So I need some bolts for a Kango as someone borrowed it and some vibrated loose and have gone missing and the few that were left, I THINK were overtightened and the shock of the Kango sheered them.
There's 8 fairly long M4/M5 bolts. What sorta tensile and type of bolt do we think they should be?
They are holding the base of the hammer against the chisle so do take a bollocking.
No idea what to order and Kango have been bought out and I can't find the correct spares!
Cheers. :)

Possibly unbrako, with threadlock or spring washers. Got a photo?
-
Oh and this is a good thread :grin: teehee :embarassed:

No photo but basically like this:

No washers.
Just don't want to put weak bolts in it and it break on site as it did yesterday and had to go hire one!
-
If you can't find a spec, you could get some high tensile ones, probably fixed with threadlock if there's no washers, as something's got to stop them from shaking lose.
-
It should say on the head of the bolt what thread and tensile they are, it'll a tensile strength of 8.8, 10.9 or 12.9, and the thread will most likely be a medium thread 1.25, it could be fine 1.0 or course 1.5, but I'd say it is most likely to be medium.
I'd just put 12.9 in as they are the strongest, so I'd say 12.9 1.25, if you have a bolt just take it to a good hardware place and ask them to tell you what it is, even if they don't have them they should be able to tell you where to get them

^^^ Is the right answer. 12.9 are the highest spec for tensile strength. Unbrako are a reputable make so these are preferred but don't get hung up on that make if you can't get them - any 12.9 bolt should have a strength of 1200 MPa.
For shock loading, bolts loose 50% of their strength over a million cycles. On a Kango this could be just days or weeks.
Having learned the hard way - and for complicated reasons - they last much better if they are torqued up correctly.
LOL - does that qualify me as a bolt geek?

on old bexley lane just off the junction for dartford on the a2 there is an entire shop dedicated to nuts and bolts. you'll get all you need from there.

Cheers guys will get some from a local shop in Dartford.

I think NASA may have some spare, they are the same as Space Shuttle tile fixings bolts... so will be fine :grin:

I've got a bolt collection have every bloody bolt, rusty, smelly, green, funky, disco, short, hairy :grin:
Anyone wanna see my bolt collection I have two collections Good and Rusty can provide pictures for the mentally bored on here :drool:

Its possible to get your thread crossed with the nonsense going on :huh:

This goes out for Sam who hates bolts :grin:
Thom becarefull what you ask for :tongue:
Find and bolt and tel me where it goes!

These rant the three bolts that go through the gearbox mount are they?
we have had a kangoo sheer these over 4 times now.

Do you have solid mounts?

Bumper bolts and alternator tensioner bolt too (the one where the cog always strips)
-
jay, yours are far to neat, i just have a drawer to " store " fixings etc

The shiny one is smaller can't remeber what goes on that possible 8V the larger one 16v 90a alternator and yes they do strip quite easily Chris!

Nice! great minds hoard alike :grin:
I have a few more boxes don't want to seem greedy :laugh:
You got about £100 just sitting in the middle of that draw :lipsrsealed:

:grin: i know, might get a safety deposit box to put it in :laugh: that rare apparently :laugh:

Well you know going to shows these days people remove them before going and BBS caps :lipsrsealed: :sad:
I think the most useful ones are starter motor bolts and PAS ones I'm constantly surprised what VAG can charge just for rivits and bolts even rear speaker metal caps that go over the crappy hollow nuts :rolleyes:
