other faster simpler cheaper approaches welcome


Attach nut, cut off bolt so it sticks out 1/8 inch or so, peen the end
of the bolt.

Apply epoxy to bolt, install nut.

Salt the bolt, install nut, spray with salt water ;-)

Install bolt & nut, fire up welder, weld together.

Install bolt and nut, drill and pin.

Install bolt and nut leaving several inches of bolt sticking out. Bend
over bolt with sledgehammer.
