Yes. My son has a craftsman and these are what he uses.

OLSON SAW FR49501 Pin End Scroll Saw Blade,18 Pack

Q: I am truly a beginner { wen 16" model #3920}. i am reading/video/hearing a lot on people calling the blades by numbers. #5 #7 #9 why?

The number refers to the thickness and width of the blade from front to back. The higher the number, the thicker and heavier the blade. A #9 blade, for instance is much thicker (and stronger) than a #4 blade. Thick, heavy blades typically cut faster and last longer than fine, precision blades cutting the same material. The drawback is that they cannot accomplish very tight curves well, and it is impossible to make a 180° turn without leaving a massive hole where you did it. A #3 or #4 can accomplish this easily, but if you try to cut a piece of 3/4" hardwood, they will last about 10 seconds before breaking! I hope this helps a bit. I've been scrolling for about 20 years off and on, and it's much easier to demonstrate this than to explain it without visual aids.

Q: will these work on an Delta 15" model 40 150 scroll saw?

I have not use it on DELTA but you can see the size of existing blade, if the size of existing blade is 5 inch then you can buy this and it should work on delta then. Apart from that, Delta should support Pin end blades. (which I am think it should)

Q: Will these blades work in a Delta 40-694 Scroll Saw?

I do not have that model scroll saw but the saw blades are standard pin end blades and if the Delta 40-694 takes pin end blades I would think that they would work.
