This standard covers the general and dimensional data for various types of tapping screws. It is essential for engineers and manufacturers to ensure that screws are compatible with their intended materials and performance requirements.

Scope: Specifies dimensions, tolerances, and general requirements for inch-series tapping screws, including thread-forming, thread-cutting, and drive screws.

Key Metrics: Provides details on head types (e.g., flat, oval, pan, hex), drive styles (e.g., slotted, Phillips), and thread forms.

Material Compatibility: Helps determine the correct screw type for different substrates like sheet metal, plastics, or cast iron to prevent stripping or material failure. How to Access the Official PDF

To ensure you have the most up-to-date and compliant information, you should obtain the document from authorized sources:

ASME Official Store: The primary source for the latest version of ASME B18.6.4.

ASME Digital Collection: A comprehensive ASME Digital Collection for digital access to various codes and standards. asme b1864 pdf

Standards Aggregators: Sites like IHS Markit or ANSI also provide legal PDF downloads for a fee. Implementation Guide for Engineers

Identify Screw Type: Use the standard to differentiate between Type A, AB, and B (thread forming) vs. Type T, F, and BF (thread cutting).

Verify Hole Sizes: The standard includes recommended hole sizes for specific screw diameters to ensure proper thread engagement.

Check Tolerances: Refer to the dimensional tables to ensure manufactured parts meet the specified tolerances for head height and shank diameter.

Reference the ASME Style Guide: If you are citing this standard in a technical paper or report, follow the ASME Style Guide for proper formatting and referencing.

Note: ASME standards are technically voluntary but are often mandated by law or contract in many engineering and construction sectors. Standards & Certification - FAQ - ASME This standard covers the general and dimensional data

ASME B18.64-2010: Standard for Fasteners for Use in Structural Applications

This standard provides specifications for fasteners used in structural applications, including:

Materials: The standard covers fasteners made from carbon steel, alloy steel, stainless steel, and other materials.
Dimensions: It provides dimensional requirements for fasteners, including bolts, nuts, and washers.
Performance: The standard outlines performance requirements for fasteners, including tensile strength, yield strength, and elongation.
Testing: It specifies testing methods and requirements for fasteners, including tensile testing, hardness testing, and impact testing.

Key Features of ASME B18.64-2010:

Unified inch screw threads: The standard specifies the use of unified inch screw threads for fasteners.
Strength grades: It establishes strength grades for fasteners, including Grade 55, 75, 150, and 250.
Marking and labeling: The standard requires fasteners to be marked with their strength grade, material, and manufacturer's identification.

Applications:

ASME B18.64-2010 applies to fasteners used in various structural applications, including:

Building construction
Bridges
Industrial equipment
Machinery

2. Copyright Infringement

ASME aggressively protects its intellectual property. Distributing or downloading unauthorized PDFs can result in fines of up to $150,000 per work under the Digital Millennium Copyright Act (DMCA).

Scenario C: You are auditing an older plant.

The print says: "Per ASME B1864."
Your response: This is a typo. Check the drawing date. If from 1985, cross-reference with the pipe thread standards of that era (ANSI/ASME B1.20.1-1983).

1. Obsolete Data (Safety Hazard)

Even if you stumble upon a real standard (like old B16.5 from 1996), using outdated dimensions can lead to flange leaks, bolt failures, or catastrophic pipe ruptures. ASME updates standards every two years for safety reasons.

3. The B1 Series (Threads)

Often confused with B16/B18, the B1 series covers the geometry of threads.
