Key Features and Specifications:
Design: Unlike Self-Tapping Screws, Thread Rolling Screws feature a finer pitch and a thread form resembling that of a machine screw. The trilobular thread shape and slight taper at the end of the screw enable it to form its own threads without requiring a pre-tapped hole.
Material and Coatings: Available in high-quality A2 Stainless Steel, with the option for Chemical Blackening to enhance corrosion resistance and aesthetic appeal.
Sizes: DD Fasteners offers a comprehensive range of diameters and lengths to suit diverse application needs. Standard diameters range from M2 to M12, with lengths from 4mm to 100mm.
Surface Coatings: In addition to the standard stainless steel finish, other surface treatments include zinc plating, black oxide, and various customized coatings to meet specific environmental and durability requirements.
Functional Benefits:
Higher Installation Torque: The larger minor diameter allows Thread Rolling Screws to handle higher installation torque, essential for tougher assemblies.
Thread Strength: By reshaping the material to fit tightly around the screw, the formed threads are generally stronger than those cut by Self-Tapping Screws, ensuring a more secure connection.
Prevention of Cracking: The trilobular shape provides relief areas, reducing the likelihood of thread cracking under pressure.
Application Scenarios:
Industrial Manufacturing: Ideal for use in environments where a firm and reliable connection is crucial, preventing loose components that could lead to operational failures.
Automotive Assembly: Ensures secure fastening in metal and plastic components, withstanding vibration and dynamic loads.
Consumer Electronics: Suitable for assembling plastic enclosures, offering reliable and durable fastening without the risk of material cracking.
Woodworking: Provides strong, self-forming connections in hardwood and engineered wood products without the need for pre-tapping.
