Wrenches Tools
Wrenches are a huge part of any tool set and have a variety of uses. They are mainly used for tightening and loosening. There are two mainstream type of wrenches; Open end and Combination.
An open end wrench is a great tool. This wrench is often double-ended, with a different-sized opening at each end. The ends are generally oriented at an angle of around 15 degrees to the longitudinal axis of the handle. This allows a greater range of movement in enclosed spaces by flipping the wrench over.
Combination wrenches have one end like an open end wrench and the other side with a circular design. Both ends usually fit the same bolt. There are many more types of wrenches, and depending on the job, will determine what wrench you will ultimately end up needing.
