100 nm without a torque wrench

that would be way too much torque; 100kgf = 980Newtons (x1metre) = 980Nm of torque

I have an 18" norbar torque wrench and it's pretty much that with my full applied arm effort (weedy southern nancy)

Ah, now *that's* a useful reply :thumbup

It's been a very long since I did physics, but you've reminded me how to figure it out.

I've got a socket wrench which is about 20cm long, so if I needed to apply 10kg on a 1m wrench then that would be 50kg on a 20cm wrench, ie pushing down with most of my weight would do it.

Thanks!

That suits me; I'm a Design&Tech teacher and in september i'm also teaching science, so at least i'm explaining things correctly.....
