Which wrenches are described as coming in sets with standard sizes and not interchangeable?

Socket wrenches are designed to work with a specific set of sockets that correspond to standard sizes, typically following either metric or standard measurements. Each socket is designed to fit a particular size of nut or bolt head, meaning that socket wrenches are not interchangeable in terms of the sockets they use; a specific socket must match the size of the fastener being worked on. This allows for greater torque application and reduces the risk of rounding off the corners of fasteners, which can happen with other wrench types.

In contrast, open-end wrenches and box wrenches can often fit various sizes due to their design, allowing for some interchangeability as long as the wrench can fit around the nut or bolt. Torque wrenches, while specialized, are adjustable and often accompanied by specific instructions on settings, allowing them to be used on a range of fasteners rather than being limited to a specific size.
