THE SOLUTION

AISI 300 Series based bi-metal self-drilling uye self-tapping screws:

Mhinduro yekugadzira yakanyanya kunaka yekuzviboora uye self-tapping screw, ndeye:

• Kubatanidza chikamu chikuru che screw yakagadzirwa neAISI 300 series Stainless Steel. 
• Kuve nedhiri-poindi uye yekutanga kubaya shinda mune yakaomeswa Carbon Steel.
•  
• • Iyo yakaomeswa Carbon Steel chikamu (chibhorani poindi uye yekutanga tambo) ichaita kuchera uye kugogodza iyo inoteverwa nesimbi isina tsvina chikamu ichienda mukushandisa uye inoumba chigarire kugadzirisa.
  • Mhinduro iyi inounza pamwechete zvese zvakanakisa kubva kunyika mbiri, uko main screw act uye inoshanda chaizvo sezvakangoita China yepakutanga yakagadzira self-tapping screws - chete nekuwedzera ficha apo vanoisa vanochengetedza nguva yakawanda nekuzviboora nekuzvibaya-baya. akadaro screws achiita maitiro ese mune imwe kuenda.
  • Iye zvino zvinogoneka kuita zvigadziriso zvekuvaka uchishandisa yakakodzera simbi isina tsvina yekushandiswa kwese kwekunze munzvimbo dzakaoma; nzvimbo yemahombekombe uye maindasitiri, nezvimwe.
    
  • 
  • Kuzviboora uye kuzvirovera screws kunodikanwa munyika yedu yemazuva ano umo "nguva imari" uye uko kukurumidza kuisirwa kumhanya kunotarisirwa mune zvese zviitiko. Ikozvino zvinongogoneka kuona kuisirwa nekukurumidza pasina kubaira chero chinhu - musanganiswa wakakodzera wekukurumidza kuisirwa kumhanya kuwana yekuzviboora uye yekuzvirova-rova-tapa screw ine yakanakisa corrosion kuita mune isina-brittle uye ductile hunhu.
