To certify a fastener under JIS B 1051, manufacturers must subject it to rigorous testing. The primary characteristics defined by this standard include: Conducted on the cross-section or surface using Vickers
The standard specifies critical performance metrics for different "property classes" (e.g., 8.8, 10.9, 12.9): Tensile Strength ( Rmcap R sub m The first number represents in MPa, and the

Fasteners are designated by two numbers (e.g., 8.8, 10.9). The first number represents in MPa, and the second represents the ratio of yield strength to tensile strength. Property Class Nominal Tensile Strength (MPa) Yield Strength (MPa) Typical Material 4.6 / 4.8 Low or medium carbon steel 5.6 / 5.8 Low or medium carbon steel 8.8 Medium carbon steel (Quenched & Tempered) 10.9 Alloy steel (Quenched & Tempered) 12.9 Alloy steel (Quenched & Tempered) 3.
