Bad idea. Not enough thread engagement, too much stress
concentration.

The boat trailer sliders I've seen use U-bolts to clamp the slider
to the frame channels, and when they have it in the right position
they tighten the clamps and make a couple of tack-welds between each
end of the slide and the frame, so it doesn't move on it's own.
If they make changes to the boat and move the CG, you grind off the
tack-welds, loosen the U-bolts, and slide the axle as needed. They
are not meant to be easily field adjustable every time you reload.

If the "slider" is a channel, you COULD make it adjustable (fasten the
"slider" to the frame with clevis pins) so you could adjust the axle
position to balance different loads.

Please log in for more thread options That's how my utility trailer is build. When I bought it the axles
were too far forward. I moved them back and life is good. Mine has a
series of bolt holes so it only takes a few minutes to move it.
