Maboti Amutu Osapanga dzimbiri a Square SquareTsatanetsataneDimension Table
Zofunika: Maboti a Stainless Steel Square Head
Zofunika: Zopangidwa kuchokera ku 304 zitsulo zosapanga dzimbiri, zomangira izi zimakhala ndi mphamvu zolimbana ndi mankhwala ndipo zimatha kukhala maginito pang'ono. Amadziwikanso kuti A2 chitsulo chosapanga dzimbiri.
Mtundu wamutu: Square Head.
Utali: amapimidwa kuchokera pansi pa mutu.
Mtundu wa Ulusi: Coarse Thread, Fine Thread.Coarse ulusi ndi muyezo wamakampani; sankhani zomangira izi ngati simukudziwa phula kapena ulusi pa inchi. Ulusi wabwino ndi wowonjezera-owonjezera amatalikirana kwambiri kuti ateteze kumasuka ku kugwedezeka; ulusi wowongoka, umakhala wabwino kukana.
Kugwiritsa ntchito: Pafupifupi theka la mphamvu ya zomangira zolimba zapakati, zomangira izi zitha kugwiritsidwa ntchito pomangitsa ntchito zopepuka, monga kuteteza mapanelo olowera. Mbali zazikulu zathyathyathya zimapangitsa kuti zikhale zosavuta kugwira ndi wrench ndikupangitsa kuti zisamazungulirane m'mabowo apakati.
