Park Tool Hex Wrenches: Which Set Fits Your Bike Toolbox?

Park Tool is the name most bike shops trust for repair tools, and its blue-handled hex wrenches are a familiar sight on workbenches. Hex wrenches, also called Allen keys, turn the six-sided sockets found in bolts all over a modern bicycle: stems, seat posts, brakes, derailleurs and bottle cages. For a new home mechanic or a gift-giver, the right Park Tool hex set can handle most basic adjustments without a trip to the shop.
The six Park Tool products below differ mainly in shape and size coverage: a palm-sized 3-way wrench, a fold-up pocket set, three full sets with P-handle, L-shape and sliding T-handle designs, and a socket and bit set that works with a ratchet or torque wrench as a step up.
Park Tool Hex Wrench Sets Compared
| Model | Design | Hex Sizes | Steel |
|---|---|---|---|
| AWS-1 | 3-way Y-shape | 4, 5, 6mm | Hardened tool steel |
| PH-1.2 | P-handle with ball ends, holder | 2, 2.5, 3, 4, 5, 6, 8, 10mm | Protanium high-torque steel |
| HXS-1.2 | L-shape keys | 1.5, 2, 2.5, 3, 4, 5, 6, 8, 10mm | Protanium high-torque steel |
| AWS-10 | Fold-up | 1.5, 2, 2.5, 3, 4, 5, 6mm | Hardened tool steel |
| SBS-1.3 | 3/8 inch drive sockets and bits | 3, 4, 5, 6, 8mm bits plus others | Chrome vanadium |
| THH-1 | Sliding T-handle | 2, 2.5, 3, 4, 5, 6, 8, 10mm | Chrome vanadium and S-2 |
A quick word on sizes. Bikes use metric hex bolts, and the 4mm, 5mm and 6mm sizes cover a large share of everyday jobs such as stems, seat clamps and brake mounts. Smaller sizes like 2mm, 2.5mm and 3mm appear on derailleur limit screws and small parts, while 8mm and 10mm show up on crank bolts and some pedals. “Chamfered” tips have slightly angled edges so they slide into a bolt head cleanly without rounding it.

Park Tool AWS-1 3-Way Hex Wrench
Best for: Stocking stuffer for any new cyclist
Pros
- Covers 4, 5 and 6mm
- Fits in the palm
- Hardened tool steel
- Chamfered tips
Cons
- Only three sizes
The Park Tool AWS-1 3-Way Hex Wrench is a Y-shaped tool with three arms: 4mm, 5mm and 6mm. Park Tool says it introduced the 3-way hex wrench to the bike world more than 30 years ago, and the design fits in the palm while giving good leverage. You grip two arms and turn with the third.
The wrenches are made from industrial tool steel, hardened and tempered for long life, with chamfered tips. It weighs 2.4 ounces and the listing gives a length of 9 inches, which likely refers to the overall packaged or tip-to-tip measurement.
The AWS-1 suits almost every new cyclist and makes an easy stocking stuffer. Because it only has three sizes, it will not reach small derailleur screws or large crank bolts, where a full set such as the PH-1.2 or HXS-1.2 is needed.
Park Tool PH-1.2 P-Handled Hex Wrench Set for the Workbench
Park Tool
Park Tool PH-1.2 P-Handled Hex Wrench Set with Holder Tool, Blue
Price and specifications are read from the Amazon product page and can change.
Park Tool PH-1.2 P-Handled Hex Wrench
Best for: Home mechanics setting up a workbench
Pros
- Eight sizes, 2 to 10mm
- Ball ends for angled bolts
- Comfortable nylon P-handles
- Holder included
Cons
- No 1.5mm size
- Spec sheet has odd details
The Park Tool PH-1.2 P-Handled Hex Wrench set is the classic shop set. It includes eight sizes, 2, 2.5, 3, 4, 5, 6, 8 and 10mm, each with a P-shaped nylon handle designed for comfort. The offset handle works like a small lever for loosening tight bolts, while the long shaft lets you spin bolts quickly.
Each wrench has a ball end, a rounded tip that lets you turn a bolt from an angle when you cannot line up straight, which is common around bottle cages and brakes. The steel is described as Protanium high-torque industrial steel, and a holder keeps the set organized. The set is made in the USA and covered by Park Tool’s limited lifetime assurance. A few specification fields look off, such as a 10mm length and an aluminum material, and it lists “T-Handle” as its style even though the handles are P-shaped, so rely on the feature list.
This is the gift for someone setting up a home workbench. If you want the tiny 1.5mm size too, the HXS-1.2 includes it.
Park Tool Allen HXS Wrench-1.2 1.5 Set for Full Size Coverage
Park Tool
Park Tool Allen HXS Wrench-1.2 1.5/2/2.5/3/4/5/6/8/10

