Isakhiwo sensimbi yensimbi uhlobo lwensimbi ephezulu yamandla nohlobo lwengxenye ejwayelekile. Izinsimbi zensimbi zensimbi zisetshenziswa kakhulu kubunjiniyela bensimbi ukuxhuma amaphuzu wokuxhuma amapuleti esakhiwo sensimbi. Amabhawodi esakhiwo sensimbi ahlukaniswe ngamakholomu wohlobo lwe-torsional shear kanye namabhawodi amakhulu anezinhlangothi eziyisithupha. Amabhawodi amakhulu anezinhlangothi eziyisithupha anezinga lezikulufo ezijwayelekile, kuyilapho ama-torsional shear type aphezulu-amandla amabhawodi kungukuthuthuka kwamabhawodi amakhulu anamandla amakhulu. Ngokwakhiwa okungcono, ukwakhiwa kwamabhawodi wesakhiwo sensimbi kufanele kuqiniswe kuqala bese ekugcineni. Ekuqiniseni kokuqala kwamabhawodi esakhiwo sensimbi, uhlobo lwethonya lamawrenchi kagesi noma ama-torque amawrenki kagesi ayadingeka. Ukuqiniswa kokugcina kwamabhawodi esakhiwo sensimbi kunezidingo eziqinile. Ukuqiniswa kokugcina kwe-torsional shear type steel structure bolts kumele kusebenzise i-torsional shear type wrench wrench, kanye nokuqiniswa kokugcina kwe-torque yohlobo lwensimbi yamabhawodi kufanele kusetshenziswe uhlobo lwe-torque wrench kagesi. I-torsional shear type steel structure bolt iqukethe i-bolt, i-nut, i-torsional shear type high strength bolt steel steel bolt enkulu ye-hexagonal bolt ne-washer.
