Don't listen to that. For one thing, your ends gonna get chewed up. Ends are hardened steel, but that doesn't mean it's indestructible. It can get chewed by axle nuts and axle lock nuts which are as hard. More importantly, tightening the crap out of it, you might crack the axle lock nuts. That's gonna be a booboo to fix, because spares need to be ordered and stuff.
... I ought to know. I chewed up my ends.
... And destroyed my axle lock nuts. I had to replace em.
