What type of fastening screw can also be used in conjunction with nuts for varied applications?

The correct answer is machine screws. Machine screws are specifically designed for use in conjunction with nuts and are most often utilized in applications requiring a secure connection between metal components. These screws have a uniform diameter along their entire length and typically possess a flat or pan head that allows for a variety of drive styles, such as Phillips or slotted.

Machine screws are ideal for fastening parts where a secure, threaded connection is necessary, and they can easily be paired with nuts to enhance the fastening strength. This versatility makes them suitable for a wide range of applications, particularly in metalworking and machinery assembly.

In contrast, wood screws are designed primarily for joining wooden materials and do not typically require or work with nuts. Lag screws are heavy-duty fasteners used in wood and are designed to be driven into wood as opposed to being coupled with nuts, and Tec screws, also known as self-tapping screws, are meant for sheet metal applications or where a direct thread is formed and do not necessitate nuts for fastening.
