Craftsman 10Pc Mm Stubby Combo Wrench Set Review
Navigating tight spaces with precision can often be a challenge, but with the Craftsman 10Pc Mm Stubby Combo Wrench Set (CMMT42339), I found a reliable partner. This set includes 10 miniature combination wrenches ranging from 4mm to 11mm, making it versatile for a variety of tasks, from automotive work to small home repairs.
The first thing that caught my attention is the set's design. These wrenches are designed to be compact, perfect for getting into those hard-to-reach areas. The combination of open and box ends provides the flexibility needed to tackle different types of fasteners without having to switch tools constantly. This versatility is a significant advantage, especially when working in confined spaces where maneuverability is limited.
One of the standout features is the Full Polish Chrome finish. Not only does it give the wrenches a sleek, professional look, but it also offers excellent resistance to corrosion and rust. This is particularly important for tools that might be exposed to various elements, ensuring they remain in good condition over time. The transparent pouch that comes with the set is a nice touch, allowing for easy size identification and organization.
However, the set isn’t without its shortcomings. The wrenches are noticeably thicker compared to older models. While this can be seen as an attempt to increase durability, it also makes them feel a bit unrefined. The edges aren’t as smooth as I would have liked, and there are visible shearing marks under the chrome finish. This lack of refinement can be a bit disappointing, especially for those who have used Craftsman tools for years and have come to expect a certain level of quality.
The fit of the wrenches is another area where I found room for improvement. Some sizes fit snugly on fasteners, while others feel a bit loose. This inconsistency can be problematic, particularly when working with critical fasteners in tight spots. The 12-point design, while useful for gripping, can sometimes be a double-edged sword. If not used carefully, there’s a risk of rounding off fasteners, which can cause additional headaches.
Despite these issues, the wrenches proved their worth in several situations. For instance, while working on a motorcycle carburetor, the smaller sizes were indispensable. They allowed me to reach and adjust components that larger wrenches simply couldn’t access. Similarly, during a home project involving the installation of a new faucet, the wrenches made it easy to navigate the cramped space under the sink.
The set’s portability is another plus. The lightweight and compact design make it easy to carry around, whether in a tool bag or even in a pocket. This is especially useful for professionals who need to move between job sites frequently. The lifetime warranty offered by Craftsman is also reassuring, providing peace of mind that these tools are built to last and will be replaced if they fail.
In terms of overall build quality, the wrenches are made of steel, which adds to their durability. However, the feel of the material suggests that it’s a milder steel compared to older Craftsman models. This might be a trade-off to keep the cost down, but it does make the wrenches feel less robust.
One of the most significant advantages of this set is its availability of small metric sizes, which are often hard to find. This makes the set particularly valuable for tasks that require precision and smaller tools, such as working on radio electronics or RC cars and trucks. The variety of sizes ensures that you have the right tool for almost any small-scale job.
In conclusion, the Craftsman 10Pc Mm Stubby Combo Wrench Set offers a mix of strengths and weaknesses. On the positive side, it is versatile, corrosion-resistant, and comes with a transparent pouch for easy organization. The compact design makes it ideal for tight spaces, and the lifetime warranty adds a layer of security. However, the thicker, less refined build and inconsistent fit are notable drawbacks. While it may not meet the high standards set by older Craftsman models, it still performs well for a variety of tasks and is a handy addition to any toolbox.
Would I recommend this set? Yes, but with reservations. If you’re looking for a set of wrenches that can handle tight spaces and don’t mind a bit of a compromise on fit and finish, this set is a good choice. It’s particularly useful for those who need smaller metric sizes that are hard to find. However, if you’re a professional who requires absolute precision and a high-quality finish, you might find this set lacking. Overall, it’s a practical and affordable solution for everyday tasks, but it doesn’t quite live up to the legacy of Craftsman’s older tools.
