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.

I recall AlumaTap when I worked in machine shops. If you used Tap Free on Aluminum it would turn it black. Back in the day. Now they have tapping fluids that claim to work on all metals. Tap Majic.

Beam type wrenches work well for head bolts but when trying to torque a bolt in a tight place you can't get a view of the reading. To view the scale properly you need to view the scale from straight above it, not on an angle.

Tap Magic doesn't work very on aluminum. I have tried it then my machinist suggest the alcohol.

That is what happens when they make a product that accommodates too many options. Too many compromises. It does not work well at anything while claiming it can do everything.

A lot of the products out there makes a lot of promises with few realized. I got some Free All penetrating oil that failed on every stuck fastener. A total waste of my funds when a 50/50 Acetone and transmission mix beats it hands down.
