Uyu munsi tuzavuga uburyo tugomba guhitamo ingano ya rivet yuzuye,
Mugihe ukeneye imirongo, ikintu cyingenzi nuguhitamo diameter D ya shell ya rivet hamwe nuburebure L bwigikonoshwa.1. Itegereze neza neza aho dukoresha.Mubisanzwe hitamo diameter ntoya kurenza aperture.Niba diameter ya rivet ari nini cyane, bizagerwaho nkigisubizo, rivet ntishobora kwinjizwa.Niba diameter ya rivet ari nto cyane, bizatera ubunebwe.Mubisanzwe, ntoya 0.1-0.2MM irakwiriye.2. Itegereze ubunini bwikurikiranya.Ubunini bwikoreshwa bugomba kuba munsi yuburebure bwigituba.Ibipimo birashobora kugereranwa nimbonerahamwe ikurikira kugirango uhitemo ibisobanuro bya rivet.
Kurugero, aperture ni 3.3MM naho ubunini ni 3MM.Kuva kumeza dushobora kubona neza ko tugomba guhitamo D 3.2MM-L7MM
Inzira D * L = 3.2 * 7MM ya aluminium ibyuma
