Screw Post FAQs

What are screw posts? A screw post is a two-piece binding screw that is placed through a hole, and then screwed together to hold the pages bound together. One of the screw ends (female) is a post with a hole, and the other (male) is a post with screw threading. The threaded screw holds tight into the corresponding threaded post.

What kinds of screw posts are there? When it comes to binding, screw posts are available in several different material options. Standard aluminum is the most popular, and has the widest range of sizes and colors to choose from. Aluminum screw posts are strong and sturdy, while still being very affordable. We also offer steel screw posts that are stronger than any other option if you need an extra heavy duty choice. In addition, there are plastic screw posts. Some are made for binding just a few pages (called push lock posts)
