c\/p\u003e      \u003cp\u003eWho should buy it? Mechanics, equipment techs, general contractors, farm and fleet users, and serious DIYers who already run impact tools and need a dedicated 21 mm metric deep socket. If that is a common size in your work, buying the single DeWalt DWMT73951OSP 1\/2-In. (13mm) Drive 6-Point 21mm Metric Deep Impact Socket is a practical way to get the exact fit you need without paying for extra pieces you will not use.\u003c\/p\u003e    \u003c\/div\u003e  \u003c\/details\u003e  \u003cdetails id=\"product-benefits\" class=\"acc\"\u003e    \u003csummary\u003e\u003ch2\u003eBuilt to Reach Recessed Fasteners\u003c\/h2\u003e\u003c\/summary\u003e    \u003cdiv class=\"acc-body\"\u003e      \u003cdiv class=\"row\"\u003e        \u003cdiv class=\"img\"\u003e          \u003cimg src=\"https:\/\/cdn.anglera.com\/assets\/74d6ed76-fe0d-4d23-a9db-1f8749ca9ef2\/20260526222_1.jpg\" alt=\"DeWalt DWMT73951OSP deep impact socket with 21 mm marking for fastening and removal work on recessed nuts and long-stud applications\" class=\"tnblock-img\"\u003e        \u003c\/div\u003e        \u003cdiv class=\"copy\"\u003e          \u003cp\u003eThe DeWalt DWMT73951OSP deep impact socket is made for the situations where a standard socket will not reach far enough.
