JIS B1051 mandates:
At its core, the standard classifies fasteners into distinct property classes. Property classes ranging from 3.6 to 12.9 are defined, with each class specifying the fastener's minimum tensile strength, yield strength, hardness, and elongation.
It is equally important to know what JIS B 1051 does not cover. The standard does not specify requirements for: Weldability Corrosion resistance Shear stress resistance Torque/clamp force performance Fatigue resistance
The standard was significantly updated in 2014 to align with the international standard ISO 898-1:2013 日本規格協会 JSA GROUP Webdesk Standard Details Full Title jis b1051 pdf free
Fasteners under JIS B1051 are categorized by property classes, which are designated by two numbers separated by a dot (e.g., 4.6, 8.8, 10.9, 12.9). Understanding this numbering system is crucial for selecting the right component. Decoding the Numbering System
There are various legitimate standards aggregators (like Techstreet, IHS Markit, or SAI Global) that sell JIS standards legally.

If you work for an enterprise engineering firm, check if your organization subscribes to standard databases like IHS Markit, Techstreet, or ASTM Compass, which often include JIS libraries.
Ensures the metal is uniform in hardness across its cross-section.
Leading global bolt manufacturers often compile the torque, tension, and grade tables of JIS B1051 into free, downloadable technical handbooks. Conclusion The standard does not specify requirements for: Weldability

Explains how the property class numbers are derived (e.g., the first number relates to nominal tensile strength).
If you are searching for a , you are likely looking for the technical specifications of bolts, screws, and studs made from carbon or alloy steel. This Japanese Industrial Standard is essential for engineers and manufacturers to ensure that fasteners can handle the mechanical stress of their specific applications.
is the definitive Japanese Industrial Standard that outlines the mechanical and physical properties of fasteners made of carbon steel and alloy steel . Specifically covering bolts, screws, and studs featuring coarse and fine pitch threads, this standard ensures global compatibility as it is identical (IDT) to the international standard ISO 898-1 .
