Professional Trades and Heavy Fastening

This screwdriver suits electricians and mechanics who regularly drive large slotted screws and need the leverage of a wrench on the shank. It is not intended for Phillips, Torx, or precision screw profiles. Buyers who require insulated handles for live electrical work should select a different tool.
