Description

Key Features

1/2 Inch Drive Fit

Built for 1/2 inch drive impact tools, so it matches the setup most techs and serious DIYers already use for heavier fasteners.

Deep Socket Reach

The deep well design gives you the extra clearance needed for long studs and recessed nuts where a shallow socket comes up short.

Grip and Durability

Chrome vanadium steel adds strength, and the knurled beauty ring helps reduce hand slippage when you are swapping sockets fast.

Overview

The DeWalt DWMT73937OSP 1/2 Drive x 11/16 6 Point Deep Impact Socket is a single SAE deep impact socket for mechanics, installers, and anyone working with stubborn fasteners using a 1/2 inch drive setup. This is a deep impact socket designed for driving and removing 11/16 inch fasteners with impact-rated tools. Model Number: DWMT73937OSP.

The spec that matters first is the combination of a 1/2 inch drive, 11/16 inch socket size, and 6 point opening. That setup gives you a solid fit on the flats of the fastener, which is what you want when torque goes up and you are trying to avoid rounding worn hardware. If you use impact wrenches for automotive work, equipment service, trailer maintenance, or general shop work, this is the right kind of socket design for repeated high-torque fastening.

The deep well body is the practical advantage here. It gives you room to work over longer bolts and exposed studs that would bottom out in a standard shallow socket. That makes a real difference on suspension hardware, lug-adjacent service points, brackets, and other assemblies where thread length gets in the way of a normal socket.

DeWalt builds this socket from chrome vanadium steel for strength and durability, and that matters because impact sockets take repeated shock loads instead of smooth hand-tool force. The knurled beauty rings are a small feature, but a useful one. When your hands are oily, gloved, or moving quickly between sockets, that added grip helps with faster changes and less fumbling at the cart or under the hood.

This is a simple tool, but the details are right for real work. The black impact finish and clear size marking help it fit in with a dedicated impact set, and the 6 point geometry is the smart choice for users who care more about secure engagement than all-purpose fit. For a socket like this, reliability matters more than gimmicks.

If you already run a 1/2 inch drive impact wrench, breaker bar, or ratchet and need an SAE deep socket in 11/16 inch, this DeWalt deep impact socket is an easy add to the drawer. It is best for mechanics, maintenance techs, farm and fleet users, and serious DIYers building out a dependable impact socket lineup one size at a time.

Reach Longer Studs and Recessed Fasteners

A deep socket earns its keep when standard sockets cannot clear the threads. This one is made for exactly that kind of work, giving you the reach needed without stepping up to an awkward adapter setup.

• 11/16 inch SAE socket size for matching fasteners
• Deep well construction for long bolts and studded connections

Built for Impact Tool Use

The 6 point design is the right call when you are leaning on torque. It grips the flats of the fastener more securely than a multi-point design, which helps when hardware is tight, dirty, or a little beat up.

• 6 point socket opening for solid fastener engagement
• Chrome vanadium steel body for strength and durability
