Screw posts, also known as Chicago screws or book binding posts, are extremely versatile binders that allow loose documents of practically any shape or size to be securely bound together.
Barrel Nuts provide an alternative method for combining two pieces of material instead of using a traditional screw and nut. These fasteners go by various names such as inter screws, sleeve nuts, female nuts, binding barrels, and sex bolts – featuring a drilled-out barrel with a threaded centre.
