The spanner set is an item that holds all of the different sized spanners, a screwdriver, the sparkplug wrench and the ruler (for measuring tyre wear). The spanner set can be opened by looking at the side that has the handle and pressing F. Tools can be picked up from the opened spanner set by first pressing 2 to enter tool mode, and then pressing LMB on the desired tool.

Tools cannot be placed back inside the spanner set, they can only be swapped. This does not affect gameplay in any way, simply press 1 to go back to normal hand mode when the held tool is not needed anymore.
