I use the LPO .092" stainless screw eyes or make my own screw eyes from stainless lock/safety wire from Malin or US Wire purchased on Amazon. If there will be 2 screw eyes or the bait is under 2 oz, I go will with .051" twist wire. If it will be a heavier bait with one twist screw eye, I go with .062" twist wire eye.

On small baits if I am using the LPO screws, I use the .072" stainless screw eyes and the 1.5mm rods, .062" shaft wire, or cut section of a nail for the pins.
Those 2 mm stainless rods are very hard. I use a hack saw and vice to cut them to length. I file the ends smooth before installing them in the bait. Using a Dremel on these can be very dangerous. Cut off disks have a tendency to explode on those rods.
