Kukho umahluko emibini phakathi kweebholiti kunye nezikrufu:
1. Iibholiti ngokubanzi kufuneka zisetyenziswe ngokubambisana namantongomane. Izikrweqe zinokudityaniswa ngokuthe ngqo kwi-matrix yeentambo zangaphakathi;
2. Iibholiti kufuneka zikrwelwe kwaye zitshixiwe ngomgama oqinileyo, kwaye amandla okutshixa ama-screws amancinci.

Unokujonga kwakhona kwi-groove kunye nentambo entloko.
Entloko kukho i-grooves inokumiselwa njenge-screws enkulu kunye ne-drill wire wire, njenge: igama elithi groove, i-cross groove, i-hexagon yangaphakathi, njl., ngaphandle kwe-hexagon yangaphandle;
Izikrweqe ezinentloko yomsonto wangaphandle ekufuneka zifakelwe nge-welding, riveting kunye nezinye iindlela zokufakela zezezikrufu;
I-Screw thread yeyamazinyo okucofa, amazinyo eplanga, amazinyo okutshixa anonxantathu ngawezikrufu;
Eminye imisonto yangaphandle yeyeebholiti.

Umahluko wokusebenza phakathi kwezikrufu kunye neebholiti

Ibholithi:
1. I-fastener equlethwe ngamacandelo amabini, intloko kunye ne-screw (i-cylinder enentambo yangaphandle), eya kuhambelana ne-nut yokuqinisa kunye nokudibanisa iinxalenye ezimbini ngemingxuma. Olu hlobo loqhagamshelwano lubizwa ngokuba yi-bolt connection. Ukuba i-nati ayikhutshwanga kwibholiti, la malungu mabini anokwahlulwa, ngoko ke udibaniso lwebholithi lololuqhagamshelo oluqhawukayo.
2. Isikrufu somatshini sisetyenziselwa ikakhulu ukudibanisa ukuqinisa phakathi kwenxalenye enomngxuma kwintambo yangaphakathi kunye nenxalenye enomngxuma kwi. Umsonto omkhulu we-drill awufuni ukuthelekiseka kwe-nut (olu hlobo loqhagamshelwano lubizwa ngokuba luqhagamshelwano lwe-screw kwaye lukwaludibaniso oluqhawukayo; Ingafakwa kwakhona nge nut yokuqhoboshela phakathi kwamalungu amabini anemingxuma ephumayo. Isikrufu sokucwangcisa sisetyenziswa ikakhulu ukulungisa indawo ezalanayo phakathi kwamalungu amabini.
3. I-self-tapping screws: efana ne-screws yomatshini, kodwa intambo kwi-screw yi-screws ekhethekileyo yokuzibamba. Isetyenziselwa ukuqinisa kunye nokudibanisa amalungu amabini esinyithi abhityileyo ukuze enze yonke into. Imingxuma kufuneka yenziwe kumalungu kwangaphambili. Ngenxa yobunzima obuphezulu be-screws, zinokuthi zifakwe ngokuthe ngqo kwimingxuma yamalungu ukuze zenze imicu yangaphakathi ehambelanayo kwimingxuma yamalungu.
4. Izikrufu zomthi: nazo ziyafana nezikrufu zomatshini, kodwa umsonto okwisikrufu seso sikrufu somthi esikhethekileyo, esinokujijwa ngokuthe ngqo kwilungu lomthi (okanye inxalenye) yokuqhoboshela intsimbi (okanye engeyiyo intsimbi) inxalenye nge. umngxuma ophumela kwilungu leplanga. Olu hlobo loqhagamshelwano nalo luyasuswa.
