Available in a range of flat and Phillips head sizes, these insulated mini screwdrivers are designed for working with terminals and other electronic-based tasks. Comprised of top-grade insulated moulding, our insulated mini screwdrivers are extremely effective in protecting against electric shock and arcing up to 10,000 volts, making them perfect for carrying out electrical work.
