You’ve probably seen these wrenches included in tools kits that come with bikes, gas tools, or other machinery. Evidently in the UK these wrenches are called tubular box spanners, but what we call them here in the states escapes me. I’ve done a fair bit of searching and can’t find our name for them. Obviously we’re not going to call them spanners, and a search for “tubular box wrenches” turns up a completely different tool.
Made from high quality carbon steel and plated with zinc, this particular set of six spanners from Draper is double ended to fit 12 different Metric sizes: 8mm & 9mm, 10mm & 11mm, 12mm & 13mm, 14mm & 15mm, 16mm & 17mm, and 18mm & 19mm. The set also includes two “tommy” bars, 100mm and 150mm long.
This set of wrenches cost about 6 Euros or 8 dollars. If you know what to call these tools in American English, please drop a line in the comments.
