🔧How to find combination wrenches that meet your needs? How do you know that the tool will deliver on its advertising promises in everyday use? What quality characteristics should you look for?
Anyone looking to purchase a new combination wrench or even a set of wrenches is quickly faced with an overwhelming selection of branded and unbranded products. But there is good news: it is not that difficult to separate the wheat from the chaff and find tools that will last you a long time.
🔧Safe work with little fatigue
Be sure to check the ergonomics of the combination wrench. It should fit well in your hand and the finish should offer you a good grip. This is the only way to ensure that you can work safely when you have to apply a little more force. Plus, comfortable handling and a natural grip position will protect your joints and allow you to work with less fatigue.
🔧Travel light
The weight of the combination wrench also affects ergonomics. Naturally, forged tools have a particularly high weight. This may not be noticeable with a single key. But when you have to transport a complete set, you'll be thankful for every gram you saved. For this reason we recommend combination wrenches with a concave shaft, which have a reduced weight. Like a double T profile, this design provides maximum flexural strength and load capacity with minimum weight.
🔧Be aware of small spaces
If you frequently work in tight spaces, you should always use slim profile combination wrenches. These help you reach hard-to-reach places.
🔧Check manufacturing tolerances
The more precisely a combination wrench is manufactured, the tighter it will fit the screw head. The result is a perfect friction joint. That is to say: the applied force is optimally transmitted to the screw. And not only that: the smaller the clearance between the jaws or flanks of the key ring and the screw, the safer and more precise it will be to work with it without damaging the screw head.
🔧Identify critical areas of tension
When choosing your combination wrench, also pay attention to the transition between the shaft and the socket or ring. This is where the greatest forces are applied when tightening. Therefore, this critical stress zone must be slightly more stable, i.e. wider, in order to minimize the risk of breakage and injury.
Lastly, but also very important: choose a brand name manufacturer that you can easily order from and that offers a wide range of combination wrenches. This way you can add other devices you need, such as TORX or Unit-Drive, to your tool!
