Torque wrenches are usually described by their drive size, which in turn indicates the bits you can use to tighten fasteners. The torque wrench size significantly impacts its functioning since the bigger the drive size and the longer the handle, the more torque it can deliver. There are varied sizes, all of which work to suit different tasks best. Some common roles for torque wrenches are fastening car parts, including;

• Wheels
• Connecting rods
• Suspension bushing
• Struts
• Calipers 
• Intake manifold
• Cylinder heads

You may also need them on lawnmowers, mopeds, your HVAC, generators, etc. Having the right size makes your work easier and safer. Occasionally, two torque wrenches may crossover in function, but normally they are all geared to different roles.
