Aluminum Binder Posts (Chicago Screws or Screw Posts)

Aluminum binder posts or Chicago Screws, as they’re sometimes known, or screw posts, or threaded rivets, are handy substitutes for rivets.  We sell them in two sizes:

1/2 Inch: Head diameter of 7/16″, and that’s at both ends (the head and the screw-in piece). Use the 1/2″ size if the part you’re attaching, plus the thickness of the wood it’s going through, is somewhere
between 1/2″ and 3/4″.

1 Inch: Head diameter of 7/16″, and that’s at both ends (the head and the screw-in piece). Use the 1″ size if the part you’re attaching, plus the thickness of the wood it’s going through, is somewhere
between 1″ and 1-1/4″.

Just push the fat part of one of these into a drilled hole, put the screw in from the other side, and screw them together.  You’re done.  They draw down tight and hold well, and if you want to be sure they don’t loosen over time just put a drop of superglue in the threads just before you screw it together.
The post end is rounded/domed and smooth – it looks like a rivet head and nobody will know except you and us and we’re not talking. We use these as center pins through some heavier duty trunk handle brackets, and also to attach thick handles to heavy wood trunks.
