T-bolts are fasteners that are threaded and have a male thread on the outside. Screws and T-bolts are very similar in many ways. People often get confused about bolts and screws. T Bolts are often used to make a joint that is bolted together. The shanks of the T Bolts act like dowels and pin the joint against sideways shear stresses, while the nut applies a clamping force along the length of the bolt. Because of this, many T Bolts have a plain, unthreaded shank, which is also called the grip length. This makes a better, stronger dowel.
