The job isn’t finished until everything is tightened down. Precision insulated tools fit and grip the fastener properly to apply maximum torque without damage to the head. Hardened chromium-molybdenum-vanadium (CMV) steel blades minimise wear. The last thing you want is to have your driver slip out of the screw head and possibly contact a nearby live conductor.
Fluke offers two sizes of square head screwdrivers. Both certified to 1000 volts AC and 1500V DC. Every screwdriver individually tested to 10,000 volts and backed by a limited lifetime warranty.
