Product specifications of our binding screws and accessories
You can read more about the materials, dimensions and applications of our book screws in the product specifications:
Metal binding screws are supplied in three standard finishes: nickel-plated, brass-plated and black zinc-plated. Other colours are available if required. Book screws can be supplied with coloured heads, on request.
Plastic binding screws are available as standard in black and white. They are also available in other colours, on request.
Capacity and sizes
Binding screws can be used for creating books from 2 to 150 mm in depth. If you make use of a longer tube, you can use extension pieces to allow a capacity of up to 150 mm.
The standard metal and plastic tubes are 5 mm in diameter, so the holes drilled need to be at least 5 mm in diameter. Plastic binding screws with holes are actually 6 mm in diameter.
All the accessories for binding screws can be used with our metal or plastic M4 book binding screws. Only the extensions cannot be used with our plastic binding screws.
Book screws are ideal for creating colour sample charts, swatch samples and menus.
The metal items in this web shop are intended for use indoors. If you intend to use the items outside, please get in touch with us to find out what options we can offer.
Binding screws are threaded and can be unscrewed. So it is possible to open up your catalogue or swatch book repeatedly and add samples or remove samples before closing it again. The tubes and screws can be tightened by hand or with a screwdriver.
The metal hammer top screws are different; they are for one-off use and cannot be removed.
What makes this product unique?
Accurate to 1 mm.
With our extension pieces, it is possible to achieve accuracy to 1 mm. Our binding screws can be used for bundled samples ranging from 2 mm to 150 mm. When you make use of extension pieces, you can build even larger bundled samples.
Can be fitted just by hand
Both the metal and plastic book binding screws can be tightened by hand or by using a screwdriver. So there is no need for any other equipment.
Can always be disassembled
The majority of our book screws are non-permanent. You can always unscrew your books and then refit the screws.
