Key Features
Direct Torque Grip DirectTorque technology is built to help reduce fastener rounding. That matters when you are leaning on stuck hardware and do not want the socket slipping off the flats. Deep Impact Socket This DeWalt deep impact socket gives you the reach needed for longer studs and recessed fasteners. The 17 mm size and 1/2 inch drive make it a practical fit for heavier-duty fastening work. Better Hand Control A knurled control ring helps you hold and position the socket with greasy or gloved hands. Hard stamped markings also stay readable longer than painted size labels.
Overview
The DeWalt DWMT73949OSP 6 Point 1/2 in. Drive Deep Impact Socket 17 mm is a single deep impact socket built for driving and removing 17 mm fasteners with impact tools and hand tools that use a 1/2 inch drive. This is an impact socket designed for fastening and loosening hex fasteners in mechanical, construction, and industrial work. Model Number: DWMT73949OSP.
This socket uses a 6-point opening, which is the right call when you want better contact on the flats of a nut or bolt head instead of loading the corners. DeWalt also calls out DirectTorque technology, which is there for one reason that matters on the job: it helps reduce the chance of rounding worn or tight fasteners when you are putting real force through the tool.
The deep socket design gives you extra reach where a standard socket comes up short. If you are working on hardware with exposed threads, deeper studs, or recessed fasteners, that added depth keeps the socket useful instead of forcing you to switch setups. For mechanics and techs, that means fewer interruptions when moving from one fastener style to the next.
Build-wise, DeWalt lists chrome vanadium steel construction for strength and durability. The socket also features a brushed finish and hard stamped markings, so the size identification is less likely to disappear over time. That is a small detail until you are digging through a drawer or socket rail trying to find the right size fast.
Another practical touch is the knurled control ring. That added texture gives you a better grip when starting the socket by hand, pulling it from a toolbox, or swapping between fasteners with gloves on. DeWalt also notes a beveled opening to help guide the socket onto the fastener more easily, which saves a little time every time you use it.
If you need a 17 mm impact socket for repeated service work, equipment maintenance, shop use, or general fastening with a 1/2 inch drive setup, this is a straightforward choice. It is best for users who want a durable single-size deep socket instead of a full set, and it makes the most sense for anyone replacing a lost 17 mm socket or building out a more dependable impact socket lineup one size at a time.
Built to Handle Tight 17 mm Fasteners
