Key Features

Deep Reach

The deep socket design gives you the clearance you need on long bolts and threaded studs, so you can get full engagement where a standard socket comes up short.

Built for Impact Use

Heat-treated steel construction is made for impact-duty work. That matters when you are leaning on stubborn fasteners and need a socket that holds up.

6-Point Grip

This DEWALT deep impact socket uses a 6-point opening that grabs the flats of the fastener more securely, helping reduce rounding compared to looser-fitting designs.

Overview

The DEWALT DWMT74658OSP 6 Point 1/2″ Drive Deep Impact Socket 1-1/4″ SAE is a single deep impact socket built for heavy-duty fastening and removal work. This is a deep impact socket designed for driving and removing large SAE fasteners with a 1/2 inch drive impact wrench or ratchet. Model Number: DWMT74658OSP. If you need a socket for larger nuts and bolts and you want the extra depth for long studs, this is the right style of socket to keep in the drawer.

The key setup here is straightforward and useful: a 1-1/4 inch SAE socket size, a 1/2 inch drive, and a deep profile. That combination makes it a practical fit for mechanics, equipment service, trailer work, and general shop fastening where larger hardware is common. The 6-point design matters because it contacts the flats of the fastener more directly, which helps the socket stay planted under load and reduces the chance of rounding corners on tight or worn hardware.

DEWALT also calls out DirectTorque technology, which is aimed at helping prevent fastener rounding. On the job, that matters most when you are working with rusty suspension hardware, overtorqued lug-related fasteners, or equipment bolts that do not want to move. A good impact socket is not about flash. It is about fit, durability, and staying usable after repeated impact cycles, and that is exactly where this socket is positioned.

For durability, source data lists heat-treated CR-440 steel and an oil-rubbed black oxide coating. The steel gives the socket the strength expected for impact-duty use, while the black oxide finish helps resist corrosion in shop and jobsite conditions. DEWALT also notes laser-etched markings, which are easier to read on a dark impact socket than shallow stamped markings once the tool starts seeing oil, grime, and regular use.

There is also a practical safety detail here: the socket is O-ring and retaining pin compatible. If you are using this on an impact wrench in tougher service conditions, that extra retention matters. It helps keep the socket secured to the anvil during repeated impacts, especially when you are working overhead, around machinery, or moving quickly through repetitive fastening tasks.

This DEWALT socket is best for users who already know exactly what size they need and want a dependable SAE impact socket rather than a full set. It makes the most sense for mechanics, service techs, and serious DIY users who need a 1/2 inch drive deep socket for occasional or regular work on larger fasteners. If your work involves long studs, impact tools, and hardware that needs real torque, a dedicated deep socket like this is the right move.

Made for Larger Fasteners and Long Studs

This deep impact socket is the kind of piece you buy for a specific job and keep for years. The extra depth gives you room to work over protruding threads, and the impact-rated build is meant for repeated high-torque use.
