    Bolts are headed, externally threaded fasteners used to keep two objects, often metal or wood, in a fixed position relative to one another. Unlike screws, which cut their own threads, bolts pair with the internal threads of nuts to stay in place and ensure the desired level of tension in the bolted joint. The use of nuts aids in disassembly and reassembly.
