Screw posts, also known as Chicago screws or book binding posts, are extremely versatile binders that allow loose documents of practically any shape or size to be securely bound together. These low-cost, reusable Chicago screws enable you to easily change out bound documents, making them a great choice for price books, menus, swatch books, architectural and engineering drawings, and much more. TruBind's high quality, black-colored aluminum screw posts provide an easy-to-use alternative to other binding methods at an exceptionally low price point. Their two-piece construction allows for no-fuss updates, which is why they're an ideal choice for applications that require frequent updates. They are also easy to expand, with a number of screw post extensions readily available.

I used these to attach wood seat bottom to iron seat frame. The screws are very soft and you really can’t tighten them much without the slot for screwdriver stripping. For lighter application like binding photo albums may work fine

You can't go wrong with Chicago Screws of all different sizes. This size is only one of my favorite and I highly recommend them all.

Terrible.... first of all the screws didn’t come.... Probably because the seller didn’t use a bag instead just threw in what looks like a paper clip cardboard box. Which probably explains the five missing female ends. If that wasn’t the case the screws didn’t line up so you had to strip them almost and not joined like in the picture... do yourself a favor stay far away from this seller honestly a joke.... I honestly wouldn’t give a single star but one is required. I would send it back but nothing even worth the trouble after threading all the post and counting them... basically doing the seller’s job.

Three stars only as they appear matte black in the pic, but they are actually quite shiny.

Used these for setting tension on custom kydex forms.The local Ace sells bright colored versions for almost a dollar each, so ordering way more than I thought I needed at the time was not a problem.

Aluminum is extremely soft. Gently tightening the screws significantly dents them.
