Key Features

Deep Reach

This deep socket gives you the extra clearance you need when nuts sit on long studs or threaded rod. That makes it a better fit for automotive and mechanical work than a standard shallow socket.

3/8 in Drive Fit

Built for 3/8 inch drive ratchets and extensions, this socket lands in the sweet spot for common service work. It is a practical size for mechanics who want control without stepping up to a larger drive.

Grip and Durability

The DeWalt deep socket uses chrome vanadium steel for strength and includes knurled rings to help reduce hand slippage. That matters when your hands are oily and you still need to start fasteners cleanly.

Overview

The DeWalt DWMT88986OSP Mechanics 6 Point 3/8″ Drive Deep Socket 7/16″ is a single SAE deep socket made for turning 7/16 inch fasteners with a 3/8 inch drive ratchet or extension. This is a deep socket designed for fastening and removal work where extra depth is needed to clear longer studs or reach recessed nuts. Model Number: DWMT88986OSP.

What makes this socket useful is pretty simple: the 7/16 inch size is common enough to earn a spot in any mechanic’s drawer, and the deep pattern gives you more room to work when hardware sits past the end of a standard socket. If you work on automotive components, equipment, small engines, or general shop repairs, that extra length saves time because you are not stopping to swap tools when a shallow socket runs out of room.

This DeWalt socket uses a 6 point opening, which is the right call when you want solid contact on the flats of the fastener. For real shop use, that means a more secure grip on nuts and bolts than a loose-fitting setup, especially when the hardware has seen some age. It is built from chrome vanadium steel, so the focus here is strength and day-to-day durability rather than gimmicks.

DeWalt also adds knurled beauty rings to reduce hand slippage. That sounds like a small detail until you are grabbing a socket with greasy fingers at the bench or under the hood. It gives you a little more control when starting the socket by hand before putting it on a ratchet, and that helps speed up repetitive fastening work.

Because this is a single-piece socket and not part of a large bundled set, it makes sense for replacing a missing size, filling a gap in your current kit, or building out a custom 3/8 inch drive setup one piece at a time. That is especially useful for techs and serious DIYers who know exactly which sizes get used and do not want to pay for filler pieces they will never touch.

If you need one dependable SAE deep socket for a 3/8 inch drive system, this one is aimed at mechanics, maintenance techs, garage users, and anyone doing regular fastening work on equipment with exposed threads or recessed hardware. It is not trying to be flashy. It is a straightforward DeWalt hand tool that covers a common size, fits a common drive, and solves a common problem.

Reach Past Exposed Threads

A deep socket earns its keep when standard sockets cannot fully seat over longer hardware. This one gives you the clearance needed to work on nuts that sit down on studs without fighting the tool.

Pro Tip

Use a deep socket like this when the nut sits on a stud with extra thread showing. It saves you from only catching the edge of the fastener with a shallow socket, which is an easy way to round hardware when you are working fast.
