Key Features

Better Fastener Grip

DirectTorque technology helps reduce fastener rounding and gives the socket a more secure hold where it matters most.

Deep Socket Reach

The deep impact socket design gives you extra reach over studs and longer fasteners, which makes it more useful for repair and assembly work.

Built for Control

Chrome vanadium steel, hard stamped markings, and a knurled control ring make this socket easier to identify and handle at the bench or on the job.

Overview

The DEWALT 7/8 Inch – 3/8 Inch Drive 6-Point Imperial Deep Impact Socket is a single SAE deep socket built for gripping 7/8 inch fasteners with a 3/8 inch drive ratchet or impact setup. This is a deep impact socket designed for fastening and loosening hex fasteners in automotive, equipment, and general mechanical work. Model Number: DWMT88984OSP.

What makes this socket worth paying attention to is DEWALT’s DirectTorque technology. That matters because the contact points are designed to help prevent rounding on stubborn or worn fasteners while giving you a better grip under load. On the job, that means less slipping and a better chance of getting hardware loose without chewing it up.

The 6-point opening is the right call for users who want solid engagement on hex fasteners. Compared to higher-point sockets, a 6-point design puts the load where the fastener can handle it better, which is especially useful when you’re working with tighter hardware, corrosion, or repeated service cycles.

This socket is made from chrome vanadium steel and finished with a polished surface to help resist chipping and flaking. DEWALT also adds hard stamped size markings, which is a practical feature that gets appreciated once the socket has been in a drawer, bag, or service cart for a while. You can still grab the right size without guessing.

The knurled control ring adds a little extra handling control when your hands are oily or you’re starting a fastener by hand before putting a ratchet on it. That is a small feature, but it makes everyday use easier, especially in garage, shop, and maintenance settings where clean hands are not part of the plan.

If you need a 3/8 inch drive SAE socket for 7/8 inch fasteners and want the added reach of a deep socket, this one makes sense for mechanics, maintenance techs, and serious DIY users who want reliable fit and straightforward durability. It is not a fancy collector’s piece. It is the kind of socket you buy to do real work, find quickly, and keep in rotation.

Reach Longer Fasteners Cleanly

A deep socket earns its keep when standard sockets come up short on protruding studs or recessed hardware. This DEWALT socket gives you the extra depth needed for service work without giving up the control of a 6-point fit.
