re: Metric vs imperial

Most machine manuals list screw sizes, thank God. I lost a screw that vibrated out of the head lock on my planer once. Found the manual, went to the hardware store and I was back in business in short order. Then, of course I found the original screw on the floor immediately after I put the new one in.

All the hardware stores have those nuts and bolts identifiers so if you have a broken piece of it, at least you can identify what it is and buy a replacement. A little tougher when you don’t have any spares to bring or a manual that identifies the size.
