|+||The female screw in the head of a press, in which the [[s:spindle|spindle]] works. It is made of brass, and is usually cast on the screw of the spindle, round on the outside with a projecting part of about half an inch on the whole length of each opposite side, to keep it firm in the [[h:head|head]], and prevent it turning round. It is fitted tightly into the head, and kept in its place by two bolts, driven into the under side, with return heads which project over the bottom of the box. It is also called the Nut of the Spindle. |
