So what's wrong with 18mm spanners?
So there I am with a pack of M12 flange nuts and lots of threaded rod,
and I need an 18mm spanner... Except the first set I try goes from 17mm to 19mm, so I look at my socket set, same. Another socket set, same. The deep socket set included with the pneumatic impact wrench, same again! Had to use an adjustable in the end! -- Cheers, John. /================================================== ===============\ | Internode Ltd - http://www.internode.co.uk | |-----------------------------------------------------------------| | John Rumm - john(at)internode(dot)co(dot)uk | \================================================= ================/ |

I have come across a few 18mm bolts on Japanese cars. |

An M12 nut is *supposed to be* 19mm across the flats, don't see why a flanged nut should be different? |

No notice enclosed " for your convenience this set does not include an 18mm option"?

This link suggests that the ISO standard is 18mm: https://amesweb.info/Fasteners/Nut/M...ons-Chart.aspx This link suggests that the ISO standard is, as above, 18mm, but the DIN standard is 19mm. https://www.fastenerdata.co.uk/techn...omparison.html As does Wiki: https://en.wikipedia.org/wiki/ISO_metric_screw_thread |

Thanks to the internet they are not to difficult to get, but in the past I saw the solution was to file down the next size up. |

Had to use an adjustable in the end! In comparative ignorance here, but isn't 18mm 3/8" Whit and/or 7/16" BSF? I have sets of Whit and BSF spanners from the days of tinkering with my MG TC. Isn't it 11 or 12 mm that is often missing from some sets, I suspect there is a preferred set of sizes in a standard somewhere. Also quite a lot of Allen key sets are missing 7mm, which is common on brake calipers. |

Just have to hope I don't need a deep socket for a 13 or a standard socket for a 12 - but at least it does have both. |

I always wonder at the 'missing' 12 or 13 mm spanners as both sizes are very common, in fact it seems quite common to have 12mm bolts with 13mm nuts which can be very confusing sometimes. I have so many socket sets around that I think I can find every mm size from 4 (or even less) up to something well past 30. I just needed a 27mm (for removing FJR1300 rear wheel - puncture!) and I have a 3/4" drive set with that. I have got some 46mm spanners and sockets, for the tractor. With the addition of AF spanners (of which I have a multiplicity) I can fit most nuts. (Hmm, is there a double entendre there?) -- Chris Green · |

With the addition of AF spanners (of which I have a multiplicity) I can fit most nuts. (Hmm, is there a double entendre there?) I recently bought an inexpensive set of Forstner bits going from 14 to, IIRC, 25, then a few larger ones. Total of 16. A large part of the reason was that all my other big hole bits (spade and Forstner) were both pretty crap and I always ended up needing sizes that were not included in sets. For example, a current Bosch spade bit set has 12, 16, 18, 20, 22, 25, 28 and 32mm (and listed at £17.99 from Screwfix) - in my book, stupid gaps. For a particular purpose, I'd bought one fairly cheap eBay 24mm Forstner bit and it worked very well. Hence, pushing the boat out. For less than £12 they are actually quite good. Sharp and clean cutting. |

Prefer Teng for 'Good'ones but am happy with el cheapo 24mm and over when I will have only occasional use. I do have one snap on 14mm spanner left in the engine compartment after a service |
