A torque wrench is a specialized tool used to tighten fasteners (Nuts & bolts) to a precise factory spec setting.

This set carries both metric and standard sockets and that's important, because some mowers will have both type of fastener sizes. Set includes spark plug sockets. Picture links to Amazon.com
