Scope

This part of GB/T 3098 specifies the mechanical and physical properties of bolts, screws and studs made of carbon steel or alloy steel and tested at an ambient temperature of 10°C to 35°C. Within this ambient temperature range, fasteners (including bolts, screws and studs, the same below) that meet the technical requirements of this part may not meet the specified requirements at higher (see Appendix B) and/or lower temperatures. Mechanical and physical properties. Some fasteners may not meet the tensile or torque requirements of this standard due to the small head shear area due to the head geometry. These fasteners are, for example, oblate or low cylindrical or countersunk head fasteners with low head height, with or without an outer plate screw part, with an inner plate screw part (see 8.2). Fasteners used in this part: a) Made of carbon steel or alloy steel; b) Ordinary thread in accordance with GB/T 192; c) Coarse thread M1.6~M39; fine thread M8×1~M39 ×3; d) Comply with the combination of diameter and pitch specified in GB/T 193; e) Comply with the tolerance specified in GB/T 197, GB/T 9145 and GB/T 22029. This section does not apply to set screws and similar non-tension threaded fasteners (see GB/T 3098.3). This standard specifies the following performance requirements: — weldability; — corrosion resistance; — resistance to shear stress; — torque-clamping force performance; — fatigue resistance.
