Kunokwehluka okubili phakathi kwama-bolts kanye nezikulufo:
1. Ama-bolts ngokuvamile kudingeka asetshenziswe ngokuhlangana namantongomane. Izikulufo kungenziwa screw ngqo kwi matrix of imicu yangaphakathi;
2. Ama-bolts adinga ukuklwebulwa nokukhihlwa ngebanga eliqinile, futhi namandla okuvala izikali mancane.

Ungabheka futhi i-groove nentambo ekhanda.
Ekhanda kukhona ama-grooves anganqunywa njengezikulufo ezinkulu kanye nocingo lomsila wokudonsa, okufana: i-groove yamagama, i-cross groove, i-hexagon yangaphakathi, njll., Ngaphandle kwe-hexagon engaphandle;
Izikulufa ngentambo yangaphandle ekhanda edinga ukufakwa nge-welding, riveting nezinye izindlela zokufaka ingezama-screws;
Intambo yesikulufa ingeyokushaya kwamazinyo, amazinyo wokhuni, amazinyo angunxantathu okhiye angawokugcotshwa;
Eminye imicu yangaphandle ingeyamasimbi.

Umehluko wokusebenza phakathi kwezikulufo namabhulothi

I-Bolt:
1. Isifakelo esinezingxenye ezimbili, ikhanda nesikulufa (isilinda ngentambo yangaphandle), esizofaniswa ne-nati yokuqinisa nokuxhuma izingxenye ezimbili ngezimbobo. Lolu hlobo lokuxhuma lubizwa ngokuthi ukuxhuma kwe-bolt. Uma i-nati ingasuswanga kusuka kubhulothi, lezo zingxenye ezimbili zingahlukaniswa, ngakho-ke ukuxhumeka kwe-bolt kungokwokuxhuma okungatholakali.
2. Isikulufa somshini sisetshenziselwa ukuxhumana okusheshayo phakathi kwengxenye enomgodi ngentambo yangaphakathi nengxenye enembobo ngaphakathi. Umucu omkhulu wokudonsa awudingi ukufana kwe-nati (lolu hlobo lokuxhumana lubizwa ngokuthi i-screw uxhumano futhi luxhumeka futhi; futhi lungafakwa ne-nati yokuqinisa ngokushesha phakathi kwezingxenye ezimbili ngezigxobo. Isikulufa sokusetha sisetshenziselwa ikakhulukazi ukulungisa isikhundla esihlobene phakathi kwezingxenye ezimbili.
3. Izikulufu zokuzithwebula: ziyafana nezikulufo zomshini, kepha intambo esesibeni yilezo ezikhethekile zokuzibopha. Isetshenziselwa ukuqinisa nokuxhuma amalunga amabili ensimbi ukulenza lilonke. Izinduku kufanele zenziwe kumalungu ngaphambi kwesikhathi. Ngenxa yobulukhuni obuphezulu bezikhonkwane, zingaklwebeka ngqo emigodini yamalungu ukuze zenze imicu yangaphakathi ehambisanayo kwizimbobo zamalungu.
4. Izikulufu zokhuni: ziyafana nezikulufo zomshini, kepha intambo esesibeni yileso esikhethekile sokhuni, esingafakwa sibhekise ngqo kwilungu lezinkuni (noma ingxenye) yokuqinisa ingxenye yensimbi (noma engeyona insimbi) umgodi kwilungu lezinkuni. Lolu hlobo lokuxhuma nalo luyasuswa.
