Hexagonal self-drilling screws, tsim los ntawm Hebei Wotu Fastener Manufacturing Co., Ltd., ua haujlwm raws li kev lag luam niaj hnub thiab tswj nruj me ntsis raws li ISO9001: 2015 qhov system zoo. Lub tuam txhab siv "Wotu" ua nws lub npe lag luam.
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.
