I keep 2 of them on the truck- a 1/4" drive and a 3/8" drive ratcheting "clicker" wrenches. I always torque meterbase lugs and the main lugs in the disconnect/loadcenter to the listed specs. I have a set of 3/8" and 1/4" allen sockets. I'd like to have a Klein torque screwdriver but it costs more than my Snapon 3/8 torque wrench!
