Igama lemveliso | Stainless Steel Countersunk Head Self Drilling Screws |
Izinto eziphathekayo | Zenziwe ngentsimbi engatyiwa, ezi zikrufu zinokuxhathisa okulungileyo kwikhemikhali kwaye zinokuba nemagnethi encinci |
Uhlobo lweNtloko | Countersunk Head |
Ubude | Ilinganiswa ukusuka phezulu entloko |
Isicelo | Ayenzelwe ukusetyenziswa kunye ne-aluminium sheet sheet. Zonke zigqunywe phantsi kwentloko ukuze zisetyenziswe kwimingxunya eshiyiweyo. Izikrufu zingena kwi-0.025" kunye nentsimbi encinci yephepha. |
Umgangatho | Izikrufu ezidibana ne-ASME B18.6.3 okanye i-DIN 7504-O enemigangatho yemilinganiselo. |
1. Izikrufu zentsimbi estainless zinokumelana kakuhle neekhemikhali kwaye zinokuba nemagnethi encinci.
2. Ubude bulinganiswa phantsi kwentloko.
3. Izikrufu zentsimbi yeshiti/izikrufu zokucofa ziziqhoboshi eziphothiweyo ezinesakhono esikhethekileyo "sokucofa" imisonto yazo yangaphakathi yokukhwela xa iqhutywa kwimingxunya esele ilungisiwe kwimathiriyeli eyitsimbi kunye nezingezizo ezentsimbi.
4. Izikrufu zesinyithi zeshiti / izikrufu zokucofa zinamandla amakhulu, isiqwenga esinye, i-fasteners yecala elinye.
5. Ngenxa yokuba benza okanye basika intambo yabo yokukhwelana, kukho intambo efanelekileyo ngokungaqhelekanga, ephakamisa ukuxhathisa ukukhulula enkonzweni. Izikrufu zentsimbi yeshiti/izikrufu zokucofa zinokuqhawuka kwaye ziphinde zisetyenziswe.
