I have had that happen, things go fine (or time goes by) and I forget. annoying

You should change the tile. Its the front action screw not the front bolt.

I was dreading to see the bolt had failed at the front lugs or some such.

I don't want to be mistaken for Mr. G, but screws, bolts are different things by common usage.

Technically its a threaded fastener, bolts would be cap screws.

Generally we think of screws as having a slot, hex drive (etc) and tending to under 1/4 inch but not a hex cap head.

Yes there are some cap screws that are really large torx head or smaller 12 point drive heads.
