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 zeSakhiwo malunga nemilinganiselo yobukhulu, kuba ezi bholiti zinemisonto emfutshane yobude kuneebholiti ze-hex ezinzima.
Isicelo seeBolt zeHeavy Heavy
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 zehex ezineentloko ezibunjiweyo nazo ziqhele ukusetyenziswa njengeebholiti zeankile ezinentloko.
Iibholiti ze-heavy hex zesakhiwo ngundoqo woluhlu lweebholiti ze-handan, ingakumbi i-astm a325, a490,DIN6914 ezifuneka kakhulu kwaye zisetyenziswa kwiiprojekthi zolwakhiwo 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 zifuneka ukuba zibe ngaphezu kwebanga lesi-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 nebhowunti enkulu enehexagonal yokuqina okuphezulu, ibholithi enkulu enehexagonal ephezulu yenqanaba eliphezulu lokomelela kwesikrufu esiqhelekileyo, kunye nohlobo lokucheba lwebholithi yokuqina okuphezulu kuphuculo olukhulu. ibholithi enehexagonal high-strength, ukwenzela ulwakhiwo olungcono.
Ukwakhiwa kweebholiti 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 okokugqibela ukuqiniswa 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 neewasha ezimbini.
Iibholiti ezinkulu zehexagon zesakhiwo sentsimbi.
Ibholithi yolwakhiwo lwentsimbi yokucheba ibandakanya ibholithi, indongomane kunye newasha.
