Strong, functional, and as durable as you can ask for, Stanleys DWMT86324OSP Deep 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 Deep Socket is hard, tough, and never brittle. 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 Stanley DWMT86324OSP is a 6-point socket with a 12 mm socket size and a 3/8" drive size. With thicker walls, it does not flex, which 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!
