An adjustable wrench won't replace a proper set of combination wrenches, but it covers the jobs they can't: odd-size nuts, plumbing fittings, a backup wrench to hold a bolt head, and the one fastener you don't have the right size for. A good adjustable wrench set gives you two or three lengths so you're covered from small hardware to large fittings.
What separates a good adjustable wrench from a frustrating one is how well it holds its setting. A sloppy jaw or a thumbscrew that creeps open is how fasteners get rounded. After that, look at jaw capacity (how wide it opens), head thickness, and whether the handle is comfortable for longer jobs.
We compared current adjustable wrench sets from Crescent, GearWrench, Milwaukee and Craftsman using their published specs.

The Best Adjustable Wrench Sets, Reviewed
1. Crescent AC3PC 3-Piece Set: Best Overall
Who it's for: homeowners, DIYers and mechanics who want one reliable set in the three most useful sizes.
The AC3PC is the set people picture when they say "crescent wrench set." You get a 6-inch, 8-inch and 10-inch wrench with jaw capacities of 15/16" (24 mm), 1-1/8" (29 mm) and 1-5/16" (34 mm). Crescent lists a hex jaw design to reduce slippage, a tension spring to stabilize the jaw, and a larger knurl for easier adjustment and a tighter fit.
Each wrench has laser-etched SAE and metric scales, so you can pre-set the jaw before reaching into a tight spot. The heat-treated forged alloy steel has a satin chrome finish with a polished head. The set weighs 2.2 lb, comes carded, and is covered by Crescent's full lifetime warranty.
Pros
- Three most useful sizes
- SAE and metric scales on the jaw
- Full lifetime warranty
Cons
- No storage pouch
- 10-inch capacity is smaller than GearWrench's and Milwaukee's

2. Crescent AC26810CV Cushion Grip Set: Best Comfort Grip
Who it's for: anyone who uses adjustable wrenches for long stretches, such as plumbing or assembly work.
This is the AC3PC's comfort version. Sizes and capacities are the same (6", 8" and 10" with 15/16", 1-1/8" and 1-5/16" jaw capacities), and so are the hex jaw design, tension spring, larger knurl and laser-etched SAE and metric scales.
The difference is the molded rubber cushion grip on each handle, which Crescent says improves comfort and reduces hand fatigue. The set ships boxed with a storage pouch and weighs 2.45 lb. Crescent backs it with its full lifetime warranty.
Pros
- Cushion grips for comfort
- Storage pouch included
- Same jaw features as the AC3PC
Cons
- Grips add a little bulk in tight spots
- Same 1-5/16" limit on the 10-inch

3. GearWrench 89750 2-Piece Set: Best for Mechanics
Who it's for: mechanics who use an adjustable wrench to hold or turn larger fasteners and want it to bite like a fixed wrench.
GearWrench built the 89750 around automotive use. Its off-corner loading concentrates force on the flats of the fastener instead of the corners, the same idea used in quality sockets and combination wrenches, to help prevent rounding under heavy torque. The large knurled adjustment screw is designed to resist jaw backoff in high-force use.
The capacities are the largest here for their lengths: 1-3/16" (30 mm) for the 8-inch and 1-7/16" (37 mm) for the 10-inch. GearWrench says the jaws are about 20% wider and the head slim for tight spaces. The set is heat-treated steel in satin chrome, weighs 1.85 lb, and carries a full lifetime warranty. It comes in blister packaging without a storage case.
Pros
- Off-corner loading reduces rounding
- Largest jaw capacities for 8" and 10"
- Slim head
Cons
- No 6-inch wrench
- No storage case

