Is it true or false that the inside diameter of a washer must always be slightly smaller than the diameter of the fastener?

True
False
Depends on the application
Only for large fasteners

The correct answer is: False

In this context, it is false that the inside diameter of a washer must always be slightly smaller than the diameter of the fastener. Washers serve various purposes, including spreading the load of a fastener and preventing damage to the surface being fastened. The sizing of a washer is determined by several factors, such as the type of fastener being used, the application, and the specific requirements of the assembly. While some washers may be designed with an inner diameter that is slightly smaller than the fastener to ensure a snug fit, others may have an inner diameter that matches the diameter of the fastener or is larger, especially in applications where a loose fit is acceptable or necessary for movement or flexibility. Therefore, it's important to consider the specific requirements of each situation rather than adhering to a strict rule regarding washer sizes in relation to fasteners.
