Using your Wera 354 8mm x 100mm Hex Screw Driver is easy. Just pick the right size according to the color - coding on the handle base. Then insert the tip into the hex bolt and start turning. When using, hold the Kraftform handle firmly for better control. Remember, the non - roll design of the handle lets you place it on angled surfaces safely. To keep your screwdriver in good shape, clean it after each use with a dry cloth. The Wera Black Point tip provides corrosion protection, but avoid leaving it in damp conditions.
