Are the holes threaded so you can actually screw the bolt in?

This is a "drill bit gauge"-- it isn't for checking the diameter (or thread count) of a bolt. You are looking for a screw gauge.

Anyone know how thick thick this guage is?

1.2 mm or a little bit less than 1/16 inch.

will this help me determine which size drill bit to use if I have a screw or bolt? Or will it just tell me what size a drill bit is that I have?

Take the gauge and find the right drill bit for a clearance hole for the screw or bolt to fit through. If you want a hole to drill for an anchor hole, find the smallest hole on the gauge that the screw fits through, then go down two sizes under the size it fit through. That will allow the screw to have enough material to bite into. E.G. the screw fits through a 3/16" hole , then go to a 5/32" drill bit .Hope this helped, jeff_rsr.......

From the picture it looks like this just shows the metric diameter for the fractional inch holes but is not actually a metric gauge, correct?

It’s fractional measurements based off the inch or commonly referred to as sae. It shows the metric equivalent. So it’s not metric exactly.
