Impumyi zihumye zikoreshwa mu nganda nk'imyenda n'inkweto. Imirongo ihanamye ikozwe kuva mu mwobo kugeza ku mutwe hashingiwe ku gice cya kabiri. Bitewe n'uburemere bwabyo n'umutwe wimisumari idakomeye, bikoreshwa mukuzunguruka ibikoresho bitari ibyuma bifite umutwaro muke.
Imirongo idakunze gukoreshwa mu nganda nk'imyenda n'inkweto,aho ibice bikomeye bigomba gusubirwamo no gukoreshwa muguhuza ibikorwa biremereye. Akenshi usanga ari ibintu bitandukanijwe, kandi igice cya hollow rivets ikoreshwa cyane. Impera ya karuvati (ifite umurambararo muto wumurizo) imisumari ikozwe mu nsinga zikomeye kandi irashobora kwinjira mu byuma byerekana uburebure bwa 0.5mm bitabaye ngombwa ko habaho umwobo.
Imirongo ntishobora kugororwa cyangwa guhindurwa, kandi ikoreshwa cyane mubisanduku byibanga, agasanduku k'urugendo, no mu mifuka ya gisirikare, imirongo ya Hollow (igice cya hollow rivets) ikorwa hifashishijwe insinga zoroshye kandi mubisanzwe bisaba ko zidashobora gucika nyuma yo kuzunguruka. Hariho ubwoko bwinshi bwa rivets, kandi ubu ibikinisho bimwe na bimwe byatangiye gukoresha imisumari iciriritse cyangwa imisumari yumwana na nyina kugirango isimbuze ibiti kumunini munini, bishobora kugabanya cyane ibiciro byumusaruro. Gukurura ibice hamwe nibice byingenzi bikoreshwa cyane mugukoresha ibikoresho byoroshye kandi byoroshye, hamwe nibisabwa bidakenewe. Ibikoresho byo gukora mubusanzwe bikozwe mubikoresho bifite plastike nziza.
Imirongo ya mbere yari ibiti bito bikozwe mu biti cyangwa amagufwa, kandi imibiri ya mbere yo guhindura ibyuma irashobora kuba abakurambere b'imirongo tuzi uyumunsi. Nta gushidikanya, ni bwo buryo bwa kera buzwi bwo guhuza ibyuma n'abantu, guhera mu gihe cyo gukoresha ibyuma byoroshye. Kurugero, mugihe cya Bronze, Abanyamisiri bakoresheje imirongo kugirango bahambire imiterere itandatu yimbaho yimbaho kumirongo yinyuma yibiziga byerekanwe hamwe. Abagereki bamaze gutera ibishusho binini mu muringa, bakoresheje imirongo kugira ngo bazunguze ibice bitandukanye hamwe.
Imirongo idahwitse ihimbwa ahanini hagamijwe gukora cyangwa gusana ibikoresho bya harness. Ntabwo bisobanutse neza igihe havumbuwe imirongo yubusa, ariko ibikoresho byavumbuwe hagati yikinyejana cya 9 cyangwa icya 10 nyuma ya Yesu. Ibikoresho byanyeganyega, nk'inono ifite imisumari, yabohoye imbata imirimo ivunanye. Rivets kandi yatumye habaho ibintu byinshi byavumbuwe, nkibikoresho byuma bikoreshwa nabakozi bumuringa nicyuma hamwe nintama yintama yintama.
Mu 1916, igihe HV White wo mu ruganda rukora indege mu Bwongereza yabonaga bwa mbere ipatanti y’impumyi zishobora kuzunguruka ku ruhande rumwe, abantu ntibatekerezaga ko imirongo nk'iyi izakoreshwa cyane muri iki gihe. Kuva mu kirere kugera ku mashini zo mu biro, ibicuruzwa bya elegitoroniki, n'ibikoresho bya siporo, dushobora kuvuga ko iyi rivet yahumye yabaye uburyo bwiza bwo guhuza imashini.
