I'm looking for accurate dimensions of this part so I can mount my pannier frames. I need depth of female thread, across flats of the hex, length of the hex, and length of the male threads. Thanks! In INCH please. Metric conversion is a pain for me even though I can do it well.

How do I post a picture on the forum?

Oops, mm

The spanner size is just about more or less 15 mm.

The diameter of the hexagon is 0.600 inches which is 5/16 Whitworth spanner size

I'll probably never learn

The 18,4 mm is the drilling dept by the way, what would that be in inches?

Hi Henk, Multiply the size in MM by 39.42 to give you the size in thousanths of an inch...18.4 x 39.42 = .725"....The inch is divided into 1000s, 100, 10s ...just like metric! It only gets complicated when you express it as a fraction...ie 1/16" = .0625..Ian

Hi Ian,

Thanks for the leason, that makes it a lot easier for me. So for the thread I should have put 0,3125 instead of 5/16?

I'll never learn

Hi Henk..This could get more involved!! To make it easy for you to convert from metric to Imperial the best thing is to use that formula (x 39.42)...and that would be 0.3125". For sizes over 1" it would then be, for example.. 1.3125"..2.3125" etc. It would then be easy for anyone conversant with the Imperial system to convert that figure to a fraction (5/16"). In (Imperial) engineering the standard practice is to express thread size as a fraction, so 5/16 would be the correct way but is more difficult to work out for all sizes. I'll send you a conversion chart..Of course there is always an exception...BA threads are not expressed by size but by number!!....Ian

Hi
Does anyone have this part or can make it as I need one.

Hi Folks
I would purchase 2 if anyone is making any. Is Rob's part number correct or is it 65-6794? I could also use one of the similar spacers (1/2 inch)for the front mudguard.
Best wishes

Ian should there be smoke coming out of my calculator when I do your calculations wouldn't Russell have any

Why Decimalize everything?? that is so typical US!!

Could not do without the fractions!!! just old fashioned I guess???

1 inch is 25,4mm that's what I use.

Cheers,

Lex, my guess is that micrometers and vernier calipers aren't calibrated in fractions, and Robb is planning to make the parts on a lathe. Unless you're using basic rulers and measuring tapes.....

The Imperial measuring system is marvellous....The history of it and the level of complication and non standardisation can provide hours of fun for the inquisitive...much better than dull old 'Metric'...European Metric that is, not the British version.(we do have our own you know)..... ...Ian
