You've got a few options. You can run over to Toyota and try to buy the bolts if they are still available(bring yer lube), or you can find someone will to sell their hardware off an extra engine on the forum here in the FS section, or you can carefully find the thread pitch and bolt size as well as eye balling the length so you can make a trip down to your local hardware store. I don't think I've bought an OEM bolt for years, however I am kind of a fastener nut(see what I did there). Buying universal hardware doesn't work for everything(camber bolts, banjo bolts, etc etc) however for your situation, no problems.

Most fasteners that I've seem in the 7M are either 6mm by 1mm thread or 8mm by 1.25mm thread. There are some notable exceptions like the head bolts (12mm by 1.25mm) or the timing belt tensioner, but those 2 threads will do most of what you need. Of course the necessary length of various things is quite variable.

The problem with generic for the 8mm threads is that they will have a 13mm head on them instead of the 12mm that Toyota would have put on. Not likely to be a problem, but it will mean a change in your common toolbox sockets next time.

Allen bolts are garbage. I used that set to replace the philips valve cover bolts on my car that were mostly stripped out. Gotta be careful not to overtighten them, but it's easier to get the torque right with a hex cap screw vs. philips
