The job isn’t finished until everything is tightened down. Precision insulated screwdrivers fit and grip the fastener properly to apply maximum torque without damage to the head. Hardened German 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.
This insulated screwdriver set includes three sizes of slotted, two sizes of Phillips and two sizes of square screwdrivers. All certified to 1000 volts AC and 1500V DC. Every screwdriver individually tested to 10,000 volts. All back by a limited lifetime warranty.
