Using this Wera 354 3mm x 75mm Hex Screwdriver is easy. Just pick the right tool using the color - coded system on the handle base. Then, place the tip firmly on the hex bolt head and turn it. When you're done, you can put it on an angled surface without worrying about it rolling away. For maintenance, keep it clean. You can wipe it with a dry cloth after use. If it gets dirty, you can use a mild cleaner. Avoid using it on bolts that are too big or too small for the 3mm tip, as this may damage both the tool and the bolt. Also, store it in a dry place to prevent corrosion.
