GearWrench Reversible Ratcheting Wrench Set: Which Sizes and Set Should You Buy?
The right GearWrench reversible ratcheting wrench set depends on which fasteners you encounter: choose a metric set for metric hardware, an SAE set for inch-sized hardware, or a combination set if you work across both. The reversible ratcheting box end changes direction with a small flush-mounted lever, while its 15-degree offset helps keep your hand clear of nearby surfaces. Before buying, check the exact size list: GearWrench sells multiple configurations, and the included sizes are not identical across every set.
How the reversing lever and box end work
On reversible models, a compact lever sits flush in the ratcheting box end. Move it to switch between tightening and loosening without taking the wrench off the fastener. Because the lever does not project far from the wrench, it is less likely to snag than a prominent switch—useful when access around a fastener is tight. The trade-off is that the lever can be harder to operate with gloves or oily fingers, and the available clearance still depends on the surrounding parts.

The box end is offset 15 degrees from the wrench handle. That angle can give knuckles room over a flat surface and lets you reposition the wrench between strokes in confined spaces. It does not make every fastener accessible: the head still needs enough room to fit around the nut or bolt, and a nearby obstruction can prevent a full ratcheting swing.
GearWrench reversible ratcheting models commonly use a 72-tooth ratcheting mechanism, equivalent to a 5-degree swing between engagement positions. That fine increment can help where a conventional wrench cannot move through a broad arc. Confirm the tooth count on the exact model, because specifications can vary by product line and set.
Common set sizes at a glance
The table compares familiar GearWrench set configurations, but it is not a guarantee that every current package contains those sizes. Package contents can vary by model number, market, and product revision. Check the manufacturer’s size list before ordering, especially if you need one particular wrench.
| Set type | Common size range | Typical size count | Best fit |
|---|---|---|---|
| SAE, 8-piece | 5/16–3/4 in. | 8 | Common inch-sized hardware in older vehicles, equipment, and home repairs |
| Metric, 8-piece | 8–19 mm | 8 | Common metric fasteners where a compact selection is enough |
| SAE, 12-piece | 1/4–1 in. | 12 | Broader coverage for inch-sized fasteners |
| Metric, 12-piece | 8–19 mm, with intermediate sizes included | 12 | More metric coverage than a basic set, including sizes that may be skipped in an 8-piece set |
| Combination set | Varies by package; often spans common SAE and metric sizes | Varies | Mixed hardware or a shared household tool kit |
“8–19 mm” alone does not tell you whether a set includes every size in that range. For example, a smaller set may include 8, 10, 12, 13, 14, 15, 17, and 19 mm, while a larger one may fill in additional sizes. Likewise, an SAE range is not the same as a complete size-by-size run. Match the listed contents to your actual fasteners rather than buying by the endpoints.
What the spline-drive box end grips
The box end’s spline-drive geometry is designed to contact fasteners at multiple points. It can grip common hex-head bolts and nuts, including some rounded or damaged fasteners, and can be useful on 12-point fasteners as well as standard six-point hardware. That versatility is helpful when the fastener’s condition or shape is less than ideal.
It is not a guarantee against rounding. A spline wrench can still slip if the size is wrong, the fastener is badly damaged, the wrench is not fully seated, or the connection is heavily loaded. It should not be treated as a substitute for a dedicated tool on every fastener: use a correctly sized six-point socket for a stubborn, high-torque six-point fastener when practical, and use a flare-nut wrench for delicate tubing fittings. Avoid applying a cheater bar or impact tool unless the wrench is specifically rated for that use.
Choose by the work you actually do
| Your situation | Practical choice | Why |
|---|---|---|
| Mostly one system of fasteners | SAE-only or metric-only set | You avoid paying for sizes you rarely use and can focus on filling gaps in your existing tools. |
| Household jobs with mixed hardware | Combination set | It covers both measurement systems, provided its individual size list matches the hardware you encounter. |
| Occasional repairs and limited storage | Smaller set with the most-used sizes | A compact selection is easier to store; add individual wrenches if a recurring job requires a missing size. |
| Frequent automotive or equipment maintenance | Larger set, selected for the vehicle or equipment | More sizes reduce interruptions, but check access and fastener specifications before assuming the set covers the job. |
| Rusty or already rounded fasteners | Use the spline wrench cautiously; keep a six-point socket or extractor available | Spline contact may help on imperfect fasteners, but severe damage may require a dedicated removal tool. |
A simple coverage check helps avoid buying duplicates: list the fastener sizes you use most, then compare that list with the package contents and your current tools. If a combination set costs more than a single-system set, its extra value is the number of useful sizes you do not already own—not simply the total number of pieces. General market prices vary by configuration and retailer, so compare the exact model and included sizes rather than relying on a price-per-piece figure alone.
Ownership details that affect long-term usefulness
The ratcheting head has more moving parts than a fixed box wrench, so grit, metal shavings, and dried oil can interfere with smooth operation. Wipe the wrench after use, keep the mechanism free of packed debris, and follow the manufacturer’s care guidance if it needs cleaning or lubrication. Do not force a sticky reversing lever; remove dirt first and make sure the direction selector is fully engaged before turning a fastener.
As with any ratcheting wrench, repeated overload can damage the mechanism before the wrench shows obvious external wear. If the ratchet skips under normal hand pressure, the lever will not stay in position, or the head feels rough after cleaning, stop using it for demanding work and consult the manufacturer about service or replacement. For breakaway torque on a stuck fastener, use a suitable non-ratcheting tool first, then switch to the ratcheting wrench for quicker turning once the fastener moves.
For woodworking, this set is most useful around machinery, shop fixtures, benches, and assembly hardware that use nuts and bolts. It is less suitable for driving screws or tightening fasteners that call for a torque-controlled method. The best purchase is the smallest set that covers your real fastener sizes—with the correct measurement system and enough clearance for the wrench head and handle to work.
