Hi!
I just found this quite useful info on properly mounting jfets (or other to-220 / to-247 etc. devices):
https://www.infineon.com/dgdl/Infineon-AN2013_12_Screw_Tightening_Torque-AN-v1.0-en.pdf
The recommendation is 0.6 - 1 Nm.
(hold ~60 - 100gr at 100cm distance, or ~6000 - 10000gr at 1cm distance)
If I understand it correctly, this is quite tight for a M3-thread, but not "as tight as I'd tighten the wheel-bolts of a car"...
