Key Features

3/8 Inch Drive Fit

Built for 3/8 inch drive ratchets, extensions, and breaker bars, this socket covers a common size without taking up extra room in the box.

Chrome Vanadium Build

The chrome vanadium steel construction is there for one reason: better strength and durability when you are leaning on fasteners day after day.

Better Grip by Hand

Knurled beauty rings help reduce hand slippage, which matters when you are starting a fastener by hand or working with oily fingers.

Overview

The DeWalt DWMT86313OSP Mechanics 6 Point 3/8 Inch Drive Socket 18 MM is a metric hand socket made for turning 18 millimeter fasteners with a 3/8 inch drive ratchet or extension. This is a socket designed for fastening and loosening hex fasteners in automotive, equipment, and general mechanical work. Model Number: DWMT86313OSP.

The 6-point design matters because it puts contact on the flats of the fastener instead of crowding the corners. That is the right choice when you want a more secure fit on stubborn bolts and nuts, especially on worn hardware where rounding a fastener can turn a quick job into a headache.

DeWalt builds this socket from chrome vanadium steel, which is a standard material pros look for in mechanics hand tools because it balances strength and durability. For a single 18 millimeter socket, that means it is built to live in a drawer, socket rail, or service cart and keep coming back into rotation for repeat use.

The knurled beauty ring is a small feature, but it is a useful one. When you are grabbing the socket off the bench, starting it on a fastener by hand, or working with greasy hands, that extra texture gives you a better hold than a smooth wall socket.

This DeWalt mechanic socket is a straightforward piece meant for users who already know exactly what size they need. If you are filling in a missing metric socket, replacing a lost 18 millimeter, or building a working 3/8 inch drive setup instead of buying oversized kits full of filler, this is the practical buy.

It is best suited for mechanics, maintenance techs, contractors, and serious DIY users who want a dedicated 18 millimeter socket for regular service work. If your work leans automotive, equipment maintenance, or general shop repair, a 3/8 inch drive 18 millimeter socket like this is one of those sizes worth having close by.

Pro Tip

If you are working on older or slightly worn 18 millimeter hardware, reach for the 6-point socket first. It grabs the flats better than a 12-point style and gives you a better shot at breaking the fastener loose without rounding it off.
