What is the ideal screw length for assembling 2x4's at a right angle (90 degrees)?

2 1/2 is the right length . make sure to adjust your jig first.

will it fit a 3/8 inch pocket hole?

The Kreg SML-S250B-50 will work with the standard Kreg 3/8" pocket hole.

Are these authentic from Kreg? When I compare the packaging they look different.

I tried to use these to join 2x6 boards but the screw tip comes through the opposing side I have the bit collar set to the proper depth. Any ideas?

Are you setting the depth at the shoulder or at the tip? I set at the shoulder and it works for me. Try putting the jig at 1-1/2 inches and then putting the bit in the jig and setting the collar so the bit almost touches the base of the jig. The object is to have the bit exit the first piece of wood at the center of the wood (3/4" from each side for 1-1/2 inch 2*4) scott vmtwcom