4. Milwaukee 48-22-7400 2-Piece Set: Best Wide-Jaw 10"
Who it's for: tradespeople and DIYers who want a short wrench for small hardware and a 10-inch that opens wide.
Milwaukee's set pairs a 6-inch wrench with 15/16" capacity and a 10-inch with 1-3/8" capacity. Its main selling point is the proprietary adjustment screw, which Milwaukee says keeps the jaws from backing off. The jaws are parallel, which Milwaukee says won't slip or damage finished surfaces.
A laser-etched ruler helps you set the size, the handle is shaped not to dig into your palm, and a tether-ready loop on the handle matters if you work at height. The wrenches are chrome-plated steel with a red handle grip. Milwaukee covers its adjustable wrenches with a Limited Lifetime Warranty, not the Lifetime Guarantee on its sockets and ratchets.
Pros
- Anti-backoff adjustment screw
- 1-3/8" capacity on the 10-inch
- Tether-ready handles
Cons
- No 8-inch wrench
- Limited lifetime warranty

5. Craftsman CMMT12001 3-Piece Set: Best Budget
Who it's for: homeowners who want a basic 6, 8 and 10 inch adjustable wrench set with a strong warranty.
Craftsman's three-piece set includes all-steel 6-inch, 8-inch and 10-inch adjustable wrenches with wide-opening jaws, large size markings and a full-polish chrome finish for corrosion resistance. Craftsman backs it with a full lifetime warranty.
Craftsman doesn't publish jaw capacities for each wrench on its product page, so if you need a specific maximum opening, check the packaging or listing photos. Its product pages also describe the measurement system inconsistently (SAE only on one page, SAE and metric on another), so don't count on a metric scale.
Pros
- Three sizes at a budget price
- All-steel construction
- Full lifetime warranty
Cons
- Jaw capacities not published
- Metric scale not confirmed
CRAFTSMAN Standard (SAE) Adjustable Combination Wrench Set (3-Piece) CMMT12001
by CRAFTSMAN
6. GearWrench GWPTAW8 11-Piece Pass-Thru Set: Most Versatile
Who it's for: anyone who wants a compact kit that handles adjustable-wrench work and socket work.
The GWPTAW8 pairs an 8-inch adjustable wrench with a reversible 3/8-inch Pass-Thru ratchet and Pass-Thru sockets. The wrench opens to 1-1/8" and has a reversible serrated jaw for pipe up to 1", plus an SAE and metric laser-etched scale. That means it can act as a small pipe wrench as well as a regular adjustable.
The Pass-Thru sockets run on the included ratchet. GearWrench says they fit hex, square, 12-point, E-Torx, partially rounded hex and spline fasteners, and that each works as both a standard and a deep socket. The kit stores on a socket rail and weighs 1.8 lb. GearWrench lists no warranty on the full set, only on individual items. Crescent sells a similar kit as the CPTAW8. For more on the system, see our pass-through socket set guide.
Pros
- Adjustable, pipe and socket work in one kit
- Sockets fit six fastener types
- Compact rail storage
Cons
- Only one wrench size
- No warranty on the set as a whole

