 1 Scope

 This part of GB/T 3098 specifies mechanical and physical properties of bolts, screws and studs made of carbon steel or alloy steel when tested at an ambient environment temperature range of 10℃ to 35℃. Within the range of this environment temperature, as for fasteners (including bolts, screws and studs, the same below) that conform to the technical requirements of this part, at higher (See Appendix B) and/or lower temperature, they are possible to fail to conform to the specified mechanical and physical properties.
Note 1: Fasteners conforming to the requirements of this part are used in applications from -50℃~ to +150℃. Users are advised to consult with the parties concerned for temperatures outside the range of -50℃~ to +150℃ and up to a maximum temperature of +300℃.
Note 2: Information for the selection and application of low temperature and high temperature steels is given, for example, in EN 10269[1], ASTM F2281[3] and ASTM A320/A320M[4].
Certain fasteners might not fulfill the tensile or torsion requirements of this part because the geometry of their heads reduces the shear area in the head. These include fasteners having a low head, with or without external driving feature, a low round or cylindrical head with internal driving feature or a countersunk head with internal driving feature (see Clause 8.2).
This part is applicable to fasteners:
a) Made of carbon steel or alloy steel;
b) Common threads that meet those specified in GB/T 192;
c) With coarse thread 1.6 to M39 and fine pitch thread M81 to M393;
d) With diameter/pitch combinations according to GB/T 193;
e) Having tolerances according to GB/T 197, GB/T 9145 and GB/T 22029;
This part is not applicable to set screws and similar threaded fasteners not under tensile stresses (see GB/T 3098.3).
This part doesn't specify requirements for such properties as:
- Weldability;
- Corrosion resistance; 
- Resistance to shear stress;
- Torsion/clamp force performance; or
- Fatigue resistance.
