Which statement is TRUE concerning the difference between bolts and screws?

The statement that a bolt is typically used in conjunction with a nut is true. Bolts are designed for use in securing materials together and often require a nut to create a strong connection. When a bolt passes through materials and is then fastened with a nut on the opposite side, this configuration provides significant clamping force and joint strength. This is particularly important in applications requiring high levels of tension and stability.

In contrast, screws typically have their own threads that allow them to be driven directly into materials, such as wood or metal, without needing a nut for fastening. Hence, the nature of their design and application is fundamentally different; bolts engage with nuts, while screws function independently.

The other statements do not hold true in the context of general fastener usage. A screw is not always longer than a bolt, as their lengths vary widely depending on their specific applications. A screw does not require a nut to function; instead, it relies on being threaded into a material for a secure hold. Lastly, bolts can indeed be used with wood materials, particularly in applications like furniture assembly or construction, where they can be paired with wooden pieces and nuts or used with washers.
