DeWalt Mechanics Tool Set (173 pc)

A trunk-friendly mechanics set that pulls its weight

I keep a comprehensive mechanics kit in my trunk for roadside fixes and weekend projects, and over the last few months this 173-piece DeWalt set has been the one I reach for most. It’s not the flashiest or the most exotic ensemble, but it’s thoughtfully curated and covers a wide spread of tasks with fewer compromises than I expected at this price and size. If you want a no-drama, grab-and-go setup with credible tools and sensible organization, this one makes a strong case.

What you get and how it’s organized

The kit spans 1/4-, 3/8-, and 1/2-inch drives, with a pear-head ratchet for each. You get a broad run of 6-point sockets in both SAE and metric, standard and deep, supported by extensions, a bit adapter with common driver bits, a spinner handle for low-torque jobs, a spark plug socket, nut driver bits, and a selection of combination wrenches and hex keys. It’s housed in a molded plastic case that, importantly, actually keeps things in place. I’ve tossed it onto gravel and slid it across a tailgate; the sockets stayed put and the latches didn’t pop.

The sizing coverage hits the usual automotive and general-mechanic fasteners I see most often. It’s not a specialty kit—no impact sockets, no E-Torx or deep specialty bit sockets—but for routine maintenance, small engine work, light plumbing, and electrical hardware, it’s well-balanced.

Ratchets and sockets: the heart of the set

The ratchets are 72-tooth designs, which equates to an arc swing of about 5 degrees. In practice, that’s the difference between getting something done in a cramped engine bay and having to pull a component to get room. The mechanisms are positive, with minimal back drag out of the box, and pawl engagement feels consistent. They’re not as ultra-fine as premium 90- or 120-tooth units you’ll find in high-end truck brands, but the 72-tooth profile is a sweet spot: robust enough to inspire confidence and fine enough to work behind a radiator or under a sink.

The 6-point sockets have DeWalt’s DirectTorque geometry, which shifts load from the corners to the flats. On stubborn, slightly corroded fasteners, I could lean into them without that queasy sense that I was about to round a head. I put particular stress on the 10 mm, 13 mm, and 1/2-inch sizes (because of course), and they held up without visible distortion or slop. Engagement feels snug, not oversize, and the detents align cleanly with the anvil balls on the ratchets.

Finish and ergonomics

Everything carries a full-polish chrome finish for corrosion resistance. I left a few sockets and a wrench out in a wet organizer overnight (whoops), and they wiped clean with no spotting. Chrome can be slippery, but the knurled rings on the sockets are genuinely helpful for finger-spinning hardware. The ratchet handles have a gentle palm swell without rubber overmold—comfortable enough for extended use and easy to wipe clean.

Size markings are large and easy to read—something I appreciate more as the light fades in a garage. The combination wrenches are standard pattern with open and box ends. They’re not ultrathin “tappet” profile wrenches, but they fit nicely on common fasteners and didn’t cam off under load.

In the field: where it shines

• Automotive: I used the 3/8-inch drive with a 6-inch extension and a deep 16 mm socket to swap an alternator on a compact sedan. The 5-degree arc swing saved time around the tensioner. The spark plug socket did its job on a small engine service; the rubber insert held plugs securely without sticking on extraction.

• Mechanical/electrical: The 1/4-inch drive and bit adapter were perfect for access panels and terminal blocks. The spinner handle makes quick work of low-torque fasteners, and the hex keys—while basic—covered the set screws and appliance panels I encountered.

• Plumbing/pipefitting: Chrome sockets aren’t for pipe dope and impact guns, but with an extension and a deep socket I was able to snug supply line nuts in a tight vanity. The corrosion-resistant finish is easy to clean after pasty sealants.

The overarching theme: this set moves between tasks without leaving me hunting for another box. For most roadside jobs and around-the-house repairs, I didn’t feel under-equipped.

Case and portability

The case is compact enough to slide under a truck seat or sit against a garage wall. The molded trays line up with the socket sizes intuitively, which means putting things back is quick (and you can spot what’s missing at a glance). The latches are positive. I wouldn’t treat the case like a step stool, but it’s held up to regular transport in a cargo area without warping. For a kit you’ll store in a vehicle, that matters.

Where it comes up short

• Ratchet refinement: The 72-tooth action is solid, but if you’re accustomed to ultra-fine 90+ tooth ratchets for precision inside dashboards or HVAC cabinets, you’ll notice the difference. Not a deal-breaker, but worth noting.

• Wrench depth: The included combination wrenches cover common sizes, but this isn’t a comprehensive wrench set. If you rely heavily on wrenches for automotive or plumbing work, you’ll likely supplement with flex-head or ratcheting styles.

• Bits and drivers: The included bit kit covers everyday Phillips, slotted, hex, and Torx, but it’s not a hardened, impact-rated assortment. Heavy use in decking screws or lag bolts isn’t what this set is for.

• No impact or specialty sockets: This is a hand-tool set. If you routinely use an impact wrench or need specialty fastener profiles (E-Torx, spline, etc.), you’ll need add-ons.

None of these are surprises given the purpose and price point, but they’re worth calling out so you match expectations to your workflow.

Durability and standards

DeWalt states the tools meet or exceed ASME specifications, and based on my use, tolerances and hardness seem appropriate. I deliberately torqued several fasteners near spec with a separate torque wrench after initial snugging with these ratchets, and there was no perceptible play introduced. The chrome has resisted the usual mix of grease, salt spray, and the occasional drop onto concrete. There’s also a full lifetime warranty (region dependent). I haven’t had to exercise it, but that safety net matters for a set intended to live in a vehicle or job box.

Value and who it’s for

As an all-in-one mechanics kit, this 173-piece set strikes a practical balance: wide coverage, credible ratchets, sensible organization, and corrosion-resistant finish. It’s ideal for:

• DIYers who want one case that solves most household, automotive, and small-engine tasks.
• Mobile techs and tradespeople who need a trunk or van kit that won’t scatter parts when it’s tossed around.
• Apartment dwellers or students who need capability without building a toolbox piece by piece.

If you’re a professional mechanic with specific demands—impact-rated sockets, specialty profiles, ultra-fine ratchets, or a full drawer of wrenches—this won’t replace your main box. But as a secondary kit, it’s compelling.

Recommendation

I recommend this DeWalt set for anyone seeking a reliable, portable mechanics kit that covers the basics and then some without drama. The 72-tooth ratchets offer genuinely useful access in tight spaces, the 6-point sockets with DirectTorque geometry grip fasteners confidently, and the case organization makes it easy to keep track of tools in the field. Add the corrosion-resistant finish and lifetime warranty, and you have a set that’s easy to live with and hard to fault for general-purpose work. Pair it with a few specialty items tailored to your trade—impact sockets, a more complete wrench set, and a torque wrench—and you’ll be equipped for a wide range of jobs with minimal hassle.
