What is a bolt primarily used for in metalworking?

A bolt is primarily used to fasten parts together, which is a fundamental operation in metalworking and assembly processes. Bolts work in conjunction with nuts to create secure joints that hold components in a fixed position, even under varying conditions such as stress, vibration, or thermal expansion.

In metalworking, ensuring that different pieces stay properly aligned and are joined securely is crucial for the integrity and functionality of the final product. The design of a bolt allows for these joints to be tightened or loosened as necessary, providing versatility in assembly and maintenance.

While bolts can support loads as they help in securing materials, that specific function of load support depends on the fastening action rather than being the primary purpose. Additionally, creating holes and cutting materials are functions associated with other tools and processes rather than the specific application of a bolt. Therefore, the emphasis on fastening parts highlights the primary role that bolts play in metalworking operations.
