Wrenches / box wrenches / ratchet wrenches are all tools used to tighten and remove nuts and bolts. Wrenches have open ends and are mainly used for tacking. Box wrenches have ring-shaped ends that fit nuts and bolts, and an offset type is commonly used. There is also a short type that can be used when working in tight spaces, as well as a straight type that is easy to work within recessed sections. Ratchet wrenches feature a ratchet mechanism that makes it possible to work efficiently by enabling repeated tightening actions without having to reset the wrench on the bolt. All these wrenches are commonly made of tool steel, but there are also aluminum wrenches that are lightweight and useful for carrying around. Choose a product that matches the bolt size according to the application.
