Umutwe w'ivyuma, izwi kandi nk'igipfukisho c'impumyi canke igipfukisho c'indodo, ni igipfukisho c'umurongo w'igice kimwe-kirimwo indodo zo mu mutima. Itanga umwobo w’indodo mu bikoresho vy’amabara makeyi aho gushika ku ruhande rw’inyuma bidashoboka, ari uburyo bwiza kandi buzimvye bwo gufatanya ibihimba ataco bikeneye gusudira, gutyo bikarinda ahantu hasizwe irangi canke hakoreshejwe imbere y’igihe kandi bikarinda guhinduka kw’ibipande vy’ibikoresho vy’ishimikiro. Countersunk head rivet nuts, igaragazwa na "countersunk head", ni flush-mounting rivet nuts ikozwe n'umutwe w'igikoni wicara rwose munsi canke uringaniye n'uburebure bw'ibikoresho, bitanga umuti mwiza igihe uburebure bw'uburebure n'umutekano ari ibisabwa bihambaye cane.
Utuntu dutandukanye:
Countersunk head itanga flange y’uruzitiro, igatuma igira ahantu heza iyo imaze gushirwaho, bikaba bituma zibereye gukoreshwa aho ubwiza canke ubushobozi bw’ikirere ari ngirakamaro.
Ikoreshwa mu modoka, mu bibanza vy'ubuhinga bwa none, mu nzira z'amagariyamoshi zigenda vyihuta cane-, mu vy'ubwubatsi, mu vy'ibikoresho vyo mu nzu, no mu zindi nganda.
Iboneka mu migwi itandukanye no mu bikoresho bitandukanye.
