Hello all!
I am looking for an unusual bolt size...
M12x1.25, 60mm-80mm long, case hardened, 10.9 for preference (though 8.8 at a push if needs be and there really is no other option). Cup point grub screw for preference, cap head for second, hex head if there's nothing else, must be threaded all the way down...
I cannot for the LIFE of me find something that fits!!!
I have tried:
Orbital Fasteners
Hague Fasteners (they can do them for me for £145 the pair)
Ebay
TR Fastenings
...and a whole bunch of other places online.
Anyone got any thoughts?

Yes it's a set screw I need, but I put "bolt" because most folk don't know the difference unless you explicitly point out a fully threaded shank vs part threaded. In any case, it is for an adjustable suspension setup on my Volksrod. Hague got back in touch and said they can tag my requirement of two bolts onto the back of an order going through for £100...  / Must be very expensive to make! |

Run a tap down a case hardened bolt? What kind of taps do you have? LOL
That said it's an 8.8, might get away with that, but the tapped area will be exactly where the load will be much of the time, not good. Will put a pin in that one for future use...

ones that are now a bit blunt :lol:
got an image of the application? it seems that 50mm is the longest you will get a fine threaded bolt/screw without having to have a shank.
I do have a wheel stud actually that is M12x1.25 but obviously wont have a head on it.

Longest I found is 50mm cap heads in various grades. It may have to do.

ahh, have you checked that an 80mm fastener will still be touching the arm? I have a feeling it will miss it.
would be far simpler to weld the threaded post further around, unless you still need full adjustment range back to standard height.

That's not mine, that's an example of one. Mine is a custom made job, about 40mm of the thread is taken by the threaded block. Mine pushes against a broader block but stays within a sensible angle so as not to snap the bolt (the load comes closer to the line of the bolt the more thread is wound through). |

Trouble is the cap heads are bolts and have a max thread of 35mm. Tried Spalding before. I think I'm going to have to rethink and maybe redo the spring plates in an M12 coarse. |
