Lo lus "tus qauv" hauv Suav teb yog luv luv rau "tus qauv fasteners," lub ntsiab lus nqaim. Cov txheej txheem siab- thiab nruab nrab-siab xa mus rau ib hom fastener uas tuaj yeem tiv taus qee qhov siab thiab siv rau hauv qhov chaw tshwj xeeb. Lub tswv yim ntawm high- thiab nruab nrab-siab tus qauv qhov chaw rau dig muag rivets. Lo lus "tus qauv" hauv Suav teb yog luv luv rau "tus qauv fasteners," lub ntsiab lus nqaim.
