Key Features

Deep 18 mm Reach

This DeWalt DWMT94955OSP deep socket gives you the extra reach you need on recessed fasteners where a standard socket comes up short.

Chrome Vanadium Build

Made from premium chrome vanadium steel for the strength and durability a mechanic’s socket needs when it sees regular shop use.

Better Grip By Hand

Knurled beauty rings help reduce hand slippage, which makes it easier to start or remove the socket when your hands are oily or you’re working quickly.

Overview

The DeWalt DWMT94955OSP Mechanics 6 Point 3/8 in. Drive Deep Socket 18 mm is a single deep socket built for mechanics, technicians, and anyone working with 18 mm fasteners. This is a deep socket designed for fastening and removal on recessed nuts and bolts. Model Number: DWMT94955OSP.

The key detail here is the combination of an 18 mm size, a 6-point opening, and a 3/8 in. drive. That makes it a practical choice for users who want solid engagement on hex fasteners without stepping up to a larger drive size than the job calls for. A deep socket also gives you more clearance over longer studs and fasteners set below the surface.

DeWalt builds this socket from premium chrome vanadium steel, which matters because a socket takes repeated load through the drive end and the fastener contact points. Good material helps it hold up to regular shop work, box maintenance, and general mechanical service without feeling like a throwaway piece.

The knurled beauty rings are a simple feature, but they are useful in real work. When you are swapping sockets by hand, especially with greasy fingers or while moving between fasteners, the textured ring gives you a little more control. That saves fumbling and makes the socket easier to handle off the ratchet or extension.

This DeWalt deep socket is a good fit for automotive work, equipment maintenance, and general repair where 18 mm hardware shows up and extra socket depth helps. If you already run a 3/8 in. ratchet and need a dedicated 18 mm deep socket instead of digging through a mixed set, this is the straightforward piece to add to the drawer.

Reach Recessed Fasteners More Easily

A deep socket earns its keep when standard depth is not enough. This one gives you the extra internal depth needed for longer studs and hardware set below the surface.

• 18 mm socket size for matching metric hex fasteners
• Deep socket format for added clearance on extended threads and recessed hardware
• 3/8 in. drive works well for common ratchet and extension setups

Pro Tip

If you are working on a stud with limited clearance, pair a deep 18 mm socket like this with a 3/8 in. extension instead of jumping to a larger drive tool. You keep better access while still clearing the extra thread length.
