Wrenches
Wrenches are the tools used to turn nuts and bolts. There are many types and sizes of wrenches. The common types are open-end wrench, box-end wrench, socket wrench and adjustable wrench. The common sizes of wrenches are 6 mm, 8 mm, 12 mm and 14 mm. When you use a wrench, you should follow the proper steps. Firstly, choose a wrench of the right size and type for your work. Secondly, check the wrench teeth. Are they clean and sharp? Thirdly, fit the wrench correctly on the bolt or nut before you apply pressure. Finally, turn the bolt or nut in a slow and steady motion. Remember, wrenches should be used with care and be stored properly.
