When you guys do a big job and finally get everything back together....

Osmosis.

Put them in the glovebox and the car will absorb what it needs.

Those are just gifts from the bolt fairy.

Cute. real cute.

Into the oil pan where all the spare parts go? Duh?

I keep all the hardware in one place and expect to use it all during reassembly. In cases like swapping manifolds while I R&R a motor with a junkyard motor, I try to toss the second set of hardware aside and pay extra attention as I assemble and install.

Except on fridays.

Reengineering...they thought it needed 4 bolts but it really only needs three!

It's called weight reduction lol

No honestly I try to look to see if can find what I missed. Otherwise they get tossed into a bucket if its things that needed to be removed or is an item that is not needed on the vehicle.

They go into the can, might come in handy later.

Celebrate that I once again beat the engineers at their own game.

dont worry about it unless they're clearly high tensile load bearing bolts - that's when the panic starts.

then they just go in to spares for when we run out on another car.

but really this shouldnt happen. you keep bags and group your bolts/fasteners for a reason.

Usually try to separate bolts in individual bags and maybe take pictures if needed. Anyway most of the time, manufactures will use obvious size difference to make it easier to figure out.

Otherwise I have a can for each equipment I work on (outboard, atv, dirtbike, car, etc). I don't like mixing my mechanical bolts with my garbage imperial stuff.

We call them racing parts. Car is lighter, now it goes faster.

I'm so good at reassembling things, usually by the fourth time I can build a second one.

Hide them

Throw them away. I've obviously re-engineered the thing so that it requires fewer parts.

What? You guys don’t eat them?

Weight reduction.

That has happened a few times....but they were bolts that weren't critical...like those keeping rotors on (hondas)
