How do you measure torque on a bolt?
The marking check: After tightening the bolt, mark the bolt surface and that of the product or workpiece. Then loosen the bolt. Re-tighten it until the markings re-align. The torque needed to return the bolt to its original position is the torque value of the bolt.

What torque wrench should I buy?
The bigger the drive and the longer the handle, the more torque they can deliver. Most home mechanics will find that a torque wrench with a 1/2-inch drive and at least an 18-inch handle is the best choice for lug nuts, cylinder heads, suspension bushings, and other likely uses.
Do you torque the nut or bolt?
In simple terms, you need torque to create tension in a bolt. You use torque to turn a nut onto a bolt and then to stretch the bolt, making it a solid spring that clamps the two materials together.
