bahco adjustable spanner
I have a Bacho 8073 (not chinese copy which work in reverse and are a real pain in the backside) that has lost its bolt which holds the thumb thingy in situ. Does any member have one that can tell me thread size.
The thread is quite deep into the shifter and its impossible to measure...well i cant anyways.
They want a small fortune for a replacement.

Eskimo,
I have a couple of Bacho 0673 shifters that are 1967 models & they have a thread that measures Ø7.05mm OD x 0.95 pitch.
Hope this helps.
Don.

Firstly Bahco shifters don't work in reverse, they work the correct way and all the others are backwards I have heaps of Their shifters.
The 8073 is 7mm diameter, I don't have a pitch gauge and normally just check with another tap, the finest metric tap I have is 0.8 and it is finer than that. Measuring across 10 threads with the vernier I get 6.5mm, so 0.65 I would say.
Cheers Andrew

Andrew...I did say "Chinese copies"...
Picture below shows Bahco 8073 made in Sweden...top adjustable is also named Bahco not made anywhere as it doesnt say ...check the thumb screw against your made in Sweden Bacho's and you will see that its guide threads (if thats what they're called) are angled differently, and therefore must operate in reverse...I think I saw these reverse operating Bahco's when I was last in Total Tools

the white writing on the bottom one is what I thought it might be
Thanks Don and Andrew for those thread sizes

You can still use it for it's secondary purpose. A hammer.
Gold, the colour of choice for the discerning person.

So as they say you learn something everyday! I have had Bahco shifters for 30 years and have only just realised that they have screws that go opposite ways. However I also learned that it doesn't matter where they were made as I have made in Sweden ones going opposite directions.
The top 4 are all marked made in Sweden, the top 2 go one way, the next 2 the other. The bottom one is Bahco with no country of manufacture marked and goes the same way as the large Made in Sweden ones? So there you go.
I won't even start on my Bahco Multi grips with a shifter adjuster and which way they operate
Cheers Andrew

So what i thought was a chinese copy may not be a chinese copy then. Why would they do that...change screw so direction of sliding jaw works in reverse. Dont they understand how one gets used to the way things should work and expect all tools of same type to do exactly that....i hate it when they go the other way...even to the point that i gave away the ones i didnt want cos of this reason.

The .9 wouldnt go...
38tpi was the closest I could get to 0.65 and which I thought might "reform" to 0.65 and which it did...but to 0.75
we were somewhere near it..
the 38 will hold it for now...lol.
thanks Guys for your assistance.

bahco adjustable spanner
like AJ, I also have a large Bacho that adjusts one way and a small one that adjusts the other way. Is it possible there’s some logic to that we are missing?

More Confusion.
Ken's suggestion of handedness made me look for clues in the 1965 BAHCO catalogue I just happen to have. There is no mention of the left and right handed adjusting knurls but both are pictured. My oldest shifter is a 6" 970 with the marking " AB BAHCO STOCKHOLM ". It has a right hand knurl. Of the eight shifters in my collection, three are right handed.

Ken[/QUote
cant beat logic
So this begs the question: why do you only see one way from any one manufacturer in a store... all new Bahco's i see now are left and from Rothenbeger all will be right....in the same store...why dont you see both from same maker?
never seen a left Rothenberger...nor a sidchrome if i recall correctly....even my stainless steel NZ made Sea Spanner is right...also my trojan and other cheapie are right
Mmm came across a 450mm bahco made in sweden in my tool chest ...which is left...i give up.
