600 miles on those PR4's.Depending on your speed and lean angle...yes...they can 'lightly' move off track occassionally.They won't keep doing that though.

No. It's the friction between the threads that tighten and hold the bolt. That's why a bolt with bad or chewed threads feels tight.

That statement is incorrect.

The friction from the threads, is what can give you incorrect torque settings when
trying to properly torque/preload a bolt and will lead to incorrect clamping force
on your joint.

Because of the friction of the threads it becomes hard to correctly torque(set preload) a set
of bolts to the same clamp force causing varying clamping loads on your joints.

The only way a bolt creates the proper clamping load is by stretching the bolt itself.
That's why a bolt length gauge is the #1 one way to set the clamping force of a bolt.
The #2 way is using a torque wrench, but a torque wrench can lead to improper clamping
loads due mostly to thread friction.

It's the spring action of the bolt that causes the clamping force.

Would a bolt made from tungsten carbide tighten?

I'll guess no, because tungsten carbide is so hard that it will not stretch properly.
Did I get it right?

Ductility.

Yeah well I do not believe in tq wrenches but I do keep a full set of heli-coils in SAE and metric on hand for them weak threaded holes.

for them weak threaded holes.

If only they made them for women that had >/= 5 kids.

They have vaginal rejuvenation surgery for that--if you can find a woman who wants to start all over. good luck.

So 4 kids she gewt tuh go

Essentially, that depends on your thread diamwter but there can be a lot of leeway based on personal preference.

I think most women would prefer to tap a larger thread diameter if the job is half done already.

Just make a sleeve for it that is small on the inside and bigums on the outside. They make this stuff called "Cooter-Lok" that keeps the sleeve from falling out.............
