Tenterhooks were used as far back as the fourteenth century in the process of making woollen cloth. After the cloth was woven it still contained oil from the fleece and some dirt. A fuller (also called a tucker or walker) cleaned the woollen cloth in a fulling mill, and then had to dry it carefully or the wool would shrink. To prevent this shrinkage, the fuller would place the wet cloth on a large wooden frame, a "tenter", and leave it to dry outside. The lengths of wet cloth were stretched on the tenter (from the Latin "tendere", to stretch) using hooks (nails driven through the wood) all around the perimeter of the frame to which the cloth's edges (selvedges) were fixed so that as it dried the cloth would retain its shape and size.[1] At one time it would have been common in manufacturing areas to see tenter-fields full of these frames.

 

By the mid-eighteenth century the phrase "on tenterhooks" came into use to mean being in a state of uneasiness, anxiety, or suspense, stretched like the cloth on the tenter. [2]

 

Sometimes these are confused with "tent hooks". Tent hooks have none of the connotations listed above, but are significantly more practical if you need to tie down a tent.

Y'all might be interested to know that the word "tenter" is also used in the polymer film manufacturing industry to mean a long heated oven (like football field length) through which a cast web is pulled, stretched, and annealed. Each side of the tenter has something that looks like a giant bike chain on it with linked clasps that open on the outside and clamp down on the web as they cycle into the oven. A cast web might go into the tenter at one to two feet wide and several millimeters think and come out the other side a couple of yards wide and a few mils (1 mil = 0.001 inch = 25.4 microns is about 1/4 the thickness of a human hair). Film manufacturing engineers develop very sophisticated heating profiles down the tenter to optimize desired film characteristics. I have visited some film lines at 3M plants and they are very impressive bits of machinery indeed.
