Imiyoboro irekuye ifata igishushanyo cyo kongeramo akantu gato ka diameter. Hamwe niyi ntoya ya diameter, imigozi irashobora kwomekwa kumuhuza, kugirango itagwa byoroshye. Bitandukanye n’imigozi isanzwe, umugozi urekuye ntushingiye kumiterere ya screw ubwayo kugirango wirinde kugwa, ariko umenya umurimo wo kwirinda kugwa mumiterere yubukwe hamwe nigice cyahujwe.
Iyo imigozi yashizwemo, umugozi muto wa diameter ufatirwa hamwe hamwe nu mwobo uzamuka wigice cyahujwe kugirango uhuze neza. Igishushanyo cyongera cyane imbaraga nubwizerwe bwihuza, cyaba gikorerwa kunyeganyega hanze cyangwa imitwaro iremereye.
