JIS B 1051 is a Japanese Industrial Standard (JIS) that specifies the mechanical properties of fasteners. Specifically, it covers bolts, screws, and studs made of carbon steel and alloy steel when tested at an ambient temperature range of 10°C to 35°C.

Standards are regularly updated, amended, or reaffirmed to keep pace with modern metallurgy and manufacturing safety rules. Free downloads floating around the web are frequently outdated versions (such as the 2000 or 2014 revisions). Designing a critical, load-bearing mechanical component using obsolete standards can lead to catastrophic structural failures or failed regulatory audits. 3.
