Titanium M6 waisted bolts
These are some tricky little M6 bolts with waisted shanks, the trickiness is not in machining the shanks but in holding them after to machine the heads. Normally I make the shanks just a thou or two under full diameter so they would be around 5.97mm with the thread diameter 5.85mm which means i can hold onto the shank without damaging the thread. But as these have a 5mm dia shank there’s nothing to hold without damage. So i made a holder for them.
