GRENPRO Ratcheting Wrench Set, Combination Wrench Set, 22-Piece SAE & Metric and Standard, 72Th Long Open End, 1/4" to 3/4" & 6-18mm, Organizer With Roll Up Pouch, CR-V Socket Mechanic Hand Tools Sets

Why I kept reaching for this set

After a month of real, greasy, crawl-under-the-car use, the GRENPRO ratcheting wrench set has earned a permanent spot in my trunk and on my bench. I used it to tighten a battery terminal (10 mm), adjust a bicycle axle (15 mm), swap a mower deck pulley (1/2 in), and loosen a stubborn bracket in a cramped engine bay (13 mm). Nothing glamorous—just the kind of everyday jobs where a ratcheting combination wrench either helps or gets in your way. This one helped more often than not.

First impressions and build quality

Out of the pouch, the wrenches feel reassuring. They’re chrome vanadium steel with a full mirror polish and no sharp edges or grinding marks. The heads are cleanly machined and the box ends pick up the fastener with a positive bite. Each piece is clearly stamped with its size, and the markings stand up to shop grime and the occasional wipe with a solvent rag.

The overall pattern leans slightly longer than bargain-bin wrench sets, which translates into a touch more leverage without feeling unwieldy. The extra length is noticeable on mid-range sizes (12–15 mm, 1/2–9/16 in), where you’re more likely to be nudging fasteners that take real force.

Ratcheting mechanism and feel

The ratchet is a 72‑tooth design, so you get a 5° swing arc. In practice, that’s the difference between inching a bolt loose in a tight alternator bracket and taking the wrench off after every partial swing. The pawl engagement on my set is crisp with a predictable click, and backdrag (the resistance when you reverse direction) is moderate—light enough to turn small bolts without nudging the workpiece, but not so feathery that you mis-engage.

The head profile stays slim enough to get into spaces where a socket simply won’t fit. In the engine bay job I mentioned, the combination of the 5° arc and the low-profile head let me work between a wiring harness and a hose clamp without resorting to a stubby. That’s exactly why ratcheting combination wrenches exist.

Box-end geometry and rounding resistance

These are 12‑point “full-drive” box ends. You’ll appreciate that in two ways:

• They start easily on partially obscured fasteners, where a 6‑point can be fussy.
• They seem to load the fastener flats rather than the corners, so the wrench feels planted when you apply torque.

I didn’t round anything off during testing, including a slightly worn 13 mm bolt on the mower. Still, I’d avoid using ratcheting wrenches as your first attack on seized or corroded hardware. Break fasteners free with a 6‑point box or a breaker bar, then switch to these to speed through the rest.

The open-end side is a standard pattern with a slight lead-in chamfer. It’s fine for quick holds or when you need a second wrench to counter-torque, but the ratcheting box end is the star here.

Size coverage: what’s in, what’s missing

The kit provides 22 wrenches split across SAE and metric:

• Metric: 6, 8, 9, 10, 12, 13, 14, 15, 16, 17, 18 mm
• SAE: 1/4, 9/32, 5/16, 11/32, 3/8, 7/16, 1/2, 9/16, 5/8, 11/16, 3/4 in

This is a sensible selection for household, automotive, and small engine tasks. The 10, 12, 13, 14, and 15 mm sizes got the most use for me, along with 1/2 and 9/16 in. However, there are a few omissions to note:

• No 7 mm or 11 mm. Not deal-breakers, but they do come up on bicycles, appliances, and some European hardware.
• No 19 mm or 7/8 in. If you’re expecting to tackle larger suspension work or lug nuts with this set, you’ll want to supplement it.
• The top end stops at 18 mm and 3/4 in; that’s common at this price, but limits heavy automotive work.

If you regularly work on vehicles that use larger fasteners, plan on adding a 19 mm and 7/8 in ratcheting wrench or stepping up to a larger set.

In use: leverage, access, and control

The slightly longer handles make a difference where you need controlled force without jumping up to a breaker bar. I was able to break loose a medium-tight 15 mm bolt on a belt tensioner without drama. The mirror polish wipes clean easily and resists staining. In oily conditions, polished wrenches can be slippery; these kept enough grip thanks to their broader beam, though a light knurl patch would improve control.

One nice touch: the box-end edges are gently rounded, so you can bear down without digging into your palm. The head offset is mild, which helps with clearance next to flat surfaces while keeping the head low. It’s a good compromise for mixed tasks.

Organization: the roll-up pouch actually works

The Oxford cloth roll is better than the usual afterthought. The size of each pocket is printed, the slots are snug, and the flap keeps everything from sliding out when you carry it by the handle. It’s compact enough to stash in a trunk or side cabinet and tough enough to survive gravel and tailgate use. I prefer rails in the shop, but for a mobile kit the roll makes sense and speeds up the “find it, use it, stow it” loop.

Durability and long-term impressions

After a month, the polish shows the expected micro-scratches but no peeling or rust blooms. The ratchets haven’t developed play or dead spots. The size markings are still high-contrast and easy to spot. I didn’t encounter any deformed jaws or loose ratchet rings, even after leaning on the 18 mm more than I normally would.

Chrome vanadium isn’t exotic, but with proper heat-treatment it’s the right choice here. I wouldn’t hesitate to use these daily for light to medium duty. For regularly breaking free high-torque fasteners, I’d still reach for non-ratcheting 6‑points or a breaker setup.

What I’d change

• Add 7 mm, 11 mm, and 19 mm. That trio would shore up common gaps without bloating the kit.
• Offer a flex-head variant. The fixed head is sturdy and compact, but a flex option would unlock even more tight-space work.
• Reduce backdrag a hair on the smallest sizes. It’s already acceptable; lighter would be nicer for delicate fasteners.

None of these are deal-breakers, but they’d push the set from “very good” to “excellent.”

Who this set suits best

• Homeowners and DIYers who want one roll to cover most metric and SAE fasteners around the house, yard equipment, and the car.
• Hobby mechanics who need a compact, grab-and-go kit for road trips and quick repairs.
• Techs looking for a secondary set to keep in a service truck or loaner bag.

If you’re a full-time pro wrenching on heavy equipment or large suspension components, you’ll likely want a broader size range, flex heads, and maybe a 90‑tooth mechanism. This set can still be your travel backup.

Recommendation

I recommend the GRENPRO ratcheting wrench set. It hits the essentials: solid build, reliable 72‑tooth action, smart size spread for everyday tasks, and a pouch that actually keeps you organized. The slightly longer pattern provides useful leverage, and the machining inspires confidence on the fastener. Its limitations—missing a few sizes, fixed heads, and no coverage beyond 18 mm/3⁄4 in—are easy to plan around, especially at this price point.

If your work leans toward general mechanical, automotive maintenance, and household fixes, this set is an easy yes. Pair it with a 6‑point socket set for stubborn fasteners and add a couple of larger sizes as needed, and you’ll have a capable, compact kit that earns its keep.
