Tiger suspension bolts
I have just nipped up all bolts on my avons suspension... the 2.5 inch bolts will not give me 3 exposed threads past the end of the nyloc nut. Has
anyone else had this prob? The bolts came with the kit. Think I might have to get 70mm long ones instead?

fristly, how nipped up is nipped up? i thought i had mine tight, but torqued them to 65Nm, and still got a reasonable amount more out of them.
even then, my bolts were still about half a thread short, but it wasn't checked at the sva. that doesn't mean it won't be, but i
wouldn't worry too much, as long as a decent amount of thread is sticking through the nylon.

This 3 thread "rule" always puzzles me. Im a time served engineer and have always wondered how the nut knows how many threads are sticking
through??
imho, 1 thread thro and i would be cautious (due to tapers etc etc), 2 threads thro and i'd be happy.
Iam sure the 3 thread 'rule' applies more to the use of plain nuts and lock washers. Most OEM's use bugger nuts which are not as
thick as nylocs. If you are concerned about a nut coming loose then mark them up with a line of paint and keep an eye on them during routine
maintenance checks. Im sure the use of paint would please Mr SVA as this is std race car practice (as long as the paint doesnt show they have
moved!!).

i work in the aircraft industry and we use nylocs .as far as i know you only need one thread through a self locking nut such as a nyloc.

It's too easy to get hung up on this sort of thing - I like to see at least one non-tapered thread through the nut (the first thread is
usually tapered a bit, sometimes the second as well). After that, the number of threads is irrelevant.

Agree with Dave -
although will say that when working on military helicopters we HAD to have a min of 3 threads showing or aircraft was unserviceable to fly....
Aircraft are always over engineered and overly cautious so maybe that is where this thing about 3 threads has come from ?

If it helps
I have had to use just one washer - under the nut - and have barely got a single good thread showing. with a washer under the bolt head as well there
was no hope....

Dave, I have done the same with just one washer under the nut. Would have liked to put the same under the bolt too, but not enough length...

tightened mine up last night and struggled to even get one thread clear on some. I guess I will have to replace them with longer ones in the future
