Key Features
Deep 3/4 Inch Reach This deep impact socket gives you the clearance needed for recessed fasteners and longer studs, while the 3/4 inch SAE size handles common larger hardware without stepping up to a bigger drive system. 6-Point Grip The 6-point design puts force on the flats of the fastener instead of the corners. That matters when you are working with stubborn nuts and bolts and want less chance of rounding them off. Better Hand Control A knurled control ring helps you grip the socket when your hands are oily or gloved, and the hard stamped markings stay readable longer than light surface markings.
Overview
The DeWalt DWMT73938OSP 6 Point 1/2 Inch Drive Deep Impact Socket 3/4 Inch SAE is a deep impact socket built for driving and removing 3/4 inch SAE fasteners with a 1/2 inch drive impact wrench or ratchet. This is a deep impact socket designed for fastening and loosening larger nuts and bolts in automotive, equipment, and general mechanical work. Model Number: DWMT73938OSP.
This socket uses a 6-point opening, which is the right call when you need solid engagement on high-torque fasteners. Instead of grabbing the corners, it puts more contact on the flats, which helps reduce rounding on worn or tight hardware. DeWalt also calls out DirectTorque technology, and the real benefit there is better fastener contact when you are leaning on an impact tool.
The deep well design matters anytime the fastener sits on a longer stud or down inside a recessed area. If you have ever tried to use a shallow socket where there is not enough clearance, you already know why a true deep impact socket earns its place in the drawer. The 1/2 inch drive size also makes sense here because it matches the kind of torque usually needed for 3/4 inch fasteners.
For day-to-day shop use, DeWalt adds a knurled control ring to improve grip while starting or removing the socket by hand. That sounds simple, but it is one of those details you appreciate when your gloves are dirty or your hands are slick. The chamfered open end also helps guide the socket onto the fastener faster, which saves a little time every time you reach for it.
The construction is listed as chrome vanadium steel with a black impact-style finish, and the socket uses hard stamped markings for long-term identification. That is important on a single socket like this because laser-etched or lightly printed markings tend to fade after repeated use. When a socket lives in a service cart, floor jack tray, or road box, clear markings help you grab the right size fast.
This DeWalt deep impact socket is best for mechanics, fleet maintenance techs, agricultural equipment service, trailer work, and serious DIY users who want a single 3/4 inch SAE impact socket instead of buying a full set just to cover one size. If you regularly work on suspension, lug-adjacent hardware, brackets, or machine fasteners that call for a 3/4 inch SAE socket, this is the kind of straightforward piece that does its job without drama.

Why the DeWalt DWMT73938OSP 6 Point 1/2 Inch Drive Deep Impact Socket 3/4 Inch SAE Earns Drawer Space
