A critical aspect of JIS B 1051 is its use of a two-number designation for property classes, such as . The first number represents 1/100th of the nominal tensile strength in MPa, while the second indicates the ratio of yield strength to tensile strength. For example, a class 10.9 bolt has a tensile strength of 1,000 MPa and a 0.9 ratio, giving it a high yield strength.
JIS B1051 is titled This standard ensures that threaded fasteners can withstand specific loads and environmental stresses without failing. It provides the official framework used by Japanese manufacturers (and global companies sourcing parts from Japan) to guarantee structural integrity. Scope of the Standard Materials: Carbon steel and alloy steel. Thread Types: Coarse pitch and fine pitch threads. Size Range: Thread diameters from M1.6 up to M39.
