Nuts & Bolts
WE DID THE HOMEWORK.
A bolt’s utility is not determined simply by whether it fits into a hole, but rather a series of particular specifications: type of bolt, physical dimensions, thread density, forming material, and tightening requirements.
The greater the torque, or turning force, the greater the pressure pulling the nut forward along the threads. This in turn creates tension in the bolt and a clamping force that presses the two components together. A higher number or a denser arrangement of threads can strengthen the joint.
