Key Features

3/8 In Drive Fit

This DeWalt socket is built for 3/8 inch drive ratchets and extensions, which makes it a practical size for general mechanical fastening and service work.

Chrome Vanadium Build

Premium chrome vanadium steel gives the socket the strength and wear resistance you want in a piece that sees repeated use on stubborn fasteners.

Better Grip By Hand

Knurled beauty rings help reduce hand slippage when you are starting the socket on a fastener or pulling it from a drawer with oily hands.

Overview

The DeWalt DWMT86312OSP Mechanics 6 Point 3/8 Drive Socket 17 MM is a single metric hand socket made for turning 17 mm fasteners with a 3/8 inch drive ratchet or extension. This is a socket designed for mechanical fastening and removal. Model Number: DWMT86312OSP. If you need a common service size for automotive work, equipment repair, or general shop use, this socket covers that job without taking up extra space in your setup.

The 6-point socket design matters because it gives the tool more direct contact on the flats of the fastener compared to multi-point styles. In real use, that helps when you are breaking loose worn or tight bolts and want a more secure fit. For mechanics and serious DIY users, that is the difference between clean engagement and chewing up hardware that already looks rough.

DeWalt builds this socket from premium chrome vanadium steel, which is the right material for a piece that gets used over and over with hand tools. Strength and durability are the point here. A socket like this needs to hold its shape, resist wear, and stay dependable after repeated cycles on bolts, nuts, and threaded hardware in the garage or on the job.

One of the more practical details is the knurled beauty ring. That is not just there for looks. It gives you extra grip when your hands are greasy, when you are spinning the socket onto an extension by hand, or when you are fishing it out of a crowded tool box drawer. Small detail, useful payoff.

Because this is a 3/8 inch drive socket, it fits naturally into one of the most common ratchet and extension sizes used in automotive and general repair work. That makes it a good everyday shop piece instead of a specialty oddball. Pair it with your existing 3/8 inch drive setup and it drops right into regular service tasks.

This DeWalt metric socket makes the most sense for mechanics, maintenance techs, tradespeople who keep a service bag, and DIY users who want individual replacement sockets instead of buying another full set. If 17 mm is one of the sizes you reach for often, this is the kind of single socket that earns its place fast.

Secure Fit on Metric Fasteners

This 17 mm socket is built for straightforward mechanical work where clean fit matters. The 6-point opening gives solid engagement on the fastener, and the knurled ring adds control when you are handling the socket by hand.

Pro Tip

If you are replacing a missing socket in an existing set, match both the 17 mm size and the 3/8 inch drive before you order. That sounds obvious, but drive size mismatch is the reason a lot of single-socket purchases end up back in the drawer unused.
