A simple tip to avoid this in future is to turn bolts anti clockwise (assuming standard right hand thread) with a driver (not your fingers) until you feel a click. This is the sound/feel of the starting threads matching up. Then turn it clockwise to tighten. If you are not sure turn it anti clockwise again until you feel it again.
I used to be absolutely terrible at cross-threading until I figured that out for myself. It's a great tip to pass on... and I occasionally do also.
And clean the threads or even re thread the bolts with a die or run the correct size tap in holes before re installing ..................................................
This I absolutely avoid doing unless the threads are damaged. (in which case, a re-tap likely won't hold the required torque) For me at least, the debris invariably results with tap seizing, then cross-threading. Even when it didn't end in a total disaster, some thread material still got needlessly removed. (so - pretty much always results with holding less torque)
, what I do is use a steel wire pipe cleaning brush. For example, a prior automobile's spark plugs had anti-seize on them. I'd always blow out the wells with 150 PSI compressed air *before* removing the spark plugs, but over the decades, sediment still managed to get trapped in the threads. I had one particular cylinder that just required too much torque to be comfortable. The other cylinders had some resistance, but nothing like this one. Got an idea! Went to Lowes, got a few diameter sizes of steel wire pipe cleaner brushes; maybe 1/2", 3/4", 1". Cylinder three not being at TDC, rammed the brush straight down the hole, then proceeded to back it out, by turning it counter-clockwise. It was so difficult to turn (because of the intentionally oversized diameter) that I had use pliers to turn it. By the time I was done, I could screw that spark plug in by hand as if the 20+ year old head were brand new.
BTW, I also hacksaw the handles off of these, put them into a drill, and use them to cleanup battery clamps and terminals. I also put them into high speed
A/C plug-in drills and use them to hone out caliper slide mounts. Everybody I consulted kept telling to replace my calipers because the caliper slide mounts chronically locked up. Honing them out with these steel wire pipe cleaner brushes was a permanent solution to the chronic issue... and I didn't have to replace my OEM calipers with aftermarket JUNK.
