Ingcaciso yeMveliso

Ubunjineli obuchanekileyo:I-Undercut 82-degree Flat Countersunk Head Screws ibambelela kwiinkcukacha ezichanekileyo ezichazwe kwi-ASME B 18.6.3 - 2013, iqinisekisa imilinganiselo echanekileyo kunye nokusebenza okufanayo. Ihambelana nemigangatho ye-ASTM F837 kunye ne-F468, ezi zikrufu ziqinisekisa ukuthembeka kwizicelo ezifunayo.

Uyilo olusezantsi:I-undercut feature yezi zikrufu ibonelela ngokugungxulwayo xa ifakelwe, inciphisa i-protrusion yenkangeleko ebhityileyo nephucukileyo. Olu luyilo lukwaphucula ukukwazi kwesikrufu ukusasaza amandla omthwalo ngokulinganayo, okunegalelo ekuphuculeni uzinzo kunye nokuthembeka.

Intloko ye-Flat Countersunk:Yenziwe ngentloko ye-countersunk ecaba, ezi zikhonkwane zenza indawo egungxulwayo xa zifakwe, zinciphisa umngcipheko wokurhweba kunye nokubonelela ngokugqitywa okucocekileyo. Idizayini yentloko ethe tyaba inika indawo eyaneleyo yendawo yokuthwala imithwalo, iphucula amandla apheleleyo edibeneyo edibeneyo.

Usetyenziso Oluguquguqukayo:I-Undercut 82-degree Flat Countersunk Head Screws ifanelekile kuluhlu olubanzi lwezicelo, kubandakanywa iimoto, i-aerospace, kunye noomatshini. Ubungakanani bazo obuchanekileyo kunye nolwakhiwo olomeleleyo lubenza balungele imisebenzi ebalulekileyo yokuqinisa apho ukuthembeka kubaluleke kakhulu.
