For companies maintaining ISO 9001 or IATF 16949 (Automotive Quality Management) certifications, auditors require proof of licensed, up-to-date standards. Using a bootleg or unverified PDF can result in immediate audit non-compliance. How to Properly Access JIS B1051
The standard was revised in 2000 to align more closely with , removing older, specific Japanese properties (like 4T-7T classes). A further revision in 2014 updated the standard to match the 2013 version of ISO 898-1. Mechanical Properties Covered in JIS B1051
It is essential for quality assurance in manufacturing, construction, and automotive industries, especially in Japan and countries referencing JIS.
: Minimum and maximum values for tensile strength, yield stress, elongation, and hardness. Test Methods
To comply with JIS B1051, manufacturers must subject fasteners to rigorous mechanical testing. These tests ensure the components will not shear or deform prematurely under load: jis b1051 pdf free
Covers fasteners with coarse and fine pitch threads. Material: Carbon steel and alloy steel.
The indicates 10 times the ratio between the lower yield point ( ReLcap R sub e cap L end-sub proof strength ( Rp0.2cap R sub p 0.2 end-sub ) and the nominal tensile strength. Fastener Property Class Reference Table
: Occasionally, the JSA may offer free or reduced-cost access to standards, but this is rare and usually for very specific standards or promotional materials.
Coarse pitch thread M1.6 to M39, and fine pitch thread M18 × 1 to M39 × 3. For companies maintaining ISO 9001 or IATF 16949
It is the direct Japanese counterpart to the international standard and the American ASTM F568M . Understanding this document is critical for ensuring fastener safety, torque consistency, and failure prevention in everything from automotive assembly to bridge construction.
JIS B1051 is a Japanese Industrial Standard (JIS) that specifies the . Specifically, it covers bolts, screws, and studs when tested at an ambient temperature range of 10°C to 35°C. The standard establishes clear guidelines for: Tensile strength limits Yield strength or proof load characteristics Hardness requirements (Rockwell, Brinell, Vickers) Impact strength for specific property classes Test methods to verify these mechanical properties Key Property Classes (Strength Grades)
Many global fastener manufacturers publish comprehensive technical appendices in their catalogs that reprint the exact torque, yield, and tensile tables from JIS B1051 for customer reference completely free of charge.
One of the most common questions regarding JIS B1051 is how it relates to international standards. A further revision in 2014 updated the standard
What is the (temperature and stress levels) of the assembly?
One reason engineers search for the JIS B1051 document is to find international cross-references. Because Japan heavily aligned its industrial standards with global bodies in recent decades, .
JIS B1051 is a standard published by the Japanese Standards Association (JSA). It specifies the mechanical properties of bolts, screws, and studs made of carbon steel and alloy steel when tested at an ambient temperature range of 10°C to 35°C.
When working with Japanese industrial machinery, automotive components, or global engineering projects, sourcing the correct technical standards is critical. One of the most frequently searched specifications in this domain is , which governs the mechanical properties of carbon steel and alloy steel fasteners.
