What Is The Strength Of The Threaded Sleeve

The strength of threaded sleeves is one of the key performance indicators, closely related to factors such as materials, manufacturing processes, diameters, and application scenarios.
For example, the tensile strength of a steel threaded sleeve refers to the maximum tensile force it can withstand under tensile load, while the torsional strength refers to the maximum torque it can withstand under torsional load. According to the relevant provisions of the national standard GB/T 1243-2006, the tensile strength of the steel threaded sleeve should not be less than the yield strength of the steel bar, and its torsional strength should not be less than 70% of its tensile strength.
In addition, some specially designed threaded sleeves, such as the T63 straight thread connection sleeve developed by Jiangsu Tongli Metal Products Co., Ltd., use equal diameter angle extrusion to produce cold work hardening of the material to refine the grain, thereby improving its tensile strength, shear strength, and fatigue resistance. Its tensile strength can reach 800-900 megapascals, far exceeding that of ordinary threaded sleeves.
In terms of type, the strength of straight threaded sleeves of different levels may also vary. For example, the first level straight threaded sleeve is mainly used in general mechanical structures, which bear relatively small forces and require low strength; The second level straight threaded sleeve has a wider range of applications and can withstand greater force; The strength grade of the three-level straight threaded sleeve is the highest, mainly used for structures that need to withstand strong forces.
Overall, the strength of threaded sleeves is diverse, and suitable threaded sleeves should be selected based on specific application scenarios and requirements. Meanwhile, during use, it is necessary to strictly follow the relevant installation and usage specifications to ensure the full play of its strength and structural stability.
