old combination spanner
I have an old combination spanner which on its
closed/ring side has an opening that has six, and not twelve sides as we are used to. Safe for clearance, are there any plus and minuses to this type of tool as compared to the "12s"? -- underground experts united http://user.it.uu.se/~embe8573 |

Generally speaking 6 sided wrenches are either the cheap wrenches or those designed for really high loads. High loading as the 6 sides fit the hexagon bolt head or nut more closely and cheaper because the broach used to make the 6 sided hole are cheaper to make. -- Cheers, John B. |

I was recently looking at real wrenches recently, and 12 point combination wrenches are much cheaper than 6 points. That's from real made in the USA brands. I don't know if that's demand, or a result of production costs. -- sig 66 |

But I take it there would be a noticable difference. -- underground experts united http://user.it.uu.se/~embe8573 |

I have too Six point wrenches are less likely to round off fastener heads, and are more tolerant of slight buggered heads. They're my preference in situations where clearance isn't an issue, and where torque is high. For lower torque use, I use ratchecting combination spanners, which are all 12 point. Were I restricted to just one set, they would probably be 12 points. But who has only once set of wrenches? -- sig 49 |

But I take it there would be a noticable difference. Yes, there is a reason :-) Impact Wrench sockets are nearly all 6 point as they are much stronger and "grip" the bolt head better. A 6 point wrench has to be turned 60 degrees between flats while a 12 point requires only half that number. Thus the 12 point can be used when there is less room to turn the wrench. A 6 point wrench (depending on tolerances) bears on the entire length of the 6 flats on a common bolt hear (or nut) while a 12 point bears on a much smaller portion of the flats. You can google on something like "Advantages of 6 point wrench". You'll get about 480 thousand replies. -- Cheers, John B. |

Yes, this is the clearance/speed advantage that has been touched upon. A 6 point wrench (depending on tolerances) bears on the entire length of the 6 flats on a common bolt hear (or nut) while a 12 point bears on a much smaller portion of the flats. Right, but is it the flats that pulls the nut/bolt head? Or the endpoints? But I suppose the endpoints, on a 6, has longer flats. (... did that last sentence make any sense BTW?)

I don't know if that's demand, or a result of production costs. I suspect it is more a matter of what type is most marketable. My comment about 6 point being cheap was based on seeing the absolute bottom of the pile wrenches that were all 6 point. -- Cheers, John B. |
