IiBolt zeHex ezineNgcaciso yeTheyibhile yesi-2:Ezi bholiti ze-hex zibambelela kwiinkcukacha ezichazwe kwiThebhile 2, ngokwesiqhelo ireferensi yemigangatho efana ne-ASTM A307 kunye ne-A354.

Izinto ezikumgangatho ophezulu:Eyenziwe kwizinto ezisemgangathweni ophezulu, ezifana ne-carbon steel okanye i-alloy steel, ezi bhotshi ze-hex ziqinisekisa amandla kunye nokuqina, ukuhlangabezana neemfuno zemigangatho ye-ASTM.

Ii-Aplikeshini eziNyezo:Ifanelekile kwizicelo ezahlukeneyo, kubandakanywa ulwakhiwo, iziseko ezingundoqo, kunye noomatshini, apho ukuqiniselwa okuthembekileyo nokomelela kubalulekile.

Ukuxhathisa ukonakala:Ngokuxhomekeke kwimathiriyeli kunye nokugqiba, ezi hex bolts zinokubonelela ngokuxhathisa umhlwa, zizenze zilungele iimeko zangaphandle kunye nezirhabaxa.

Uluhlu olubanzi lweesayizi:Ifumaneka kuluhlu olubanzi lweesayizi kunye neentambo zentambo ezichazwe yimigangatho ye-ASTM, iqinisekisa ukuhambelana neemfuno ezahlukeneyo zokubopha.

Umgangatho oqinisekisiweyo:Iibholiti ze-Hex ezihambelana nemigangatho ye-ASTM zivavanywa ngokungqongqo ukuqinisekisa ukuba ziyahlangabezana neempawu zoomatshini ezichaziweyo, zibonelela ngesiqinisekiso somgangatho kunye nokusebenza.
