Masikuruu emumaindasitiri anogadzirwa mumhando dzakasiyana-siyana uye zviyero. Masimbi esimbi ane kugona kukuru kwekumisa kushushikana kwakanyanya pasi pekupinzwa kwekupisa, zvichiita kuti sarudzo yesimbi iyi isarudze pakugadzira mabhoti esimbi anoshandiswa muzvivakwa zvemaindasitiri. Masikuru eFerroalloy ane kabhoni yakakwira zvine mwero uye hunhu hwakanyanya kupfuura simbi yakachena, iyo yakapfava zvikuru. Ehe, kuwedzera kukabhoni, makemikari anodzikamisa akadai semanganese, silicon, sarufa, phosphorus, uye dzimwe nguva kunyange vanadium (vanadium inowedzerwa kumakemikari esimbi anoda kusimba) anowanikwa mumakemikari esimbi.
Muindasitiri yekuvaka, mabhaudhi ekuvaka nenzungu anoshandiswa zvakanyanya mukugadzira mashedhi, mabhiriji, madhamu nemagetsi. Kutaura zvazviri, kushandiswa kwemabhaudhi ekuvaka nenzungu kunoitwa nekuchinjisa simbi, zvinoreva mabhaudhi ekuvaka kana kuchinjisa arc uchishandisa maelectrode, zvichienderana nekudiwa kwekubatanidza ndiro yesimbi nedanda. Nzira yega yega yekubatanidza ine zvayakanakira nezvayakaipira, zvatichaongorora pazasi.
Zvikuruu zvekuvaka zvinoshandiswa pakubatanidza matanda ekuvaka zvakagadzirwa nesimbi yepamusoro-soro, kazhinji giredhi 10.9. Giredhi 10.9 zvinoreva kuti simba rekudhonza re structural screw rinosvika 1040 N/mm2, uye rinogona kutsungirira kusvika 90% yekumanikidzwa kwese kunoshandiswa ku screw body munzvimbo inotenderera isina kushanduka zvachose. Zvichienzaniswa ne 4.8 iron, 5.6 iron, 8.8 dry steel, zvikuruu zve structural zvine simba rekudhonza rakawanda uye zvine kurapwa kwakaoma kwekupisa mukugadzirwa.
Kusiyana nemabhaudhi ehexagon nenzungu dzakajairika, mabhaudhi ehexagon nenzungu dzakajairika dzinogadzirwa zvichienderana neDIN931 sehafu yemagiya, zvichienderana neDIN933 semagiya akazara, uye masikurudhi ane hexagonal ari nyore, anowanzogadzirwa zvichienderana neDIN6914. Manuts ekubatanidza pamasikirudhi ane nyama yakawanda uye kureba kupfuura manuts ane hexagon akajairika akagadzirwa kuDIN934, achiratidza kuramba kwakanyanya kwekumanikidzwa, akagadzirwa kuDIN6915. Masikurudhi ekugadzirwa uku akanyorwa 10HV uye anowanzo kuve matt black phosphating kuti adzivirire ngura munzvimbo dzakatikomberedza kana hot dip galvanized kana deep chrome matt silver, ese aine finish yesimbi. Anoshandiswa mu zinc uye ane kuramba kwakanaka munzvimbo dzakatipoteredza.
