Key Features
Deep Reach The deep socket body gives you clearance on nuts sitting over longer studs, so you can stay with one socket instead of fighting a shallow one that will not seat fully. 6-Point Grip The 6-point opening is built to grab the flats of the fastener more securely, which helps reduce rounding when you are putting real torque through an impact setup. Built for Impact This DEWALT deep impact socket uses chrome vanadium steel and a grip-focused ring design to hold up to repeated shop and garage use while staying easier to handle with oily or gloved hands.
Overview
The DEWALT DWMT73942OSP 6 Point 1/2 in. Drive Deep Impact Socket 1 in. SAE is a single deep impact socket built for turning 1 inch SAE fasteners with a 1/2 inch drive impact wrench or ratchet setup. This is a deep impact socket designed for high-torque fastening and removal of larger SAE nuts and bolts. Model Number: DWMT73942OSP.
What matters here is the combination of a 1/2 inch drive, a deep well body, and a 6-point opening. The 1/2 inch drive size makes it a practical fit for common shop and garage impact tools, while the deep profile gives you the reach needed when a nut sits down over a protruding stud. That is the difference between getting fully seated on the fastener and chewing up the corners because the socket cannot engage deep enough.
The 6-point design is the right call for impact work because it grabs the flats of the fastener more directly than a multi-point socket. DEWALT also calls out DirectTorque technology, which is there for the same reason: help reduce rounding and keep a better hold on stubborn hardware. If you are breaking loose rusted, over-tightened, or repeatedly serviced fasteners, that kind of grip matters.
DEWALT lists chrome vanadium steel construction for strength and durability, along with hard stamped markings for easier size identification over time. That sounds simple, but it matters once the socket has been tossed in a box, covered in grime, or used long enough that painted markings would normally disappear. The knurled control ring is another practical touch because it gives you a little more purchase when swapping sockets by hand.
This is not a general chrome hand socket pretending to be impact rated. It is an impact socket, and the black oxide style finish and retaining pin hole are exactly what you want to see on a socket meant for impact duty. It is made for real torque, not just light bench work.
Compatibility is straightforward: this socket is sized for 1/2 inch square drive tools and accessories, and it is intended for 1 inch SAE fasteners. That makes it a good fit for mechanics, equipment maintenance, trailer work, agricultural service, and general repair where larger standard-size hardware is still common.
If you need one specific deep socket instead of a whole set, this is a smart buy. The DEWALT DWMT73942OSP 6 Point 1/2 in. Drive Deep Impact Socket 1 in. SAE makes sense for users who already have a 1/2 inch impact platform and want a dedicated socket that reaches deeper, grips better, and holds up to repeated high-torque use.
DEWALT DWMT73942OSP Deep Impact Socket for Stud Clearance

- Deep socket profile for better access on extended studs and recessed nuts
- 6-point opening helps reduce fastener rounding under heavy load
- Hard stamped markings are easier to read after repeated use
