I am getting ready to make a tote for an old Millers Falls #140 jack plane. I am making the tote a little higher than the original to fit my hand, so I need a longer screw. The existing screw, best I can tell, is a 12-24.

The problem is that #12 screws are uncommon. I googled and found one site that has them up to 3”, and I need one about 4 1/2”. I could get by with a 4”, by playing with the tote height, and recessing the top hole.

Anybody know of a source?

Medicken, thanks for your reply. McMaster Carr does have a 12-24 4”long, but it is a flathead. If I can’t find one anywhere else, it is at least a fallback option.

Anybody else? I really need a round head.

Try your local Ace Hardware. When I was in college, I worked in 2 different Ace stores, and both of them carried the full line of Hillman fasteners, including 12-24 flat, and pan head screws. I believe the last one I worked at had them as long as 4”, 4.5” is going to be hard to get. You may have to special order a box to get them. And then what are you going to do with the other 49 screws?

Why not drill / tap for 1/4-20 which is MUCH more common?
