2-1/2" aluminum screw posts are designed to bind large books. When binding any large document, it's a good idea to use posts that are a bit longer than necessary. The screws hold better when they are tightened down all the way against the post, and the book will be easier to read if the pages can move a bit. The posts can be extended to almost any length with our screw post extensions.

We sell screws and posts together so that you you don't have to worry about matching the correct parts. We also sell extra screws on this site.

Technical Specifications:

  • These posts are the industry standard size. They are compatible with all standard posts, including those sold under the Charles Leonard brand.
  • The post length is 2-1/2" and the diameter is 3/16". The post length is the maximum binding thickness (inside length.) We recommend that you measure the total thickness of the materials that you are binding to obtain the best fit. We also recommend that you punch or drill a 1/4" hole in your documents to accept these posts.
  • Posts are 3/16" diameter. The overall length of a post with the screw installed is approximately 2-5/8".
  • Post and screw heads are 7/16" diameter and 1/16" thick. The screw thread is #8-32.
  • 3/8" long screws are furnished with all posts.
  • Quantity per package is 100 for all aluminum screw posts. We can supply larger quantities on request. Please call for a quote on orders of 25 or more packages.
  • These screw posts can be extended using our 1/2", 3/4", and 1" screw post extensions. 1/4" screw post extensions may also be used with the addition of 3/16" screws (the 3/8" screws furnished with these screw posts are too long to work properly with 1/4" screw post extensions.

If you would like to have a different appearance, try our plastic screw posts. If you need greater strength to hold large or heavy materials, please consider our steel screw posts.
