BSF Wrenches/Sockets

[JackIIA]

Well, I'm breaking down and buying afew BSF sockets/wrenches to supplement my normal American/metric stuff.

Please correct if I'm wrong, but where I'm reading about Whitworth wrenches, sockets, etc., I can assume these are the same as BSF wrenches??

I know there is a difference between pitch of the thread and # of threads between Whitworth and BSF, but in terms of getting a grip on a bolt, the terms Whitworth and BSF are interchangable right? I read somewhere that the tool measurements refer to shank diameter not head of the bolt or nut.

FYI, pricing I've seen is about $80 for 7 piece wrench set and $60 for 11 piece socket sets.

This thread should be fun...

...get it? Thread?

I'll just post a conversion chart and let other explain the finer points of British engineering.

Whitworth explained a bit more.

Thanks 4Flat.

Article/conversion chart helpful. Particularly:


In effect, I believe that the only BSF/BSW sizes that you really need are: 1/8 BSW (3/16 BSF)
1/4 BSW (5/16 BSF) !

Looks like I should save my money and keep using a crescent wrench.

Of course if they are BSF/BSW then they are not wrenches, they are spanners

Putting it this way....

..after wrenching for 30 years....AND being a tool-a-holic who has to own the right stuff, I have never found a need for anything other than US or metric wrenches/sockets....

Ever.
