Grade 12.9 mabhaudhi uye screws tarisa kune epamusoro-soro masiruuru akagadzirwa ne35CrMo, 42CrMo, uye B7 alloy simbi zvinhu, zvine hushoma kusimba kwe1220Mpa uye kuomarara kwe39-44HRC. Inonyanya kushandiswa mumachira, hydraulic, jekiseni molding, uye maindasitiri emuchina mudzimba.

1. Iyo 12.9 giredhi sikuruu inoreva ultra-high simba sikuruu yakagadzirwa neSCM435 alloy steel material, ine zvishoma tensile simba re1220Mpa uye kuoma kwe39-44HRC. Inonyanya kushandiswa mumachira, hydraulic, jekiseni molding, uye maindasitiri emuchina mudzimba.

2. Maererano nechinhu chacho, chinogona kugoverwa mumhando dzakasiyana-siyana dzakadai se12.9 giredhi ekunze ane hexagonal mabhaudhi, giredhi 12.9mukati hexagonal head screws(musoro wemukombe), 10.9 giredhi countersunk head internal hexagonal screws (flat cup), 10.9 giredhi semi round head internal hexagonal screws (round cup), 12.9 giredhi set screws (machine meter), 12.9 giredhi mukati hexagonal plug screws, etc. Maererano shinda, yakakamurwa kuita shinda yakaoma, tambo yakanaka, metric, British, American, nezvimwe.

3. Giredhi 12.9 ndiyo mhando yepamusoro yemasiruuru, ine kuomarara kwakanyanya uye kusimba kwesimba. Yayo Rockwell kuoma (HRC) inogona kusvika 39-44, uye simba rayo rekusimba rinogona kusvika 1220N / mm2. Nekudaro, nekuda kweakasiyana maumbirwo ekugadzira sikuruwa, countersunk hex screws (flat cups) uye hafu yeround headed hex screws (yakatenderera mikombe) inogadzirwa kubva kune imwecheteyo inongokwanisa kuwana kushomeka kwekusimba kwegiredhi 10.9. Iyo inogona zvakare kuzadzisa zvizere zvinodikanwa zvemaindasitiri uye emigodhi mabhizinesi ezvimisikidzo muzviitiko zvakakosha uye zvikamu.
