Plastic Screws: Lightweight, Strong and Non-conductive
With one of the broadest portfolios of plastic screws globally, Bülte meets the needs of virtually any application. Below is an overview of selected plastic screws from our product range, highlighting their key properties and application areas.
With their hexagonal head, these screws can be tightened and loosened using a hexagonal key. The best-known is the fully threaded DIN 933 screw, also known as ISO 4017 under the ISO standard that replaces DIN 933. They are similar but the nominal size has been extended and the flats modified for diameters M10, M12, M14 and M22. The other well-known screw is the partially threaded DIN 931.
Available as standard from Bülte, these screws have a rounded or domed head. You can find them in our standard catalogue: DIN 84, DIN 85, DIN 34813, DIN 7985, DIN 404, etc.
These screws follow the shape of the support to which they are screwed, without being invisible. They provide greater strength to your assemblies. The Bülte catalogue includes the NFE 25-120 pan head screw and the classic flat head screw, available in several diameters.
They have a flat or domed head (with a choice of various shapes) and a slope under the head towards the thread, to make screwing easier, fit flush with the surface and allow better integration into the material.
These screws, which may be countersunk, have a rounded head with a clamping indentation to give your surface a neat and original finish.
Also known as plastic set screws, these headless screws have a flat or rounded end with a number of available marks. Grub screws are generally used to create invisible fixings or to hold components together. They are particularly suited to adjusting mechanisms, precision assemblies, tools, electronic equipment and other applications where discreet fastening is required.
Hexagon socket head screws, either fully or partially threaded, have a head with a hollow hexagon socket on the inside that is flush with the support, while providing a large contact surface with the support. The hollow hexagonal recess, which can be fixed with a hexagonal key (or Allen key), withstands a higher tightening torque and enables the screw to be fixed in a narrow space with little clearance.
Knurled screws are ideal for manual assembly, as they can be fixed and adjusted without tools. Thanks to different shapes of knurled heads, you will be able to find the right screw for your needs.
The T-shaped section at the end of the thumbscrew - also known as a butterfly or wing screw - provides a comfortable grip for the user, allowing quick and easy manual adjustment. This feature makes wing screws a popular choice for applications where frequent adjustment is required.
These thumbscrews, available with different types of fiddlehead, are particularly appreciated for their electrical insulation properties, making them a perfect alternative to metal screws.
These nylon screws - also known as star-head screws or wing screws - have a head designed with four notches or grooves. Ideal for manual assembly, these screws are lightweight, insulating and corrosion-resistant.
Binder posts, also known as Chicago screws, are designed to bind books, sample collections, menus, fans, etc. reliably and securely, while allowing easy opening for consulting or adding pages.
These screws, which combine plastic and metal, are designed to offer specific advantages in applications where metal and plastic materials need to be assembled safely and reliably. Robust and easy to use, these screws come in a range of heads for precise, solid manual assembly.
