Greenlee 0254-31 9-Piece Metric Folding Hex-Key Set

Using the Greenlee 0254-31 9-Piece Metric Folding Hex-Key Set is easy. Just unfold the set and pick the right size hex key for your job. Make sure to apply steady pressure when turning to avoid stripping the fastener. Remember, this is not an insulated tool, so don't use it in electrical work. To keep it in good condition, wipe it clean after each use. The powder-coated handle/case resists corrosion, but if you notice any signs of rust, clean it with a mild solvent. Thanks to its heat treatment and tempering, it's strong and durable, but don't use it for tasks that exceed its capabilities. With a lifetime limited warranty, you can trust this set for your DIY or professional projects.
