Binding screws – What are the sizes?
Metal binding screw sizes differ from the plastic ones. The latter are available as sets in fixed sizes. Metal tubes and screws are separately available and in more combinations so that any capacity can be achieved.
Metal tubes and screws
Metal binding screws are available as separate tubes and screws or hammertop screws. You can choose your ideal combination yourself. This way, the exact right size can be reached by for example using our patented hammertop screw or extension screws.
Metal tubes are available with a capacity of 2 mm to 150 mm. The head diameter is always 10 mm, the tube Ø is 5 mm and the thread is suitable for M4 screws.
The metal screws with a M4 thread also have a head diameter of 10 mm. The following sizes are available:
- Screw M4 x 4 mm
- Screw M4 x 7.5 mm
- Screw M4 x 7.5 mm with 1, 2, 3, or 4 mm extension directly underneath the head
- Hammertop screw M4 x 9 mm
- Hammertop screw M4 x 9 mm with 1, 2, 3, or 4 mm extension directly underneath the head
Metal binding screws are also available in M6. In this case, the shaft has a diameter of 7.6 mm and the head Ø is 13 mm. For lengths and models please contact us.
Plastic binding screws
Plastic screws are available as a set with a capacity varying from 3.5 mm to 90 mm. The tube and screw heads both have a diameter of 12 mm. These high quality plastic binding screws are very strong and slightly elastic.
A plastic binding screw with hole through the length for the purpose of a ball chain is also available. This binding screw exists in a length varying from 3.5 mm to 50 mm. An overview of all plastic binding screws can be found in the webshop.
Book screws – Which materials exist?
Binding screws are available in metal and plastic models. Both are very strong and durable, but plastic binding screws are generally slightly easier to assemble than the metal type. Other than that, your choice will depend on the desired appearance for your application.
The following metal plating are available:
- Nickel plated
- Brass plated
- Black zinc plated
On demand, these are available with a head lacquered in any RAL colour. Please contact us for amounts and prizes.
From stock, the plastic book screws are available in black or white. For other colours please inquire about the possibilities. Plastic binding screws with hole are also available in both black and white. Please take a look in our webshop for a complete overview.
Binding screws – Usage & Assembly
Book screws are mostly used to bundle swatches, fans, colour cards or other samples. They can easily be (dis)assembled which allows for a changing content. Would you like to hang a swatch?
This is possible by means of hangers for binding screws or plastic binding screws with hole through the length of the tube. You could easily lead a ball chain through this type of binding screw.
Please note that not all tubes and screws match each other. Tubes until 7 mm can only be combined with the 4 mm screws. Tubes from 8 mm onwards can be combined with the 7.5 mm screw. Hammertop screws are only available in combination with the 10 mm tubes.
