Using the Klein Tools K46 Slotted Screw - Holding Screwdriver is a breeze. First, wedge the split - blade tip into the slot of the slotted screw. Then, use the positive gripping action to hold the screw in place while you start and drive it into the desired spot, especially in those hard - to - reach areas. Remember, this screwdriver is not for torquing or tightening, so don't use it for those purposes. When it comes to maintenance, keep it clean by wiping it down after each use. Store it in a dry place to prevent the steel shank from rusting. And since the handle is made of plastic, avoid exposing it to extreme heat or sharp objects that could damage it.
