Combination lock function (ring wrench)
In addition to wrenches and ring wrenches, this one workshop tool is also quite widely used by automotive mechanics. It's called a combination lock. A combination wrench is also known as a ring wrench or combination wrench.
The combination lock is a combination of a wrench and a ring wrench. Yes, in the combination lock, we will find two kinds of locks in one tool handle. At one end, is a wrench, and at the other end is a ring wrench. Generally, combination locks have an offset of 15 degrees to the hilt, both offset at the end of the ring wrench and the end of the wrench.
For the size of the key, the combination lock only has one type of size in one key, for example, at the end of the wrench shape it has a size of 10 mm, then the other end which is in the form of a ring wrench will also have a size of 10 mm.

The function of the combination lock is to open or tighten the head of a bolt or nut that has a moderate tightening moment (not too big, not too small). In addition, the combination lock also serves to fill in the deficiencies of the wrench and ring lock.
Combination lock advantages and disadvantages
Because the combination lock consists of two lock models (ring and fitting), then we have the flexibility in determining which part to use. For example, when the head of a bolt or nut is in a narrow space, we can use a ring wrench to reach it. Meanwhile, to speed up the process of loosening the bolt head or nut, we can immediately replace it using a wrench.
Although it has the flexibility to choose the lock model that will be used according to the conditions, the combination lock also has some drawbacks when used, here are some of the drawbacks
- Cannot reach bolt heads and nuts that are hidden or in workpiece gaps.
- The tightening moment that can be done with a combination lock is quite small
