Detalye ng paglalarawan

Ayon sa katigasan ng wire wire, nagdadala ng pag-igting, lakas ng ani at iba pa, mayroong isang grade classification ng Hexagon socket bolt, iyon ay, ang antas ng hexagon socket bolt. Ang iba't ibang produkto at materyales ay kinakailangang magkaroon ng iba't ibang grado ng hex socket bolts na naaayon sa kanila. Lahat ng hex socket bolts ay may mga sumusunod na grado:

Ang hexagon socket bolts ay nahahati sa ordinaryo at high strength bolts ayon sa grade strength. Ang ordinaryong hex socket bolts ay tumutukoy sa class 4.8, high strength hex socket bolts ay tumutukoy sa class 8.8 o mas mataas, kabilang ang class 10.9 at class 12.9. Ang hex socket bolts ng grade 12.9 ay karaniwang itim na HEX socket cup head screws na may knurling, natural na kulay at langis.

Ang grado ng pagganap ng hex socket bolts para sa koneksyon ng istraktura ng bakal ay 3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, 12.9, atbp. Mayroong higit sa 10 grado, kung saan ang mga bolts ng grade 8.8 at mas mataas ay ginawa ng low carbon alloy steel o medium carbon steel at heat-treated (quenched, tempered), na karaniwang tinatawag na high strength bolts, at ang iba ay karaniwang tinatawag na ordinary bolts. Ang bolt performance grade label ay binubuo ng dalawang bahagi, na ayon sa pagkakabanggit ay kumakatawan sa nominal tensile strength value at ang buckling ratio ng bolt material.
