Prevents the screw from shearing under high torque.
The number "1864" does not fit into any active ASME catalog. The most plausible explanations for the search term "ASME B1864 PDF" include:
To accommodate assembly line automation, the document details the depth, width, and penetration tolerances for: Type I (Phillips) Type IA (Pozidriv) Type II (Frearson) Type III (Slotted) Type IV (Square socket) 3. Thread Profiles and Pitch
Academic institutions and corporate engineering departments often maintain enterprise subscriptions through aggregate standard networks like IHS Markit, Techstreet, or ANSI’s webstore. asme b1864 pdf
Some large engineering firms create internal standards like "TR-B1864" (Technical Requirement B1864). A user searching for this might incorrectly prefix it with "ASME."
If you are working in a European or ISO-focused environment, note that (Thread inserts for ISO metric screw threads) is similar but not identical to ASME B18.64. Always confirm which standard your design or customer requires.
Precise head diameter, head height, body diameter, and length requirements. Prevents the screw from shearing under high torque
Designed to form a mating thread without removing material.
You can purchase and download the digital PDF directly from the American Society of Mechanical Engineers website.
When working with fastening solutions in industrial, manufacturing, or construction environments, selecting the correct screw standard is critical to structural integrity. is a primary standard covering thread-forming and thread-cutting tapping screws, as well as metallic drive screws. Always confirm which standard your design or customer
To obtain a legitimate, fully compliant copy of the ASME B18.6.4 PDF:
The standard defines types such as (spaced thread for sheet metal), Type B (blunt tip for plastics/metals), and Type C (machine screw thread). 4. Dimensional and Performance Requirements
Fasteners governed by this standard are deployed across several distinct industries:
Spaced threads with a sharp, gimlet point. Primarily utilized in thin sheet metal or resin-filled plywood.
