This set includes flex head ratchet style spanners that have the versatility of an open end spanner with a flex head ratcheting ring end to make life easier in those tight places. All of these spanners are now thinner and lighter than both older models (and a lot of their competition), which reduces user fatigue without compromising on durability. The full range of ToolPRO spanners are made from ultra-durable chrome-vanadium steel, and finished with a bright, mirror-like polish, making them practically immune from corrosion, and quite nice to look at. ToolPRO Spanners meet and exceed both DIN and ANSI standards, so you can be sure that they are sturdy enough to tackle any job you need done. And if that wasn’t enough, each spanner comes with a lifetime warranty giving you peace of mind over years of service in the workshop. Whether you need a single spanner for a particular bolt, you’d like a well-rounded set for general purpose use, or you’d really like to make your tool-wall sparkle, check out the full range of ToolPRO spanners.
