Industrial screws inogadzirwa mumhando dzakasiyana-siyana uye zviyero.Steel alloys ane yakakwirira kwazvo kukwanisa kumisa kushushikana kwakanyanya pasi pesimba rekupisa kupisa, zvichiita kuti kusarudzwa kweiyi alloy pakugadzira mabhaudhi esimbi anoshandiswa mukugadzirwa kwemaindasitiri.Ferroalloy simbi dzine mwero wakakwira kabhoni wekuwedzera uye zvinhu zvakakwirira zvakanyanya kupfuura simbi yakachena, iyo yakanyanya kupfava.Of,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,. sarufa, phosphorus, uye dzimwe nguva kunyange vanadium (vanadium inowedzerwa kune simbi yesimbi inoda elasticity) inowanikwa mumagetsi esimbi.
Muindasitiri yekuvaka, mabhaudhi ezvivakwa uye nzungu anoshandiswa zvakanyanya mukugadzirwa kwemashedhi, mabhiriji, madhamu uye zvidyarwa zvemagetsi.Kutaura zvazviri, kushandiswa kwemabhaudhi ezvimiro uye nzungu kunoitwa alternately nemasimbi ekuisa, izvo zvinoreva kuti mabhaudhi emugadziriso kana arc welding uchishandisa maelectrode, zvichienderana nekudikanwa kwendiro uye kuve neayo nzira yekubatanidza simbi. zvakaipa, izvo zvatichaongorora pazasi.
Masikirwo emagetsi anoshandiswa pakuvaka matanda ekubatanidza anogadzirwa nesimbi yepamusoro-giredhi, anowanzo giredhi 10.9 simbi.Grade 10.9 zvinoreva kuti tensile simba density of structural screw inenge 1040 N/mm2, uye inogona kumira kusvika 90% yekushungurudzika kwese kunoshandiswa kune screw body munharaunda isina 5.8 elastic iron, simbi yakaoma 48.8 iron. simbi, zvimiro zvemasikiru zvine yakakwira tensile simba uye zvine zvakanyanya kuoma kupisa kurapwa mukugadzira.
Yakasiyana neyakajairwa hexagon mabhaudhi nenzungu, iyo yakajairwa hexagon bolts nenzungu inogadzirwa zvinoenderana neDIN931 chiyero sehafu yegiya, zvinoenderana neDIN933 chiyero segiya rakazara, uye maseruru ane hexagonal ari nyore, anowanzo kugadzirwa maererano neDIN6914 standard.Coupling nzungu pane structural screws uye 3 screws yakakwirira inogadzirwa kune DIN933 yakakwirira yenyama inogadzirwa zvakare kune DIN933 yakakwira hex. stress resistance, inogadzirwa kuDIN6915.Masvikiro echivakwa ichi akanyorwa 10HV uye anowanzo matt black phosphating yekuvandudzwa kwezvakatipoteredza rust resistance kana inopisa dip galvanized kana yakadzika chrome matt sirivheri, zvose zvine metallic finish.Iyo inoshandiswa mu zinc uye ine yakanaka yekudzivirira kwezvakatipoteredza.
