Check Price on Amazon

Metric and SAE deep sockets in one case — the set a first impact wrench actually needs.

The hardest thing about buying your first impact set is guessing which sizes you will need, and this one removes the guess. You get 22 deep 6-point sockets covering both measurement systems: metric from 12mm through 24mm and SAE from 3/8” to 1”. It also drops in two extension bars at 3 inches and 5 inches plus a 1/2-to-1/4 adapter, so the case covers jumping from a stubborn suspension bolt to a small engine fastener in the same session. Everything is cut from drop-forged, heat-treated chrome vanadium steel wearing a black phosphate finish to hold rust back.

For a starter kit, the build punches above its class. It meets or exceeds ANSI performance standards and carries a 1-year quality warranty. Owners run it with a rattle wrench and report no complaints, with the case keeping everything organized so you are not digging for a 15mm in a pile of loose sockets. The size markings are etched and printed both, which survives grease.

Twenty-nine sockets and three extensions for the price of a decent wrench alone.

This is the set that surprises people who expected junk. It throws in 29 pieces — 10 SAE deep sockets from 3/8” to 1”, 15 metric deep sockets from 10mm to 24mm, and three extension bars at 3, 5, and 10 inches. That 10-inch bar is the one that matters most, because it lets you reach a bolt buried deep behind an engine mount without buying a separate accessory. It is forged from chrome vanadium steel with a black phosphate coating, and the 6-point design grips the flat sides of a fastener to keep corners intact.

The value story is the loudest thing here. This set carries the same 29 pieces as the SUNEX 5153DD further down, and it is the set that proves you do not need to overspend to get a complete range. It even out-plays the GEARWRENCH 84934N on extension length — that one offers three sizes in the box too, but this set goes all the way to a full 10 inches. Markings are laser-etched and stamped both, readable even under a dim hood.

There is one quirk worth knowing before you buy. The extension bars seat a little loose and can drop out of the socket easier than you would like, and that lone complaint is the only thing keeping this from being a clean sweep. For the price, most owners shrug it off. People run this on tire rotations, bumper swaps, and brake jobs and keep it in the trunk for emergencies, which is exactly the role it plays best.

Both deep and shallow sockets for every metric size from 8mm to 22mm.

Most sets force you to pick one profile, and this one refuses. It hands you both a deep and a shallow 6-point socket for each metric size from 8mm through 22mm — that is the whole 15-size run doubled up. Add a 5-inch and a 10-inch extension bar and a 1/2-inch universal joint (a pivoting elbow that lets you turn a bolt from an angle when a straight shot is blocked), and you can cover just about any fastener on a modern car without pulling a second tray out of the trunk.

It is built for torque. The heat-treated forged chrome vanadium steel is shaped to take the higher turning force an impact tool delivers, and the recessed 6-point design embeds the nut deeper so it stays put on a stubborn fastener instead of slipping off. The finish is black manganese phosphate, chosen over black oxide for stronger rust and corrosion resistance, and the sizes are laser-marked for quick reading in tight spaces.

The piece count stops where the price stops. This is metric-only and tops out at 22mm, so you will not find a 24mm socket to break an axle nut free. If your work is metric and the biggest thing you touch lives under 22mm, this set covers you two ways per size. If a big SAE project is on your list, look at the AMM set at number five instead.

Thirty-five deep sockets that run to 1-1/4″ and 24mm with nothing left out.

If you have ever hit a suspension rebuild and needed a socket the set did not have, this is the answer to that exact frustration. It packs 15 metric deep sockets from 10mm to 24mm and 14 SAE deep sockets from 3/8” all the way to 1-1/4”, plus three extension bars, a universal joint, and two adapters including a 3/8-to-1/2 piece. That contiguous SAE run is the standout: it steps up in sixteenths and stops at 1-1/4”, which is bigger than several sets above it that cap out at 1”.

The shop-floor reports back it up. It is forged from chrome vanadium steel, cold-headed and heat-treated, then given a black phosphate finish to fight rust. In use, people lean on it against real torque — it stripped stubborn lug nuts without round-off. The size markings are laser-etched onto every piece so you can read them at a glance, and the sockets live in a plastic toolbox.

Here is the trade-off to weigh. The carrying case comes in for mixed feedback — some find it well organized, others say it could be better. The upside is the case is the cheapest thing in the box to upgrade; the sockets themselves carry the value. If your work regularly reaches past an inch, this is the set that keeps going when the others quit.

A master set that walks into 32mm and 38 pieces of labeled storage to match.

For the person building out a shop box rather than patching a single repair, this is the one that steps past where most sets stop. It runs deep 6-point sockets across SAE from 3/8” to 1-1/4” and metric from 10mm all the way to 32mm — numbers that go beyond the 24mm ceiling of sets like the AMM at number five. The steel is drop-forged and heat-treated chrome vanadium (50BV30) with a black phosphate finish, and every socket carries both a high-visibility laser etch and a hard-stamped size label so identification never wears off.