Park Tool Allen HXS Wrench-1.2 1.5
Best for: Budget full set for home repairs
Pros
- Nine sizes, 1.5 to 10mm
- Precision chamfered tips
- High-torque steel
Cons
- Plain L-shape, less comfortable
- No ball ends listed
The Park Tool Allen HXS Wrench-1.2 1.5 to 10mm set is a traditional L-shaped key set with nine sizes: 1.5, 2, 2.5, 3, 4, 5, 6, 8 and 10mm. It covers the widest range of hex sizes of any set here.
The tips are precision chamfered for a tight fit, and the keys are made from the same Protanium high-torque steel named on the PH-1.2. The set weighs 3.52 ounces. The listing does not mention ball ends or a holder, so expect plain L-keys, which offer good leverage from the long arm but are less comfortable than padded handles during long sessions.
The HXS-1.2 suits home mechanics who want every size in one simple set. For comfort and quick spinning, the PH-1.2 or THH-1 is more pleasant to use. For a look at other precision key sets, see our Allen wrench guide.
Park Tool AWS-10 Fold-Up Hex Wrench Set for Riding
Park Tool
Park Tool AWS-10 Fold-Up Hex Wrench Set
Price and specifications are read from the Amazon product page and can change.
Park Tool AWS-10 Fold-Up Hex Wrench
Best for: Riders who want a pocket toolkit
Pros
- Seven sizes, 1.5 to 6mm
- Folds into one tool
- Hardened tool steel
Cons
- No 8mm or 10mm
- Less leverage than full-size keys
The Park Tool AWS-10 Fold-Up Hex Wrench set works like a pocket knife: seven hex keys, 1.5, 2, 2.5, 3, 4, 5 and 6mm, fold into a single blue body. You unfold the size you need and use the body as a handle.
Like the AWS-1, the wrenches are industrial tool steel, hardened and tempered, with chamfered tips. The listing weight of 23 grams makes it very light, although that figure seems low for seven steel keys, so treat it as approximate.
The AWS-10 suits riders who want a small tool for a saddle bag or jersey pocket. It lacks 8mm and 10mm sizes and gives less leverage than full-size keys, so pair it with a workshop set at home.
Park Tool SBS-1.3 Socket and Bit Set as a Step Up
Best for: Torque wrench owners upgrading their kit
Pros
- 18 sockets and bits
- 3/8 inch drive
- Torx-compatible bits
- Chrome vanadium steel
Cons
- Needs a separate ratchet or torque wrench
- Heavier at 2.1 pounds
The Park Tool SBS-1.3 Socket and Bit set is different from the wrenches above. It is an 18-piece set of sockets, hex bits (3, 4, 5, 6 and 8mm) and Torx-compatible bits, all with a 3/8 inch drive. A drive is the square hole that attaches to a ratchet handle, a breaker bar or a torque wrench.
The reason to own a set like this is torque. Many modern bike parts, especially carbon ones, have a recommended tightness, and a torque wrench lets you hit it precisely. The SBS-1.3 is made from chrome vanadium steel with a silver finish, weighs 2.1 pounds and carries a limited warranty. The listing names “Ratchets and Bits” as included components, but the feature list describes only sockets and bits, so we cannot confirm a ratchet is in the box.
This set suits enthusiasts who already own, or plan to buy, a 3/8 inch torque wrench or ratchet. First-time mechanics are better served by a hex set.
THH-1 Sliding T-Handle Hex Wrench Set for Speed and Leverage
Best for: Frequent wrenchers who want speed
Pros
- Sliding T-handle leverage
- Speed Spinner for long bolts
- Eight sizes, 2 to 10mm
Cons
- No 1.5mm size
- Weight listing appears wrong
The THH-1 Sliding T-Handle Hex Wrench Set includes eight sizes, 2, 2.5, 3, 4, 5, 6, 8 and 10mm. The T-handle slides along the shaft, so you can center it for even two-handed torque or push it to one side for more leverage and access in tight spots.
Each handle includes an anodized aluminum Speed Spinner, a small spinning grip that lets you run long bolts in and out quickly with your fingertips. The shafts use a mix of chrome vanadium and S-2 tool steels. The listed weight of 1.72 grams is clearly an error for a set of this size, and the listing does not mention whether a holder is included.
The THH-1 suits riders who work on bikes often and want the fastest, most comfortable set. If you need the 1.5mm size, add the HXS-1.2 or AWS-10.
How to Choose the Right Park Tool Hex Wrench Set
Start with where you will use it. For roadside fixes, the AWS-10 fold-up or AWS-1 3-way is compact. For a home workbench, choose a full set: PH-1.2, HXS-1.2 or THH-1.
Next, check sizes. The HXS-1.2 covers the most, from 1.5mm to 10mm. The PH-1.2 and THH-1 cover 2 to 10mm. The AWS-1 covers only the everyday 4, 5 and 6mm.
Then think about comfort and speed. P-handles and ball ends help with awkward angles, the sliding T-handle adds leverage and speed, and L-keys are simple and sturdy. If you are building a broader toolkit, our tool set guide covers general-purpose options.
Finally, if you work on carbon parts, pair a torque wrench with the SBS-1.3 socket and bit set.
FAQ
What hex sizes do most bikes use?
The 4mm, 5mm and 6mm sizes handle many common jobs, which is why the AWS-1 includes exactly those three. Smaller and larger sizes appear on specific parts.
