screw sizes and different size wood

[james e thompson]

what screw would one use to fasten 1" wood to 2" wood?

[Brian Rogers]

I would probably go with the 1.5"

James,

For this application you will want to set everything up for 1" and then use your 1 1/2" screw.  If you have any other questions please let us know.

I have been pondering on this for a while now.....actually got into a short discussion about the HD, now I have been told it will be good enough to use my standard Kreg Jig. Now the question is what size screws. I am attaching 5/4 soft maple to 5 1/2" table legs,also soft maple. These will be the top rails on an open table, almost like a work table, that is housing a counter top that weighs approximately 90 lbs. There will also be a 6 burner gas stove mounted in the counter top. The counter top is 2" douglas fir and is actually some sort of self supporting flooring that my boss was given. I am planning to go into the legs as well as the counter top.Suggestions? I know it needs to be something bigger than the 1 1/2" screws that I use to put cornhole boards together.....LOL.

Tim,

for attaching 5/4 soft maple to 5 1/2" table legs,

I'd use the 2-1/2" long screws.

I want deep penetration of the screw that goes into the base material, I'm attaching the member to, thus the reason for the 2-1/2" screws.

I saw a video somewhere about this very question.  It showed how to join two different thicknesses of wood and how to decide what screw you needed.  I have searched online for it and cannot find it.  Does anyone know where that is?

I'm using the Kreg jig and fastening two 3/4" red oak boards to make a table top.  I assume I will need a fine thread screw but I'm unsure on the screw size.  Can someone help me one please?  Thanks for your time.

I too was unsure of screw sizing! So I bought a Kreg Screw Chart (wheel) on E-bay for around $10. Now I can find it fast!
