Available in a multitude of sizes in both metric and imperial, there is a ToolPRO spanner suitable for taking care of almost any fastener. They come in sets of the most commonly used sizes, or as individual spanners - so you can pick the right spanner for any odd jobs you might have. All of these spanners are now thinner and lighter than both older models (and a lot of their competition), which reduces hand 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 to 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.
