What Is a Screw Post Binder?
What are Screw Posts?
Essentially a screw post binder consists of 3 elements (well, 4 of you include the contents). The first is a hollow metal tube that has a screw thread at either end. The second and third are screw caps that fit at either end of the tube.
The diameter of the tube is the same as a normal hole punch or that found in page protectors.
The tubes come in a wide variety of lengths from the very short of 5mm to 120mm. You can also get extension tubes as well.

How Do They Fit Into a Binder or Portfolio?
They are quite simple really, below is a series of photos using a hidden screw post, explaining how.
We are using the Hidden Screw Post Binder as an example, but the process will be similar across the range.
Having placed the spine cover over the posts (above) the next step it to simply place your pages or plastic page protectors through the posts (below)
At H&Co the distance we place the holes for the posts is based on standard hole punch distances. For an A4 landscape binder we use a 2 hole paper punch, for anything larger it is a 4 hole paper punch. For the United States sizes of 8.5 x 11" and 11" x 17" we use 3 hole punch distance.

What is the main feature of the screw post binding system?
A screw post binder works pretty much like a book in the way it is read. Unlike a ring binder or lever arch binder, the left hand edge of the pages are held firmly in place - just like a bound book.
The reader or viewer of the portfolio, is therefore not having to physically lift and manoeuvre the pages over the rings of the binder.
What are about for Photographic and Design Work?
Screw post mechanisms are as you can hopefully see above are quite easy and straight forward to use, but add a certain element of style and sophistication to a presentation.
How do I know what length posts to order?
What are Screw Post Binders NOT good for?
If you are regularly adding or taking pages out of a portfolio, then post lengths have to change, which limit you to just the Exposed Screw Post Portfolio as it does not have a fixed spine.
