screws Torlon 4203 ¼”-20 Screws are used to fasten a composite housing containing radar equipment to an aluminum skinned aircraft. Thirty-six (36) Torlon screws are used to mount the composite housing. Metallic fasteners interfered with the signal. The application required a strong, EMI/RFI transparent material. Customer testing of the screws revealed they carry tensile loads 446 lbs and show strength of 412 lbs. Additionally, Torlon is non-corroding and has high creep resistance. Injection molding was selected for production economics. Threads are specially designed with radiuses in the root to maximize strength and toughness.
