5nM is approximately 45 in/lbs (inch pounds) or 3 ft/lb (foot pounds). VERY LITTLE TORQUE!
How much torque does a 10nM screw need?
Very few bolts need torque of 50+ Nm and most of screws will fall under 10Nm. Arguably it is also easier to over torque smaller (needing less torque) screws than bigger ones.There are few sub 10Nm choices (eg: IceToolz Ocarina) and some sub 25Nm options.
How much weight do you need to tighten 5 nm of torque?
