Product Description : PA66 + 50% glass fiber is a type of thermoplastic resin. Generally, it is synthesized through the polycondensation of adipic acid and hexamethylenediamine, and glass fiber is commonly used as a reinforcing material for it.

In the field of industrial fastening, PA66 + 50% glass fiber nylon cross recessed pan head machine screws have become a high-quality choice that balances strength, weather resistance, and convenience, thanks to their unique material formula and structural design. PA66 nylon itself possesses excellent toughness and corrosion resistance; after adding 50% glass fiber, its mechanical strength, high-temperature resistance, and deformation resistance are significantly enhanced. Combined with the classic structure of cross recess and pan head, these screws exhibit outstanding adaptability in fields such as electronics and electrical appliances, automobile manufacturing, smart homes, and outdoor equipment, providing reliable fastening guarantees for the stable operation of various devices.

The electronics and electrical industry has strict requirements for the precision, insulation, and temperature resistance of components, and PA66 + 50% glass fiber nylon cross recessed pan head machine screws perfectly meet these needs. Inside household appliances like air conditioners, washing machines, and microwave ovens, these screws can be used to fix motor brackets, control panels, and heat dissipation components. The PA66 material with added glass fiber can withstand the high temperatures generated during equipment operation, preventing component loosening caused by screw deformation due to heat; its insulating property can block current conduction, eliminating the risk of short circuits and ensuring electrical safety. The cross recess design facilitates quick tightening by automated equipment, adapting to the high-efficiency assembly needs of the electronics and electrical industry; meanwhile, the pan head structure fits smoothly with the component surface, avoiding wire or component scratches by sharp edges and reducing the occupation of internal space in equipment, which is suitable for the compact internal structure of electrical appliances. In addition, these screws are moisture-resistant and non-aging; even in the humid working environment of washing machines, they can maintain fastening performance for a long time, extending the service life of electrical appliances.

The automobile manufacturing industry has extremely high requirements for the strength and vibration resistance of components. After performance optimization, PA66 + 50% glass fiber nylon cross recessed pan head machine screws have become an ideal fastening choice for automotive interior parts and engine peripheral components. In automotive interiors, such as the fixation of center console decorative panels and door storage compartments, the high-strength characteristic of these screws can resist continuous vibration during vehicle operation, preventing component loosening and abnormal noise; the pan head structure fits flatly with the interior surface without affecting the aesthetic appearance of the interior. Inside the engine compartment, their high-temperature resistance can adapt to the high-temperature environment when the engine is working, avoiding screw failure due to high temperatures; at the same time, their oil resistance and chemical corrosion resistance can resist the erosion of substances such as engine oil and coolant, ensuring long-term reliable fastening. Compared with metal screws, these screws are lighter, which helps reduce the overall weight of the vehicle and conforms to the development trend of automobile lightweighting.

In the fields of smart homes and outdoor equipment, the weather resistance and convenience advantages of PA66 + 50% glass fiber nylon cross recessed pan head machine screws are particularly prominent. In smart home devices like smart door locks and robot vacuum cleaners, the cross recess design facilitates installation and maintenance, allowing non-professionals to operate easily; their high-strength material can withstand the stress generated by frequent equipment operation, ensuring stable equipment work. In outdoor equipment such as outdoor lamps and solar photovoltaic brackets, the weather resistance of these screws can resist harsh environments like wind, sun exposure, and rain, avoiding fastening failure caused by rust or aging; at the same time, their insulating property can prevent the risk of outdoor electric leakage, ensuring use safety. The pan head structure fits tightly with the outer shell of outdoor equipment, reducing rainwater infiltration and further improving the protective performance of the equipment.

From daily household appliances to the automotive industry, and from smart homes to outdoor facilities, PA66 + 50% glass fiber nylon cross recessed pan head machine screws play a key fastening role in various fields with their high strength, weather resistance, and convenience. With the continuous upgrading of material technology, these screws will further optimize their performance in the future, adapt to more complex scenarios, and become an indispensable fastening solution in industrial production and daily life.
