Which tool is used to fasten lugs and terminals?

• A. Torque wrench/screwdriver
• B. Nut driver/socket sets
• C. Crimpers
• D. Meggers

Answer: (B)

When securing lugs and terminals, the task is to tighten the nut or bolt that clamps the conductor in place. You need a tool that fits the nut precisely and can apply the right amount of turning force without slipping. A nut driver or socket set is designed for this exact purpose: you pick the correct size to match the nut on the lug or terminal, and the drive fits over and turns it efficiently, providing solid, secure connections. A torque wrench is useful when you must apply a specific torque, but for the basic fastening of lugs and terminals, the nut driver or socket set is the practical, versatile choice. Crimpers are for attaching crimp-on connectors to wires, not securing lugs with nuts, and megger devices are for insulation testing, not fastening.
