Key Features

3/8 Inch Drive Fit

This socket is built for 3/8 inch drive ratchets and extensions, which makes it a go-to size for general mechanical service and everyday fastener work.

Chrome Vanadium Build

Premium chrome vanadium steel gives the socket the strength and durability you want when you are leaning on stubborn hardware instead of babying the tool.

Better Grip by Hand

Knurled beauty rings help reduce hand slippage, which makes it easier to start the socket on an extension or pull it from a drawer with greasy hands.

Overview

The DeWalt DWMT88979OSP Mechanics 6 Point 3/8″ Drive Socket 9/16″ is a single SAE socket made for mechanics and anyone working with common hex fasteners. This is a socket designed for fastening and loosening 9/16 inch nuts and bolts with a 3/8 inch drive ratchet or extension. Model Number: DWMT88979OSP.

The size and drive combination put this socket right in the middle of a lot of routine repair and maintenance work. A 9/16 inch socket is a common SAE size, and the 3/8 inch drive format keeps it practical for hand tools used in automotive service, equipment maintenance, and general shop work.

DeWalt builds this socket from premium chrome vanadium steel, which matters because a socket like this lives through repeated load cycles, drawer impacts, and daily use on steel fasteners. The material choice is about durability first, especially for a hand tool that gets used over and over on the same types of jobs.

This is a 6-point socket, which is the right call when you want stronger contact on the flats of a fastener instead of loading the corners more aggressively. That makes it a smart option for mechanics and maintenance techs dealing with standard hex hardware where control and fit matter more than speed alone.

DeWalt also adds knurled beauty rings to reduce hand slippage. That is a small detail, but it helps in real use when your hands are oily, you are working out of a crowded toolbox, or you need to start the socket onto an extension without fumbling it.

If you need one everyday SAE socket for a 3/8 inch drive setup, this one makes sense for automotive work, shop service, and general repair. It is straightforward, durable, and sized for a very common fastening task without adding anything you do not need.
