ibholthi yenqwelo

I-bolt yenqwelo (ekwabizwa ngokuba yi-coach bolt kunye ne-round-head square-neck bolt) luhlobo lwe-bolt esetyenziselwa ukubopha isinyithi kwisinyithi okanye, ngokuqhelekileyo, umthi kwisinyithi. Ikwaziwa njenge-cup head bolt e-Australia naseNew Zealand.

Yahlulwe kwezinye iibholiti ngentloko yayo engaphantsi kweekhowa kunye nenyaniso yokuba icandelo elinqamlezileyo le-shank, nangona lijikeleza ubukhulu becala lobude bayo (njengakwezinye iintlobo zebholiti), lisikwere ngaphantsi kwentloko. Oku kwenza ibholiti izivale ngokwayo xa ifakwa kumngxuma osikwere kwintambo yesinyithi. Oku kuvumela ukuba i-fastener ifakwe ngesixhobo esinye kuphela, i-spanner okanye i-wrench, esebenza kwicala elinye. Intloko yebholiti yenqwelo idla ngokuba yidome engaphantsi kweebholiti. I-shank ayinamisonto; kwaye ububanzi bayo bulingana necala lecandelo elingaphezulu kweebholiti.

Ibholthi yenqwelo yenzelwe ukusetyenziswa ngepleyiti yokuqinisa isinyithi kumacala omabini omqadi womthi, inxalenye enesikwere yebholthi ingena kumngxuma osikwere kumsebenzi wentsimbi. Kuqhelekile ukusebenzisa ibholthi yenqwelo ukuze ikhuphe imithi, inxalenye yesikwere inika ukubamba okwaneleyo ukuthintela ukujikeleza.

Ibholithi yenqwelo isetyenziswa kakhulu kwizinto zokhuseleko, ezifana neelokhi kunye neehinge, apho ibholithi kufuneka isuswe kwicala elinye kuphela. Intloko egudileyo, eneedome kunye nenati yesikwere engezantsi ithintela ibholithi yenqwelo ukuba ingavulwa kwicala elingakhuselekanga.
