Brads, also five letters long, are small nails with a wide head that are used to hold two pieces of material together. LATCHES, seven letters long, are devices used to keep doors and windows closed. Lastly, RIVETS, six letters long, are cylindrical fasteners that are inserted through two pieces of material and then expanded to hold them together.
