Lube head bolts?

Here is something to try next time that should work better than WD-40, its common 70% rubbing alcohol but I prefer the 90% version.

I do check mine with a digital torque adapter. That how found out how lousy HFT torque wrenches were. One was nearly double the torque setting before it clicked. No wonder I was snapping bolts

Also you should unload the torque wrenches when you not using them as leaving them loaded can cause the calibration to become un-calibrated.

Who calibrated your digital unit?

I never buy a clickable setting torque wrench. Like StarTech said, you must dial back to 0 when done. I just buy the old school beam style jobs that work for decades. Pick them up at garage sales or facetrash market place for cheap.
