hi, as a mechanic I can tell you 10nm is nothing, as a guide a jubilee clip should be around 7nm, the wheel nuts on your car would be anything from 80nm for a 10mm thread(17mm socket) to 130nm on a 14mm thread (22mm socket).
assuming that it a 3/8 ratchet in the previous photo then I could quite easily reach 40nm without using any weight on it (just using twisting motion of my wrist, not putting force in by being above it and pushing down if that makes sense)
hope this info helps
Phil
