I’m a bit old school and usually do bolts up by ‘feel’, but yesterday, a torque wrench saved me a lot of grief.
Some of the newer stuff out there requires a bit of ‘finesse’, because the bolts and castings are about as strong as plastic.
In other words, soft castings and even softer bolts are very easy to break.
This miserable little 5mm bolt held the KTM’s oil filter cover on. If you look carefully, the thread was starting to deform near the head of the bolt as I tightened it up.
It’s meant to be tightened up to 8nm, but it felt like it wanted to strip itself. That meant either the thread in engine casting was stuffed or the bolt was.
Fortunately, the bolt was stuffed and is easily replaced.
The worst case scenario is when it breaks in the engine casting, making it awkward to remove it.. luckily, that didn’t happen.

Good job. Torque wrenches can save the day. I use one to tighten the lug nuts on my wheels. That way if I get a flat tire somewhere, I’ll have an easier time getting them off.