The kit goes well past sockets alone. It ships with 3, 5, and 10-inch extensions, a 72-tooth quick-release ratchet handle (a fine-toothed mechanism that lets you re-grip with a smaller swing in tight spots), a universal joint, a 1/4-to-1/2 drill adapter, a 1/2-to-3/8 reducer, and a 3/8-to-1/2 three-way adapter. That adapter lineup is what lets the same case drive sockets off a power drill or a 1/2 impact wrench without extra shopping.

Two honest notes before you commit. The metric range includes 18mm, but buyers who need a specific missing size tend to flag it — check your vehicle’s fasteners against the list. And the included ratchet handle is the weak link: the one supplied unit is known to fail early on a hard job, though the brand replaced it. The sockets themselves are the durable part and keep working. If the ratchet is a bonus for you rather than the reason you buy, the value holds.

A deep 35-piece set built to shrug off daily shop abuse, box and all.

Working technicians need a set that will not fold under a stubborn bolt on a Monday morning, and this one is put together for that. All 35 pieces are deep sockets — 14 SAE from 3/8” to 1-1/4” and 16 metric from 8mm to 24mm — cut from heat-treated forged chrome vanadium steel that is made to carry the higher torque a heavy impact tool produces. The 6-point lateral drive presses on the flat sides of a hex fastener, which is exactly what keeps a soft bolt head from rounding off.

The case is the detail that separates it from cheaper kits. It is blow-molded with a double-lock closure — two latches instead of one — holding a firm grip that keeps the sockets from tumbling out on the way to a job. The black manganese phosphate finish resists corrosion better than plain black oxide, and every size carries both a laser mark and a hard stamp. Sockets ship lightly oiled with an anti-rust coat, which is normal and wipes off.

The recurring gripe is the case again: a few owners find the molded slots do not grab the sockets tightly enough and prefer to line it themselves. The sockets themselves are the reason people stay — this set gets described as one of the best impact sets a person has owned, and it handles heavy automotive and lawnmower repairs without stressing. New technicians and seasoned hands both land here comfortably.

The shallow-barrel twin of the top pick, for fasteners a deep socket cannot reach.

There is a reason this set sits next to the deep version on this list rather than replacing it: some fasteners live where a shorter socket is the only thing that fits. This is the same 19-piece SAE run as the top pick — 3/8” through 1-1/2” in every sixteenth, no skips — but in a standard-height barrel instead of a deep one. It uses chrome molybdenum steel with the same off-corner loading design that presses on bolt flats to hold off rounding, and the same black oxide finish against corrosion. At 3.3 pounds it is a touch lighter than its deep-profile sibling, and it rides in the same style of latched case.

Longevity is where this set earns its keep. Millwrights and professional mechanics report years of use without cracking or softening, including one running it a few times a week for four years. The consistency is the draw: no skipped sizes, a surface-drive design that keeps bolts from rounding, and a case with metal latches built to take field knocks. If you already own the deep version, this one slots in beside it and covers the jobs the deep sockets cannot reach.

The one point of friction is finish consistency — a single-size socket here and there has arrived with a slightly different finish from the rest. It fits in spec and works fine, just not perfectly matched to the set. Treat it as a cosmetic quirk, not a functional one.

Double-deep sockets that reach clear over long studs, in a premium chrome-moly build.

This is the specialist of the group, and it earns a place when standard deep sockets come up short. Every socket is double-deep — an extra-long barrel made for accessing fasteners sitting on long threaded studs where an ordinary socket bottoms out before it bites. The 29-piece set covers SAE 7/16” to 1-1/4” and metric 10mm to 27mm, plus two bonus flip sockets that let you quickly reach the two common lug nut sizes without swapping pieces. The steel is Cr-Mo (chrome molybdenum), chosen for the strength and flexibility to handle high-torque impact tools.

Build quality is what owners notice most. The radius corner design places force on the walls of a fastener rather than its corners, cutting wear and holding torque, and the chamfered opening lines a nut up and helps it seat quickly. Dual size markings — laser-etched and roll-stamped both — keep every socket identifiable for good. At 18 pounds for the set, it is a substantial case holding an all-deep array that includes a full SAE/Metric run.

The one thing to plan around is missing metric sizes. The metric range skips 20mm, 23mm, and 24mm, and 24mm in particular is a socket many cars actually need — you would have to buy it separately. If your vehicle can throw a 24mm nut at you, factor that in. For everyone else, this double-deep set delivers premium reach and Cr-Mo toughness in one box, and the included flip sockets speed up tire work nicely.
