Description

Key Features

Deep Reach

The deep socket profile gives you the extra clearance needed for nuts on longer studs and recessed fasteners. That matters when a standard socket comes up short.

6-Point Grip

The 6-point design and DirectTorque technology are built to grab the flats of the fastener more securely. That helps reduce rounding on stubborn metric hardware.

DEWALT Deep Socket Build

Chrome vanadium steel and a polished finish give this DEWALT deep socket the durability and corrosion resistance you want in a daily-use hand tool.

Overview

The DEWALT DWMT86099OSP 11 mm 1/4 Inch Drive 6-Point Metric Deep Socket is a single deep metric socket made for turning 11 mm fasteners with a 1/4 inch square drive ratchet or extension. This is a deep socket designed for fastening and removal work on nuts and bolts, especially where the fastener sits on a longer stud or below the surface. Model Number: DWMT86099OSP.

What makes this socket useful is not just the size. The deep well design gives you more working depth than a standard socket, so it is the right pick when a regular shallow socket will not fully seat over the nut. If you work on automotive trim hardware, small engine assemblies, equipment covers, brackets, or general mechanical fasteners, that extra depth saves time and keeps you from reaching for adapters or workarounds.

DEWALT uses DirectTorque technology here, which is aimed at improving fastener contact and helping prevent rounded corners. On the job, that means better grip on worn or tight metric fasteners compared to a socket that only bites at the edges. Paired with the 6-point opening, this socket is built for solid engagement on hex fasteners where control matters more than trying to fit a wider range of shapes.

The socket body is made from chrome vanadium steel, a material commonly chosen for hand tools because it balances strength and toughness well. The polished chrome finish helps protect against chipping and flaking while also making cleanup easier after greasy or dirty work. DEWALT also adds hard-stamped size markings, which is a small detail that matters once the socket has been in a box or tray for a while and laser marks would normally start disappearing.

There is also a knurled control ring near the base, which gives you a better grip when starting the socket by hand or pulling it from a tray with oily fingers. That is the kind of feature that sounds minor until you are switching sizes constantly. It makes handling easier without changing how the socket fits on your ratchet.

This socket fits tools and accessories that use a 1/4 inch square drive. That makes it a good match for compact ratchets, spinner handles, and extensions used in tighter spaces or on lighter-duty fastening work. Since it is a metric deep socket, it belongs in any setup where you regularly run into 11 mm hardware and want the cleaner fit of the correct size instead of forcing a close SAE substitute.

If you are building out a mechanic’s drawer, maintaining equipment, or just replacing the one size that always seems to go missing, this is a practical buy. The DEWALT DWMT86099OSP is best for users who want a straightforward 1/4 inch drive deep socket with durable construction, clear markings, and better fastener contact than a basic economy socket.

Reach Nuts on Longer Studs

A deep socket earns its keep when standard sockets cannot fully clear the stud or recessed hardware. This 11 mm socket is built for that exact situation, giving you proper engagement without fighting for reach.

• 11 mm metric size for correctly matched metric fasteners
• 1/4 inch drive fits compact ratchets and extensions

Tool Nut’s Take

Tool Nut’s Take

DEWALT DWMT86099OSP 11 mm 1/4 Inch Drive 6-Point Metric Deep Socket Gets the Basics Right

This is the kind of single socket you buy because you actually need it, and this one brings the right features instead of being a throwaway fill-in piece.

• Who it’s for: Anyone doing light mechanical work, automotive service, equipment repair, or replacing a missing 11 mm deep socket in a 1/4 inch drive setup.
• Why it stands out: The deep profile, 6-point opening, DirectTorque design, and hard-stamped markings make it more useful and easier to live with than a bargain-bin socket.
• Worth knowing: This is a single socket, not a set, and it is built around 1/4 inch drive applications. If you regularly need more leverage, you may want the same size in a larger drive as well.
