Torque tech.

[AnthonyG]

I never thought about it much until recently stripping some hardware during torquing. I typically check Spec for limits & pattern if given to make sure nothing unique then torque everything 20% under spec, Using outside to middle pattern alternating opposite positions for first cycle. Then go back on 2nd cycle to max spec, Ie, 10-15 ‘lbs I go 15 as i remember reading many things can effect actual torque final as much as reducing by as much as 50%. Since for many years I adopted using max range as final. Always thought max on range better for not coming loose! As a result of recent event requiring disassembly, Fresh Flywheel, & balancing, I’ve rethought my technique & maybe using mid range to be a better idea? While it wasn’t the 1st time I stripped a thread, it was the first time it happened while using a torque wrench per spec. My technique has been more from habit from my youth although, the “Rules for torquing & the potential 50% reduction from various conditions I read years ago still sticks in the brain! The rest of my torquing Technique is probably from torquing Enough stuff & noticing the spec’s generally followed that pattern. I can’t really remember but obviously must have copied someone’s instruction in the beginning. Thoughts?
