I know it's not a shovel, had mine, worked on it all the time. Took road trips 70 on highways and shit started to fall off after an hour.
I use gobs of Red Loctite, for which I have an undying, morbid, fetishistic love, (I have never had stripped fastener threads or heads be they small or large due to its use. I don't overtorque fasteners), all-metal
locknuts, and lock washers everywhere I can fit them and I upgrade when practical whenever I replace stock hardware.
I figure they paint fire trucks red because a firehose is the best way to apply Loctite.
What doesn't get red threadlocker gets anti-seized since corrosion, especially between steel and aluminum, DOES strip fasteners and I despise removing a bolt with an "aluminum heli-coil" wrapped around it. Anti-seize is your friend when you take things apart many years later.
You can get locktabs for your exhaust pipes or drill the fasteners for aircraft safety wire. I haven't bothered as locknuts work for me.
I do this on everything I own, Shovels, Evos, trucks, my riding mower, whatever. It's paid off for decades. I'm lazy and revile anything that causes extra work.
BTW safety wire is used in aviation because it's highly reliable and a proper job looks pretty (safety wire doesn't rust) so if you want to explore that have at it.
