Vijaki z visoko trdnostjo, znani kot pari spojnih sklopk z visoko trdnostjo, so veliko močnejši od običajnih vijakov in se pogosto uporabljajo v velikih, trajnih napeljavah. Ker je povezovalni par visokotrdnih vijakov poseben in ima visoke tehnične zahteve, se je treba ukvarjati with rain and moisture during transportation, especially to prevent damage to the thread of high-strength bolts, and to be lightly loaded and unloaded during handling.When high-strength bolts enter the site, they need to conduct entrance inspection, mainly for the torque coefficient inspection. The torque coefficient inspection of high-strength bolts is carried out on the torque coefficient tester, and the mean value and standard deviation of the torque coefficient are measured during the test.
