Using the Wera 350 PH 2 x 300mm Phillips screw driver is easy. Just insert the tip into the cross - recess screw and turn. The smooth hard zones are great for quick turning when you're in a hurry, and the soft grip zones give you extra power when you need more torque. When not in use, keep it in a dry place to prevent rusting. Since it has a color - coding system, it's easy to find the right one in your toolbox. The hexagonal shape helps it stay in place, so don't worry about it rolling off your workbench. If you notice any wear on the tip over time, it might be time to replace it. And remember, if you buy 3 or more Wera tools, you can get a 10% discount.
