ActiveHigh-strength structural bolting assemblies for preloading—Part 4: System HV—Hexagon bolt with large width across flats and nut assemblies
预载荷高强度栓接结构连接副 第4部分：HV型 大六角头螺栓和螺母连接副
Application Summary AI generated
This standard specifies the dimensions, mechanical properties, and technical requirements for HV-type high-strength structural bolting assemblies, specifically hexagon bolts with large width across flats and matching nuts. It is applied in steel structure engineering, such as bridges, buildings, and heavy machinery, where preloaded bolted connections require high clamping force and reliability under dynamic or static loads. The standard ensures consistent performance in load-bearing joints during construction and testing of steel frameworks.
