7075 alloy wheel nuts – Yamaha

Ridiculous! how can something so light be so strong? this morning i thought i’d test one to destruction, to put my mind at rest. i screwcut a piece of 20mm titanium bar 1.25mm pitch, made a nut to suit, put the bar in the vice and set about it with my heavy duty torque wrench, at 70 ftlb i had to tighten the vice, at 100 ftlb i couldn’t get the vice any tighter and it was still pulling the titanium bar through it! i gave up as my neck veins were threatening to give way beforte the threads did!

My conclusion – 7075 alloy is tough! tough enough for all wheel nuts, all i’ve got to do now is be brave enough to start making spindles from it.
