Wait, is there a possibility that some versions or copies are leaked online? I should avoid promoting that and instead guide the user to official sources. Also, maybe mention that the JIS website allows ordering the standard, and in some cases, the standard might be referenced in other documents. For example, international standards like ISO sometimes reference JIS, so cross-referencing could be a method. jis b1051 pdf free

Fasteners governed by JIS B 1051 utilize a distinct two-number designation system (such as 4.6, 8.8, 10.9, or 12.9) to state their nominal tensile strength and yield point. Represents Requirements for Vickers (HV), Brinell (HBW), and Rockwell
The maximum stress a fastener can withstand before it breaks in tension.
JIS B 1051 is an essential standard for fastener quality that covers everything from material properties to test methods for bolts, screws, and studs. Multiple free resources are available—most notably the Japanese text at kikakurui.com, the JSA preview page, and technical excerpts from Japanese manufacturers. For complete, reliable data, purchase the official standard, which serves as the definitive source for all engineering, quality control, and regulatory requirements.
