PA66 Glass Fiber Reinforced Phillips Countersunk Screw
PA66 glass fiber reinforced Phillips countersunk screw is a lightweight engineering plastic fastener designed for applications requiring electrical insulation, corrosion resistance, low weight, and stable dimensional performance. The PA66 glass fiber reinforced Phillips countersunk screw combines nylon 66 material with glass fiber reinforcement, improving strength, stiffness, heat resistance, and long-term durability compared with standard plastic screws.
The PA66 glass fiber reinforced Phillips countersunk screw features a flat countersunk head and Phillips cross recess drive. It provides flush installation in plastic housings, electronic equipment, insulating structures, machinery covers, and OEM assemblies where metal fasteners may cause conductivity, corrosion, or weight concerns.

Product Overview
The PA66 glass fiber reinforced Phillips countersunk screw is engineered for precision fastening in electrical, electronic, and industrial equipment. Its countersunk head allows the screw to sit flush with the mounting surface, creating a smooth appearance and reducing interference in compact assemblies.
Glass fiber reinforced PA66 offers better mechanical strength than unfilled nylon. Therefore, this PA66 glass fiber reinforced Phillips countersunk screw is suitable for applications requiring insulation, chemical resistance, vibration resistance, and stable fastening performance.
As a practical industrial fastener, it is widely used in OEM fasteners, electrical panels, automotive electronics, medical devices, and plastic machinery components.

Materials and Manufacturing Process
The PA66 glass fiber reinforced Phillips countersunk screw is produced through precision plastic molding and secondary finishing processes.
Production starts with high-quality PA66 resin and selected glass fiber reinforcement. The material is dried before molding to reduce moisture and improve dimensional stability. Then, injection molding forms the countersunk head, shank, Phillips recess, and thread profile.
For special requirements, CNC trimming or secondary machining can improve critical dimensions. After molding, parts are cooled under controlled conditions to reduce warpage. Surface cleaning removes residues, while inspection checks thread quality, head angle, drive recess, dimensions, color, and appearance.
Each PA66 glass fiber reinforced Phillips countersunk screw is packed carefully to protect threads and drive geometry during shipment.
