Craftsman 3/8-in Drive Micrometer Torque Wrench

Craftsman's 3/8-in Drive Micrometer Torque Wrench, model CMMT99433, is a tool that promises the precision and reliability that DIY enthusiasts and professionals alike have come to expect from the Craftsman brand. As someone who has spent a considerable amount of time working with various torque wrenches, I was curious to see how this particular model would perform, especially given the brand's storied reputation for quality.

Upon first handling the torque wrench, I was immediately impressed with its build. The bi-material handle offers a comfortable and secure grip, which is essential for maintaining control during use. The handle's ergonomic design ensures that you can apply pressure without experiencing discomfort, even during extended tasks. The full polish chrome finish not only gives the tool a sleek appearance but also provides a layer of durability, protecting it from rust and wear.

One of the standout features of this torque wrench is its locking mechanism. The spring-loaded handle lock design is intuitive and straightforward to use. To adjust the torque setting, you simply pull back and hold the locking collar, turn the handle to the desired setting, and then release the collar to lock it in place. This mechanism ensures that the handle remains in the locked position during use, preventing any accidental changes to the torque setting. This is a significant improvement over older models that used a twist-lock collar, which could sometimes be cumbersome to operate.

The tool comes with scales stamped into the housing for both inch and metric torque settings, making it versatile for various applications. This dual-scale feature is convenient for users who frequently switch between different measurement standards. Additionally, the torque wrench comes with a torque certification certificate, providing assurance of its accuracy. The inclusion of a durable plastic case for storage and portability is a thoughtful touch, protecting the tool when not in use and making it easy to transport.

In terms of performance, the torque wrench delivered consistent and reliable results in my testing. I used it for several tasks, including changing a lawn mower blade and performing routine maintenance on my vehicle. The click mechanism, which signals when the desired torque is reached, was clear and easy to detect. This audible and tactile feedback is crucial for ensuring that you don't over-tighten bolts, which can lead to damage or failure.

However, it's worth noting that while the tool performed admirably in most scenarios, there were some limitations. For lower torque applications, specifically those requiring less than 20 ft-lbs, the click was less pronounced. This made it challenging to determine if the desired torque had been reached, potentially leading to over-tightening. For high-precision applications, you might want to consider a torque wrench specifically designed for low torque ranges or even a digital model for more accurate readings.

Durability is another area where the Craftsman torque wrench shows mixed results. While the overall construction feels robust, there have been instances where the ratcheting mechanism developed issues after extended use. In one case, the mechanism locked up, necessitating disassembly and lubrication to restore functionality. This could be a point of concern for users who rely on their tools for frequent, heavy-duty tasks.

Despite these minor drawbacks, the torque wrench remains a reliable tool for general use. Its ease of use, combined with the locking mechanism and comfortable handle, makes it suitable for a wide range of applications. The 1-year limited warranty offers some peace of mind, although it falls short of the lifetime warranty that many long-time Craftsman users might expect.

In conclusion, the Craftsman 3/8-in Drive Micrometer Torque Wrench is a solid choice for those in need of a reliable and easy-to-use tool for moderate torque applications. Its ergonomic design, intuitive locking mechanism, and dual-scale measurements make it versatile and user-friendly. While it may not be the best option for low torque precision tasks or frequent heavy-duty use, it performs well for most general applications. The included case and torque certification are added bonuses that enhance the overall value of the tool.

I would recommend this torque wrench for hobbyists and DIY enthusiasts who need a dependable tool for occasional use. Its ease of use and comfortable design make it a pleasure to work with, and the price point is reasonable for the features it offers. However, for professionals or those requiring high precision and durability under heavy use, it might be worth investing in a more specialized or higher-end model.
