Widely used in the production of goods with components made of synthetic materials such as ABS, plastic, thermosetting.
Plastic screws are fasteners specially designed to ensure a secure grip in thermoplastic and thermosetting materials, without the need for metal inserts or pre-existing threads.
They are particularly used in the electronics, household appliances, automotive, and technical equipment sectors.
Thanks to their wide thread pitch and special thread geometry, these screws are able to deform the plastic, creating a stable and resistant coupling without causing cracks in the material.
They are available in 30° or 45° thread versions, depending on the type of plastic (rigid or elastic).
The screws are available in different configurations to suit any application requirement:
Consult our technical catalog to identify the most suitable screw. For quotation requests, attach the code or technical specifications and send them to: info@milanoviti.it. Our technical team is available to assist you in choosing the ideal fastener.
Plastic screws are designed with a special thread, with a wide and deep pitch, to ensure a secure grip in plastic materials without causing cracks or damage. They often have a flat or blunt tip and require a pilot hole for installation.
Standard self-tapping screws are designed for sheet metal or thin metal and have an aggressive geometry for cutting metal.
Screws for plastic, on the other hand:
They are suitable for many thermoplastic and thermosetting polymers, including:
The most common configurations include:
With Phillips cross, Pozi cross, 6-lobe, cross screwdriver combi, 6-lobe screwdriver combi.
Yes. To ensure correct installation and prevent cracking, it is advisable to drill a pilot hole slightly smaller than the diameter of the thread.
The depth of the hole must cover at least 80–90% of the length of the screw.
The thread is deep, sharp, and wide-pitch, often with sharp edges to improve anchoring in plastic. Some models also include:
Plastic screws are generally manufactured in:
It is generally not recommended to reuse them, as the thread may no longer have sufficient grip after extraction. If necessary, the use of threaded inserts or reinforcement pins is recommended.
