Umahluko phakathi kweebhalts kunye nezikere:
1. I-Bolts ngokubanzi kufuneka isetyenziswe ngokudibeneyo kunye namantongomane. I-Screws zinokukrolwa ngokuthe ngqo kwi-matrix yeentambo zangaphakathi;
2. Iibholiti kufuneka zityibilikisiwe kwaye zitshixiwe ngomgama oqinileyo, kwaye amandla okutshixa ezikrweqe amancinci.

Unokujonga kwakhona kwi-groove kunye nentambo entloko.
Emantloko kukho ii-grooves ezinokugqitywa njengama-screws amakhulu kunye nocingo lomsila we-drill, njenga: i-groove yelizwi, i-groove yomnqamlezo, i-hexagon yangaphakathi, njl, ngaphandle kwe-hexagon yangaphandle;
Izikhuselo ezinentambo yangaphandle yentloko efuna ukufakelwa i-welding, riveting kunye nezinye iindlela zokufaka zezesikrelem;
Isikroba sesentambo esisesokucofa amazinyo, amazinyo ngamaplanga, amazinyo anxantathu okutshixeka angawokrozo;
Eminye imisonto yangaphandle yeyebhedi.

Umahluko wokusebenza phakathi kwezikrufu kunye neebholithi

IBolt:
1. Isigcina-ntloko esineenxalenye ezimbini, intloko nesikere (isilinda esinentambo yangaphandle), esiya kuhambelana kunye ne-nati ukuze siqiniswe kwaye sidibanise iinxalenye ezimbini ngemingxunya. Olu hlobo lonxibelelwano lubizwa ngokuba yi-bolt connection. Ukuba i-nati ayikhutshiwe kwi-bolt, la macandelo mabini angahlulahlulwe, ke unxibelelwano lwe-bolt lolunxibelelwano olunokuchitheka.
2. Isikulufu somatshini sisetyenziselwa ikakhulu ukunxibelelana okukhawulezayo phakathi kwenxalenye yomngxunya kwilayini yangaphakathi kunye nenxalenye enomngxunya ngaphakathi. Umsonto omkhulu wokuqhubekisa awudingi umlinganiso we-nut (olu hlobo lonxibelelwano lubizwa ngokuba yi-screw uxhumano kwaye luyakudibanisa nochaphazeleko; Iyakwazi ukudityaniswa kunye ne-nati yokuqinisa ngokukhawuleza phakathi kwamacala amabini ngemingxunya. Isikreyi sokuseta sisetyenziswa ikakhulu ukulungisa indawo yokuhlangana phakathi kwamalungu amabini.
3. I-screws zokuzitsalela ngokwakho: ziyafana nomatshini wokukrola, kodwa umsonto kwisikali eso sisikali esikhethekileyo sokuzikhuphela ngokwakho. Isetyenziselwa ukomelela kunye nokudibanisa amalungu amabini esinyithi ukuze ubenzele lilonke. Iibhloko mazenziwe kumalungu ngaphambili. Ngenxa yobunzima obuphezulu beekhreyithi, banokukrolwa ngokuthe ngqo kwimingxunya yamalungu ukuba benze imicu yangaphakathi ehambelana nemingxunya yamalungu.
4. Izikhuni zokhuni: ziyafana nomatshini wokukroba, kodwa intambo kwisikhafu yile yesikere somthi esikhethekileyo, esinokukrolwa ngokuthe ngqo kwilungu leenkuni (okanye inxenye) yokuqinisa inxalenye yesinyithi (okanye yintsimbi) ngomngxunya kwilungu leenkuni. Olu hlobo lonxibelelwano luyasuswa.
