Plastic screw posts are molded Delrin and Polyethelene posts having a large head at one end and a hole at the other. A large-headed screw snaps into the hole on the post, allowing for rapid assembly. Plastic screw posts may be easily unscrewed to remove or add pages.
The post length is 1/4" and the diameter is 0.24". The post length is the maximum binding thickness (inside length). We recommend that you measure your document to obtain the best fit. These screw posts will fit nicely in an industry standard 1/4" or 5/16" punched or drilled hole.
If you need greater strength, we recommend our industry standard aluminum screw posts. For even greater strength to hold large or heavy materials, please consider our steel screw posts.
