Key Features

Better Fastener Grip

DirectTorque technology is built to help prevent rounding fasteners. That matters when you are working with small metric hardware where a damaged head can slow the whole job down.

Deep Socket Reach

The deep socket design gives extra clearance for longer bolts and studs. It is a better fit when a standard shallow socket will not seat fully over the fastener.

Built for Repeated Use

Chrome vanadium steel, a polished finish, and hard-stamped markings give this DEWALT socket the durability and readability you want in a small 1/4 inch drive socket that gets used often.

Overview

The DEWALT 4 mm 1/4 Inch Drive 6-Point Metric Deep Impact Socket is a metric deep socket made for turning 4 mm fasteners with a 1/4 inch drive ratchet or extension. This is a deep socket designed for fastening and mechanical work in tight, detail-focused applications. Model Number: DWMT88935OSP. If you work on small hardware and want a socket that grips well, reaches over longer studs, and stays easy to identify in the drawer, this is the kind of piece you keep close.

The big selling point here is the 6-point opening paired with DEWALT DirectTorque technology. On the job, that means the socket is built to contact the fastener in a way that helps reduce rounding. With small metric hardware, that is not a minor detail. A stripped 4 mm fastener can turn a quick repair into a frustrating one fast, so grip and fit matter more than flashy claims.

The deep profile is what separates this socket from a basic shallow option. It gives you more room for bolts that extend past the nut or for recessed hardware where a standard socket just will not get all the way on. That makes it useful for automotive trim work, small engine service, equipment maintenance, and any task where compact metric hardware sits below the surface or on a stud.

Material matters in hand tools, and this socket is made from chrome vanadium steel. That is a common choice for durable sockets because it balances strength and everyday usability. The polished finish helps resist chipping and flaking, which also makes the socket easier to wipe clean after greasy or dirty work.

DEWALT also adds practical touches that make a difference over time. The hard-stamped markings are there so size identification stays readable longer than lightly marked alternatives. The knurled control ring gives you a little more grip when you are starting the socket by hand or pulling it out from a tight tray or rail.

This socket makes the most sense for mechanics, maintenance techs, and serious DIY users who already work within a 1/4 inch drive hand tool setup and need a specific 4 mm metric deep socket instead of a generic assortment piece. If you want a single replacement socket or need to fill a missing size in your set, this is a straightforward, job-ready DEWALT option.

This DEWALT 4 mm 1/4 Inch Drive 6-Point Metric Deep Impact Socket is sized for small metric hardware where fit and control matter. The deep body helps it seat over longer bolts and recessed fasteners without forcing you to switch to a different tool setup.
