Musiyano pakati pegiredhi 8.8 ne12.9 mabhaudhi

Fekitari yedu inonyanya kugadzira mabhaudhi akasimbayegiredhi 8.8 ne12.9, ine mwero ichinzi DIN933, DIN931, neDIN912, ine zvirevo zvinotangira paM10 kusvika M48.

Saka, chii musiyano pakatigiredhi 8.8 kabhoni simbi mabhaudhi uye giredhi 12.9 mabhaudhi? Ndapota tarisa kuongororo iri pasi apa

1. Simba giredhi uye kuoma. Ose mabhaudhi egiredhi 8.8 ne12.9 ndeemabhaudhi ane simba guru, asi kuomarara kwegiredhi 12.9 mabhaudhi anogona kazhinji kusvika pa39 kusvika 44HRC, ukuwo kuoma kwemabhaudhi egiredhi 8.8 kunowanzova pakati pe22 ne33HRC. Uyu musiyano wekuoma unonyanya kukonzerwa nezvinhu zvakasiyana-siyana zvinoshandiswa. Mabhaudhi eGiredhi 12.9 anowanzo gadzirwa nealloy simbi zvinhu (seSCM435), nepo giredhi 8.8 mabhaudhi achiwanzo gadzirwa nepakati kabhoni simbi zvinhu.

2. Mamiriro ekushandisa. Mabhaudhi eGiredhi 12.9, nekuda kwekuoma kwawo uye kusimba, anowanzo shandiswa mumichina mikuru yemuchina inoda kutsungirira mitoro mikuru, senge mumachira, majekiseni ekuumba, hydraulic, uye maindasitiri emuchina. Grade 8.8 socket screws, nekuda kwekuoma kwadzo uye simba, zvinowanzoshandiswa mumidziyo midiki yemagetsi senge zvigadzirwa zvemagetsi, zvigadzirwa zvedhijitari, uye midziyo yemagetsi.

3. Mutengo. Mutengo wegiredhi 12.9 mabhaudhi kazhinji wakakwira kupfuura giredhi 8.8 mabhaudhi nekuti iwo ane yakakwira tensile simba uye mutoro wemutoro.Mitengo yedu yefekitori yose mitengo yeholesale, iyo inobatsira zvikuru. Tariro yekugamuchira rumwe rutsigiro rwevatengi, ndapota ongorora webhusaiti yeduwww.cnzyl.comkuziva zvakawanda nezvezvigadzirwa zvedu uye kambani yedu.
