The standard, titled "Thread Forming and Thread Cutting Tapping Screws and Metallic Drive Screws (Inch Series)," serves as the definitive engineering blueprint for self-tapping fasteners used across global manufacturing, automotive, and structural assembly lines. Sourced directly through the ANSI Webstore or the official ASME Standard Catalog , this technical document details critical tolerances, dimensions, geometry, and performance metrics required to ensure mechanical reliability. For engineers, procurement specialists, and quality control professionals, having an authorized ASME B18.6.4 PDF is essential to eliminate production errors and ensure proper joint integrity. What is the ASME B18.6.4 Standard?
Often confused with B16/B18, the B1 series covers the geometry of threads.
Provides complete general and dimensional data for thread-forming and thread-cutting tapping screws and metallic drive screws recognized as "American National Standard". Screw Types Covered:
Thread-cutting screws feature cutting edges or cavities at the point. They physically remove material to carve a clean mating thread, reducing installation torque.
Features machine screw threads with a blunt point and multiple cutting grooves. Extensively used in heavy-gauge sheet metal, structural steel structural sections, zinc castings, and cast iron.
Official copies are available through authorized distributors: : Purchase the latest consolidated standard. ANSI Webstore : Access the 1998 (R2005) historical version.
