It took a decent amount of patience and a LOT of force to get these guys pressed into place in order to replace my broken wheel studs. You have to stack up several washer with just the right ID (some that let the threads pass through on top and some that let the larger swage diameter through on the bottom), upper left pic. Then you have to tighten it enough to swage (smash) the splines into the axle hole (upper middle pic). I had to apply about 1,200 foot pounds of torque to make it work and that was after chasing the threads of the stud and lug nut with a tap and die AND lubricating them. Upper right pic shows one of the old studs where you can see how the splines smoosh down. Lower right shows a new stud, where it fits, and how it compares to an old stud already in pace.
To give you an idea of how much force 1,200 ft-lbs is… The lower left pic shows the first lug nut I tried it on. That little stip of metal that look like a wire is where the force was high enough that it pulled all the treads right out of the nut!
In the end, I got them all in place and didn’t break anything. It was a fun learning process really put my tools to the test too.
