Anyone know a cheaper alternative to Tamiya, 5X8mm Hex Head Ball Connector ,(53969) that have the same size and hex head?

I was thinking of those for my M-05R since the short originals break inside the aluminum steering parts, so it's a pain to remove them as I seem to break them frequently. That longer one would allow screwing far enough through the aluminum to allow securing it with a nut (which in turn would be threadlocked) and in case of breaking it'd be easy enough to remove. Also would do away with the problem of the connectors coming loose, because I currently don't threadlock them due to making it even harder to remove if they snap (I know they can be heated to melt the threadlocker, but still a pain). And also the hex head makes them easier to use that the stock balls.

I guess I'm just being a cheapskate but ~$10 with shipping is a bit meh for 5, and that'd only leave 1 spare for front steering so would probably need two sets anyway. Everything else with enough length and a hex head seems to be 4.8mm for the ball, which would supposedly be slightly too loose.
