ibholithi yenqwelo

Ibholithi yenqwelo (ekwabizwa ngokuba yi-coach bolt kunye ne-round-head-square-neck-neck bolt) luhlobo lwebholithi esetyenziselwa ukubopha isinyithi kwintsimbi okanye, ngokuqhelekileyo, umthi kwisinyithi.Ikwabizwa ngokuba yikomityi yentloko yebholiti e-Australia naseNew Zealand.

Ihluke kwezinye iibholithi ngentloko yayo ye-mushroom enzulu kunye nenyaniso yokuba i-cross-section ye-shank, nangona i-setyhula kuninzi lobude bayo (njengakwezinye iintlobo zebholiti), isikwere ngokukhawuleza phantsi kwentloko.Oku kwenza ukuba ibholithi iyazitshixa xa ifakwe ngomngxuma osisikwere kumtya wesinyithi.Oku kuvumela ukuba i-fastener ifakwe kunye nesixhobo esinye kuphela, i-spanner okanye i-wrench, esebenza ukusuka kwelinye icala.Intloko yebholithi yekhareji ikholisa ukuba yidome engekho nzulu.I-shank ayinayo imisonto;kwaye i-diameter yayo ilingana necala le-square cross-section.

Ibholithi yenqwelwana yayilungiselelwe ukusetyenziswa ngepleyiti yokuqinisa intsimbi emacaleni omabini omqadi womthi, inxalenye ephindwe kabini yebholithi ingena kumngxuma osisikwere kumsebenzi wentsimbi.Kuqhelekile ukusebenzisa i-bolt yenqwelo kwimithi engenanto, icandelo lesikwere linika ukubamba okwaneleyo ukukhusela ukujikeleza.

Ibholithi yokuthwala isetyenziswa kakhulu kwizilungiso zokhuseleko, ezifana nezitshixo kunye neehenjisi, apho ibholithi kufuneka ikhutshwe kwicala elinye kuphela.Intloko egudileyo, edowulweyo kunye nesikwere nut ingezantsi inqanda ibholithi yekhareji ukuba ingatshixeki kwicala elingakhuselekanga.
