Scope: This standard specifies the mechanical properties of bolts, screws and studs made of carbon steel or alloy steel and tested at an ambient temperature of 10 to 35 °C. Products judged to comply with this standard at this ambient temperature may have different mechanical and physical properties at higher or lower temperatures. Appendix A (reminder) provides examples of yield points (σ_s) or specified non-proportional elongation stresses (σ_po.2) at elevated temperatures. Below this ambient temperature, product performance, especially impact toughness may change, users should pay attention. Some fasteners may not meet the tensile or torque requirements of this standard, such as countersunk head, semi-sunk head and cylindrical head (para. Chapter 6). Bolts, screws and studs applicable to this standard: Coarse thread M1.6~M39; fine thread M8×1~M39×3; common thread in accordance with GB/T 192; diameter and stud in accordance with GB/T 193 Combination of pitches; Basic dimensions in accordance with GB/T 196; Tolerances and fits in accordance with GB/T 197; Made of carbon steel or alloy steel. This standard does not apply to set screws and similar non-tension threaded fasteners. This standard does not specify the following performance requirements: Weldability; Corrosion resistance (GB/T 3098.6); Performance requirements for working temperatures higher than +300°C (250°C for class 10.9) or lower than -50°C; Shear resistance stress; fatigue resistance.
