Strong, functional, and as durable as you can ask for, Stanleys DWMT75159OSP Impact Socket is a real bargain! Proudly featured are its knurled beauty rings that provide a firmer grip surface, reducing hand slippage. This allows you to hold fasteners in place more securely. Made of chrome vanadium steel, this Stanley Impact Socket is hard, tough, and never brittle. Twisting, breaking, or stripping is unheard of when using it with air and electric wrenches or in any high-torque scenario. In addition, it offers better transmission from tool to fastener. So when facing repair tasks, either minimal or extensive, worry no more about bending and breaking! With its superior quality make, you also have the rust-resistance advantage. This Dewalt DWMT75159OSP has a socket size of 13/16" and a 3/4" drive size. It parades its DirectTorque Technology which provides a better grip and dramatically reduces rounding bolts heads and slippage over the fastener corners. The socket edges are angled back a few degrees which provides more contact area inside the socket and makes it really easy to slide over a fastener. This little man is an indispensable tool for mechanical work involving components, big and small. Fill your tool box with only the best tools! Anyone who has professionally worked with sockets and wrenches knows that Stanley produces the best bang of the buck when it comes to the finest tools in the biz!
