Description

Key Features

Deep Reach Access

The deep socket body helps you reach nuts on longer studs and recessed fasteners where a standard socket comes up short.

Better Fastener Grip

DirectTorque technology is built to reduce fastener rounding and keep a more secure hold when you are breaking hardware loose or tightening it down.

Built for Repeated Use

Chrome vanadium steel, a polished finish, and hard-stamped markings give this DeWalt deep impact socket the durability and visibility you want in a frequently used size.

Overview

The DeWalt 16 mm 3/8 Inch Drive 6-Point Metric Deep Impact Socket, model DWMT88825OSP, is a single deep metric socket made for mechanics, technicians, and anyone doing regular equipment or vehicle service. This is a deep impact socket designed for fastening and loosening 16 mm metric fasteners with a 3/8 inch drive ratchet or impact tool. If 16 mm is one of your common sizes, this is the kind of socket you keep close because it gives you the reach and grip needed for real repair work, not just bench-top assembly.

The main advantage here is the combination of a deep profile and a 6-point opening. The deep design gives you clearance over longer studs and recessed hardware, which matters when a shallow socket will not seat fully. The 6-point shape is the right choice when you want better contact on the flats of the fastener instead of stressing the corners. That is especially useful on stubborn or partially worn metric nuts and bolts.

DeWalt also builds this socket with DirectTorque technology. In plain terms, that means the socket is designed to grip fasteners in a way that helps reduce rounding. On the job, that can save you from turning a simple service task into an extraction problem. Whether you are working on suspension hardware, brackets, machinery guards, or general maintenance fasteners, a socket that holds better is worth having.

The chrome vanadium steel construction gives the socket the strength expected from a shop-grade hand tool, while the polished finish helps protect against chipping and flaking. That matters if the socket lives in a toolbox, rolls around in a service cart, or gets used in dirty environments where tools are constantly being handled. The hard-stamped markings are another practical touch. Size markings that stay readable are a lot better than markings that disappear after a few months in the drawer.

There is also a knurled control ring for better handling. That may sound like a small detail, but it makes a difference when your hands are oily, gloved, or moving fast through a socket set during repeated work. It is the kind of feature you notice when you are swapping sockets often and do not want to fumble with slick chrome.

In terms of fit, this socket uses a 3/8 inch drive, which puts it right in the sweet spot for a lot of automotive, maintenance, and general repair tasks. It is compact enough for common ratchet work but still suited to many medium-duty fasteners where a 1/4 inch drive would be undersized. Because it is metric and sized at 16 mm, it is best for users who work on imported vehicles, modern equipment, and assemblies where metric hardware is standard.

If you are a DIYer putting together a reliable set of frequently used metric sockets, this is a smart size to add. If you are a pro tech or maintenance guy, it is a straightforward replacement or fill-in piece that covers a common fastener size with the reach of a deep socket. No fluff here: it is a purpose-built DeWalt socket meant to grip well, read clearly, and hold up to regular service work.

Reach Fasteners a Standard Socket Cannot

This socket is built for the jobs where extra depth actually matters. When a nut sits down on a stud or hardware is recessed inside a bracket, the deep body gives you the access to get fully seated and get the work done cleanly.

• 16 mm metric size for common service and repair fasteners
• 3/8 inch drive fits standard ratchets and many impact-ready drive tools
