Asme B1864 Pdf
The ASME B18.6.4 standard is a critical technical document established by the American Society of Mechanical Engineers (ASME) that provides comprehensive dimensional and general data for tapping screws and metallic drive screws. Purpose and Scope
- Provide a concise comparison of ASME B186.4 vs. related fitting standards (e.g., ASME B16.9, B16.11).
- List typical material grades referenced (ASTM numbers) and common sizes covered.
- Outline inspection checklist items for incoming cast butt-weld fittings.
As of 2013, the ASME B18.6 subcommittee combined B18.6.4 (Tapping Screws) and B18.6.3 (Machine Screws) into a single document. Why? Over 50% of the content was identical. asme b1864 pdf

The ASME B18.6.4 standard, which covers thread-forming and thread-cutting tapping screws and metallic drive screws (inch series), has been superseded and consolidated into ASME B18.6.3. While the 1998 version (reaffirmed in 2005) is still referenced in legacy projects, users are generally directed to the updated ASME B18.6.3-2024 for the most current data.

Summary — ASME B186.4
ASME B186.4 is the American Society of Mechanical Engineers standard that specifies dimensions, tolerances, markings, and related requirements for butt-weld fittings of cast stainless steels (commonly used in piping systems). It covers types, sizes, material grades, wall thicknesses, and inspection/identification practices to ensure compatibility and safe welding/assembly in pressure piping.
