Gents,

just bought a torque wrench which is 5-25Nm to check the torque needed to turn a shaft on a prototype. Under normal working conditions the shaft can be turned by hand, but sometimes one needs to press on the handle rather heavily to make it turn (variable levels of resistance). Currently I'm unable to use the newly bought tool as the wrench is 1/4" and the bolt on top of the shaft is M12 which means I need a 19mm socket and as it turns out a 1/4" 19mm is not available so I need a converter. I've ordered the right bits and I'm waiting for them to arrive, but in the mean time I wondered how much 5-25Nm is? one wrench size up, which is 3/8" (19mm sockets easily available) is 20-100Nm, but I've made a guess, maybe incorrectly, that this will be way above hand crank levels.

So to sum up, is 5-25Nm anywhere near hand crank / hand tightening or should I go for 20-100Nm instead? it's just that it's a bit hard imagining all these Nms.

Regards,
