Ni irihe tandukaniro riri hagati yimitwe ya compteunk na imitwe ya screw

Countersunk na non countersunk nubwoko bubiri bwibanze bwibishushanyo mbonera. Imitwe idahwitse irimo imitwe ihambiriye, imitwe ya buto, imitwe ya silindrike, imitwe izengurutse, imitwe ya flange, imitwe ya mpande esheshatu, imitwe y'isafuriya, umuzenguruko, kare, imitwe ya truss, nibindi, mugihe ibishushanyo mbonera byumutwe birimo imitwe iringaniye, ellips, numutwe wamahembe.
Umutwe wa Countersunk screw wagenewe guhindurwa cyangwa munsi gato yubuso bwibikoresho nyuma yo kwishyiriraho byuzuye. Ifite imiterere ihuriweho hamwe na shobora hejuru. Intego yumwobo wa konti ni ugukora ubuso bunoze kandi bumwe nyuma yo gukomera umugozi. Mugihe imashini ya comptersunk yamaze gushyirwaho byuzuye, umutwe uzasukurwa cyangwa munsi gato yubuso bwibintu, bigere kumurongo ugaragara. Imiyoboro ya Countersunk isanzwe ikoreshwa mugihe hagomba gukenerwa ubuso bunoze kandi bworoshye, kandi burakoreshwa muburyo bwo gukora ibiti, akabati, hamwe na progaramu ishyira imbere ubwiza n'imirongo isukuye.
Kurundi ruhande, imitwe ya screw idasubirwaho ntabwo ifite imiterere ihuriweho cyangwa hejuru yegeranye, umutwe ugaragara rwose. Intego yabo yo gushushanya ntabwo ari uguhinduranya hejuru yibikoresho. Ibinyuranye na byo, bifite imitwe minini, iringaniye, cyangwa izunguruka iracyagaragara iyo umugozi umaze gukomera. Iyo isura ya screw idahangayikishije kandi biremewe cyangwa ari ngombwa gukoresha imitwe isohoka cyangwa yazamuye, imitwe ya screw idasubirwaho ikoreshwa. Iyi miyoboro isanzwe ikoreshwa mubwubatsi, gukora ibyuma, hamwe na progaramu ishyira imbere imbaraga, kuramba, hamwe nibikorwa kuruta ubwiza.
