It comes from one of the processes of making woollen cloth. After it had been woven, the cloth still contained oil from the fleece, mixed with dirt. It was cleaned in a fulling mill, but then it had to be dried carefully or it would shrink and crease. So the lengths of wet cloth were stretched on wooden frames, and left out in the open for some time. This allowed them to dry and straightened their weave. These frames were the tenters, and the tenter hooks were the metal hooks used to fix the cloth to the frame. At one time, it would have been common in manufacturing areas to see fields full of these frames (older English maps sometimes marked an area as a tenter-field). So it was not a huge leap of the imagination to think of somebody on tenterhooks as being in an state of anxious suspense, stretched like the cloth on the tenter. The tenters have gone, but the meaning has survived.
