Removable aluminum fasteners for photo albums, sample books, swatch books, architectural and engineering drawings, menus or any application where loose sheets need to be kept together. These aluminum screw binding posts are sometimes called Chicago screws or Chicago screw posts, they consist of two pieces (screw and post) and are designed to be inserted into round hole punched paper and covers. For maximum strength, the post should be long enough to go all the way through all of the pieces when they are assembled. Making the hole a snug fit for the parts will also increase the strength of the connection. These posts are perfect for binding large documents and can be combined with aluminum screwpost extensions to achieve almost any size you might need.
* The diameter of these posts is 3/16" and they are designed for use with a 1/4" hole that can be either punched or drilled into your documents to accept these posts.
* The post length for these screw posts is 4". This means that the maximum binding thickness for these screw posts is 4". For best results and to ensure a correct fit, please measure your document thickness and ensure that it will fit.
* The heads of the posts and the screws are 7/16" in diameter to ensure a good fit with 1/4" holes.
* These aluminum screw posts are packaged 100 sets per box