Adjustable Wrench Set Buying Guide
Sizes: Why 6, 8 and 10 Inches
Wrench length sets both reach and jaw capacity. A 6-inch fits tight spaces and small nuts, an 8-inch is the all-around size, and a 10-inch handles larger fittings and gives more leverage. Two-piece sets usually skip the 8-inch, which is the size you'll use most, so a three-piece set is the safer first buy.
Jaw Capacity
Capacity varies more than you'd expect between brands. Here's how the 10-inch wrenches compare, per each manufacturer:
| 10-inch wrench | Max jaw capacity |
|---|---|
| Crescent (AC3PC, AC26810CV) | 1-5/16" (34 mm) |
| Milwaukee (48-22-7400) | 1-3/8" |
| GearWrench (89750) | 1-7/16" (37 mm) |
If you work on larger plumbing fittings or big nuts, a wider capacity can save you buying a 12-inch wrench.
Jaw Design and Slippage
Adjustable wrenches slip when the jaw has play or the screw creeps open. Look for a tight, stable jaw (Crescent's tension spring), a screw that resists backoff (Milwaukee, GearWrench), and a contact design that loads the flats (GearWrench's off-corner loading). Always pull so the force goes toward the fixed jaw.
Head Thickness
A slim head reaches nuts in tight spaces, like under a sink or behind a bracket. GearWrench calls out a slim head on the 89750. If a thin wrench is what you need most, our upcoming thin wrench set guide covers fixed-size options.
Scales and Markings
Laser-etched SAE and metric scales let you set the jaw before you reach in. Crescent, GearWrench and Milwaukee all list them. They're a small feature that makes a big difference in awkward spots.
Adjustable vs Fixed Wrenches
For car work, a fixed combination wrench is faster and grips better. Use an adjustable wrench for odd sizes, backing up a bolt head, and plumbing. A complete wrench set should still be your main tool, and our best mechanic tool set picks bundle wrenches with sockets. Our essential mechanic tools list shows where an adjustable fits in a starter kit. Never use an adjustable on brake or fuel line fittings; that's what a flare nut wrench set is for.
Pipe Work
A standard adjustable wrench isn't a pipe wrench. Its smooth jaws can slip on round pipe and crush thin tubing. For occasional work on small pipe, the GearWrench GWPTAW8's reversible serrated jaw handles pipe up to 1". For anything larger or seized, use a proper pipe wrench, and use smooth jaws on chrome fixtures to avoid marring them.
Warranty
Crescent, GearWrench and Craftsman list full lifetime warranties on these sets. Milwaukee lists a Limited Lifetime Warranty on its adjustable wrenches. The GearWrench GWPTAW8 has no warranty on the set as a whole, only on individual items.
How We Chose
We compared current adjustable wrench sets from Crescent, GearWrench, Milwaukee and Craftsman using each manufacturer's published specs: included sizes, maximum jaw capacity, jaw and screw design, scales, handle design, finish, storage and listed warranty. We also considered recurring owner feedback on adjustable wrenches, especially jaw play and screws that back off under load. We did not test these wrenches ourselves; where a manufacturer doesn't publish a spec, such as Craftsman's jaw capacities, we say so.
FAQ
What sizes should an adjustable wrench set include?
A 6-inch, 8-inch and 10-inch set covers most household, plumbing and automotive needs. The 6-inch fits tight spaces and small nuts, the 8-inch is the everyday size, and the 10-inch handles larger fittings up to about 1-5/16 to 1-7/16 inches depending on the brand.
Is a crescent wrench set the same as an adjustable wrench set?
Yes. Crescent is a brand that popularized the adjustable wrench, and "crescent wrench" became the common name for the tool. Crescent still makes adjustable wrench sets, like the AC3PC, alongside GearWrench, Milwaukee, Craftsman and others.
Can an adjustable wrench replace a wrench set?
Not for car work. An adjustable wrench is slower to set and more likely to slip and round a tight fastener than a fixed-size combination wrench. Use it for odd sizes, plumbing fittings and as a backup, and keep a combination wrench set for regular work.
How do you keep an adjustable wrench from slipping?
Tighten the jaw snugly on the flats, and turn the wrench so the force pushes toward the fixed jaw, not the movable one. Wrenches with a thumbscrew that resists backing off, like Milwaukee's proprietary adjustment screw or GearWrench's knurled screw, help hold the setting.
What does jaw capacity mean on an adjustable wrench?
It is the widest opening the jaws can reach, which sets the largest nut or fitting the wrench can grip. Two 10-inch wrenches can have different capacities: Crescent lists 1-5/16 inches for its 10-inch AC210VS, Milwaukee 1-3/8 inches and GearWrench 1-7/16 inches.
Verdict
The Crescent AC3PC is the best adjustable wrench set for most people: 6, 8 and 10-inch wrenches with a stable hex jaw, SAE and metric scales and a full lifetime warranty. Choose the GearWrench 89750 if you need the widest jaws and off-corner grip for automotive work, or the Crescent AC26810CV if comfort on long jobs matters most.
