Description

Key Features

Deep Reach

The deep socket body gives you extra clearance for longer fasteners and recessed nuts where a standard socket can come up short.

Chrome Vanadium Build

Made from chrome vanadium steel for the strength and durability you want in a shop socket that gets used regularly.

DeWalt Deep Socket Control

Knurled beauty rings help reduce hand slippage, which matters when you are starting or removing fasteners by hand before putting the ratchet to work.

Overview

The DeWalt DWMT88985OSP Mechanics 6-Point 3/8 in. Drive Deep Socket 3/8 in. is a single SAE deep socket built for fastening and removal work with a 3/8 inch drive ratchet or extension. This is a deep socket designed for reaching recessed fasteners and working over longer studs or bolts. Model Number: DWMT88985OSP.

The key detail here is the combination of a 3/8 inch drive and a 3/8 inch SAE socket size in a deep pattern. That makes it a practical fit for automotive work, equipment maintenance, shop tasks, and general mechanical fastening where a shallow socket does not give you enough reach. The 6-point design is a smart choice for solid engagement on hex fasteners because it is built around the flats of the nut or bolt rather than a broader multi-point fit.

DeWalt builds this socket from chrome vanadium steel, which is the material most buyers want in a hand-tool socket that needs to hold up to repeated use. If you are stocking a box one size at a time or replacing a socket that goes missing because it gets used constantly, material quality matters more than gimmicks. Chrome vanadium gives this socket the durability expected for regular ratchet work in the garage or on the job.

One feature worth calling out is the knurled beauty ring. That may sound small, but it is the kind of detail you notice when your hands are oily, gloved, or working in a tight spot. It gives you a better grip when you need to spin the socket by hand onto a fastener or back it off before switching to a ratchet. That saves a little fumbling, and on repetitive fastening work that is exactly the kind of small improvement that matters.

Because this is a single-piece socket and not part of a large set, it makes the most sense for mechanics, technicians, and serious DIY users who want to fill a missing size, build out a custom socket rail, or keep frequently used SAE sizes close at hand. If your work involves 3/8 inch hex fasteners and you prefer the access of a deep socket, this is a straightforward, no-nonsense addition to the box.

Reach Fasteners a Standard Socket Misses

The deep socket format is the whole reason to buy this version instead of a shallow one. It gives you the extra length needed for nuts sitting lower in a pocket or for bolts with more thread sticking through.

DeWalt DWMT88985OSP Deep Socket That Covers the Basics Right

If you need a single 3/8 inch SAE deep socket that is easy to grip, durable, and ready for regular ratchet work, this one makes sense.

• Who it’s for: Mechanics, techs, and DIY users replacing a missing socket or building out a practical SAE socket lineup.
• Why it stands out: The deep reach, 6-point fit, chrome vanadium construction, and knurled ring are the features that actually matter in day-to-day use.
• Worth knowing: This is a single socket, not a set, so it is best for filling a specific size gap rather than starting from scratch.
