Plastic Snap Post FAQs

Q: Can they be screwed together?
While the screw end does feature threading, these binding posts are meant to be snapped together. The threading is not used for screwing in and, instead, is used as a securing method to keeps the pieces together.


Q: Can they pulled apart?
Snap lock screw posts are considered semi permanent because, once snapped together, they create a very tight bind. They can sometimes be pulled apart with great force and pliers, however, are not meant to be editable, so may need replacing if un-bound. If you need binding posts that can be edited, consider aluminum screw posts instead.

Snap Lock Screw Post + Plastic Chicago Screw Expert Review by Mallory Morsa


Plastic snap lock screw posts are a good option for semi-permanent binding requirements of small to medium-thick books, for users who need to bind quickly and without any equipment.

They are easy to apply, but very difficult to un-bind once snapped closed. This makes them ideal for permanent or semi-permanent bindings only. They come in three popular colors (clear, black, white), so you can choose the one that will best match your presentation. Black is bold, and looks great when paired with documents with photos on the cover, white blends fairly smoothly with white paper, so is not too intrusive on your design, while clear is the least noticeable way to bind.

They are available in several sizes to bind up to a 1” thick stack of materials. While this is not as thick a capacity as our aluminum or steel screw posts, this still offers enough versatility to bind thin and thick books in the most common range.

Plastic screw posts are also inexpensive, costing as little as about 13¢ each, depending on the size. We also offer bulk pricing for high quantity needs; all you need to do is call (866)537-2244. They are also versatile, requiring just a standard hole punch and no special binding equipment to use. This means you can completely customize how many screw posts you use to bind your document, as well as where on the sheets you bind. We offer 2 and 3 hole punches for some popular hole placement options.

As mentioned above, plastic snap lock posts are very hard to un-bind. It takes some strength and pliers to pull the two pieces apart, and sometimes they cannot be pulled apart at all, forcing you to unbind by actually cutting the paper off the post. This permanence can be a good feature for some, but bad for others…it just depends on the specific application and means that your pages need to be finalized and perfect before you bind. So keep this in mind before you buy plastic screw posts online, and consider the aluminum screw posts if you want something editable.

These are called “snap lock” screw posts because, although they do feature the threading making them capable of being screwed together, they are most commonly used by (you guessed it) snapping the two pieces together. This is because the threading is only on the screw end (not the post) and is there to create a strong, locking bind. This does confuse some people who want to be able to screw them together…so if you need something editable that is screwed (not snapped) closed, then you should consider those aluminum Chicago screws instead. It also takes some finger strength to be able to bind several in a row; and my hands were hurting a bit after testing many, which is not something I experienced with the metal posts.

You should also keep in mind that the smallest 1/8” screw posts do not have slotting on the post end, but instead, a hole. This allows the screw end to get deeper into the post for a stronger, more stable bind. All the other sizes are slotted. They also cannot be extended…so if you buy a 1” plastic screw post, you cannot expand the capacity later (which you can do with the aluminum ones).

Plastic screw posts are not my personal favorite for the simple reason that it hurts to press multiple ones together, however, they certainly have their place in the screw post binding industry. Even though they are plastic, they are very strong and rigid, they bind semi-permanently to prevent tampering, and they come in black, white, or clear to allow for a bit of coordinating. They are versatile, and only require a simple hole punch to create the hole for binding. If you’re still not sure these plastic screws are right for you, call us at (866)537-2244 or fill out a sample request form to test the item before you buy.
