Iinkcukacha ezininzi ze-ASTM zifuna intloko ye-hex enkulu kunomgangatho (ogqityiweyo) wentloko ye-hex.Ezi nkcukacha ziquka: A193, A320 kunye A307B.Nangona iibholiti ze-A325 kunye ne-A490 zikwafuna intloko enzima ye-hex, nceda ubhekisele kwiiBolts zoLwakhiwo malunga nemilinganiselo yobukhulu, kuba ezi bholiti zinemisonto emfutshane yobude kuneebholiti zeheksi eziqhelekileyo.
Isicelo seeBolt zeHex enzima
Iibholiti ezinzima zehex zinokusetyenziselwa izicelo ezininzi ezahlukeneyo ezibandakanya ukuqhoboshela iinkuni, intsimbi, kunye nezinye izinto zokwakha kwiiprojekthi ezinje ngeedokhi, iibhulorho, ulwakhiwo lohola wendlela, kunye nezakhiwo.Iibholiti ezinzima zeheksi ezineentloko ezibunjiweyo nazo ziqhele ukusetyenziswa njengeebholiti zeankile ezinentloko.
Iibholiti ze-heavy hex zesakhiwo ngundoqo kuluhlu lweebholiti ze-handan, ingakumbi i-astm a325, a490,DIN6914 ezifuneka kakhulu kwaye zisetyenziswa kwiiprojekthi zokwakha ezifana netonela kunye nebhulorho, umzila kaloliwe, i-oyile negesi, kunye neshishini lamandla omoya.
Ibholithi yoLwakhiwo lweNsimbi
Ibholithi yesakhiwo sentsimbi luhlobo lwebholithi yamandla aphezulu, kwaye luhlobo lwamalungu asemgangathweni.Ukusebenza ngokukhawuleza kubhetele, kusetyenziselwa isakhiwo sensimbi, ubunjineli, ukwenzela ukuba umphumo wokukhawuleza.Kwisakhiwo sensimbi ngokubanzi, iibholiti zesakhiwo sensimbi kufuneka zibe ngaphezu kwebanga le-8.8, kunye nebanga le-10.9 kunye nebanga le-12.9, zonke ezo ziyi-bolts zensimbi eziphezulu.
Ibholithi yolwakhiwo lwentsimbi yahlulwe yaba yibholithi yokuqina okuphezulu kwe-torsional kunye nebholiti enkulu enehexagonal yokuqina okuphezulu, ibhonti enkulu enehexagonal yokuqina okuphezulu yenqanaba eliphezulu lesikrufu esiqhelekileyo, kunye nohlobo lokucheba lwebholithi yokuqina okuphezulu kuphuculo olukhulu. ibholithi enehexagonal high-strength, ukwenzela ulwakhiwo olungcono.
Ukwakhiwa kweebholithi zesakhiwo sentsimbi kufuneka kuqala kuqiniswe kwaye emva koko kuqiniswe, kwaye iibholithi zesakhiwo sentsimbi kufuneka zisebenzise uhlobo lwempembelelo yombane okanye i-torque adjustable wrench yombane;Kwaye ukuqina kokugqibela kweebholithi zesakhiwo sentsimbi zineemfuno ezingqongqo, ukuqina kokugqibela kweebholithi zentsimbi ye-torsion shear kufuneka kusetyenziswe isikrufu sombane sohlobo lwe-torsional shear, i-torque yokugqibela yokuqinisa iibholithi zesakhiwo sentsimbi kufuneka zisebenzise uhlobo lwe-torsional wrench yombane.
Ibhawunti enkulu yesakhiwo esinehexagon ibandakanya ibhawuthi enye, indongomane enye, kunye neempahla ezimbini zokuvasa.
Iibholiti ezinkulu zehexagon zesakhiwo sentsimbi.
Ibholithi yolwakhiwo lwentsimbi yokucheba ibandakanya ibholithi, indongomane kunye newasha.
