Customized Stainless Steel 304 316 Non Standard Square Head Machine Screws
Description:
Sifang mechanical screw with insulation, non-magnetic, high-quality features such as corrosion resistance, beautiful, never rust, and modified engineering plastics, it can use strength, impact resistance and metal, we often say that the plastic screw commonly known as nylon screw after adding 30% glass fiber, its mechanical performance is much better than the ordinary nylon, plastic screw adopts the material of increasingly diverse, continuously improve performance, also more and more wide application field.
1. Medical equipment industry (insulation, no magnetism, environmental protection, anti-interference signal, making the use of medical machinery and equipment safer)
2. Wind power industry (isolation and insulation of PCB board of chassis circuit)
3. Aerospace industry (insulation and anti-interference number on electronic equipment)
4. Office equipment industry (never rust, beautiful and practical)
5. Petrochemical industry (high temperature resistance, chemical resistance, corrosion resistance, extend the service life of equipment)
6. Electronic industry (insulation, anti-interference, light weight)
7. Communication industry (insulation, non-magnetic, safety)
8, ship industry (acid and alkali resistance, corrosion resistance, extend service life) and so on...
The specifications and sizes of plastic screws meet the requirements of different occasions.
