Hi, you're confusing thread sizes with spanner sizes. Whitworth and BSF used to have the same head size but BSF head sizes were reduced during the war to save metal. AF is the head size of UNF/UNC thread, i.e. 5/16" thread has 1/2" head size.

Colin

i understood that the head size & spanner length was designed to give the correct tightness before torque wrenches came into use, BSF being a finer thread than Whitworth, pulled up tighter for the same torque, therefore a smaller head was fitted so a shorter spanner was used. I'm not sure about the wartime thing, it goes back much further than that.

Hi, I thought it was further back in time as well, however I did check. -

M10 went from a 17 to 16mm head
M12 from 19 to 18

Hi, yes some Japanese motor manufacturers, Notably Mitsubishi, started that with a 14mm spanner size on an M10 fixing, but they did use a 'K' nut profile head to maintain head contact area.

Hi Colin, it looks to me that they reduced both types for the war spec, not just BSF. I've got spanners that go back to the year dot marked 1/4bsw/5/16 BSF. The explanation I gave was given to me by my father, he was an engineer prewar, (born 1908) the torque factor/spanner length makes sense, but so does the war spec. Maybe both are correct in the fact it was done before the war, but became official during the war for standardisation.

What's happening now , it's gone all quiet in here

just finishing the spread sheet as I am close to shipping first batches. I dont seem to have your name down were you interested??

OK I have a spread sheet of all those I think have order. Can you all check and confirm your order.

What would be useful and fair to the forum is if you can PM me . Anyone who has asked for special packs (thankfully there are not many of you) I will sort out IF POSSIBLE.


I have approx 40 packs almost finished. I have been bagging up a sack at a time and now all that remains is to pick and pack them.

I will be using UPS access point to access point which costs £7.14 . This is not an insured service so if you do wish to insure against loss it will cost and extra £1.20.

I did offer to send them for £25 for a 20kg package. so its down to the individual what you wish to pay.

I will speak to UPS and see if I can get any discount and the same for pacel2go but I doubt it...

IF anyone wants then delivered to their house instead of collecting from an access point it will be £8.39 plus £1.20 insurance.

ANy questions just ask.

Looks good, mate - thanks! Let us know when you're ready for paypal details

Cracking job. But can you let me know the length of the M6 bolts. They are going to be used balancing fans and if they are too long they look crap, catch product and are dangerous

You can easily make a too-long bolt shorter. Not so easy to do the reverse

Chopping down a kilo of bolts does sound like my idea of a good time.

Have you got children?

If so, you could have a 'fun weekend planned'...
Cost? A hacksaw for each, and some spare blades!

 

[JEZGUZ]

As I'm going to see a mate who owns a pub just inside Wales tomorrow, is it possible to drop by on the way and pick up the bolts?

Ah - fair enough - I thought you were talking about needing half a dozen or so. No - doing the full bag wouldn't be any fun!

Yes mate I think there are various lengths of 6mm bolts but I need to concentrate on the main standard packages for now as all my own money is tied up in them. I will get round to more specific quesries when I can actually move in the back room. I hope you understand how manic it is in there just now..

Yes mate that would be fine. You can then let people on the forum know what you think of the package

I want to be accurate and 100% I am in a position to ship within 3 days of payment if possible....this has taken far far longer than imagined...lol
