Misomali yopangidwa ndi galvanized screw

Chifukwa cha kupindika kwa helical, misomali iyi imalumikizidwa kwambiri ku mtengo ndi mphamvu yokoka. Mphamvu yowonjezerayi imafunika kuti pakhale nyumba zofunika zopangidwa ndi matabwa, monga kusonkhanitsa ma pallet, pansi pa kusonkhanitsa, ndi denga. Kupaka misomali kumathandiza kuti igwiritsidwe ntchito m'malo okhala ndi chinyezi chambiri, chifukwa sizimakhudzidwa ndi dzimbiri ngati zakuda.

Msomali wakuda wokulungira

Misomali yokulungidwa ndi screw yomwe cholinga chake ndi kulimbitsa zinthu zamatabwa ndi zomangamanga, monga kuyala pansi, kupanga mitundu yonse ya zotengera zamatabwa zonyamulira ndi kusonkhanitsa zomangamanga zolimba. Chifukwa cha mawonekedwe ake ozungulira, misomali iyi imagwiridwa mwamphamvu kwambiri kumatabwa. Popeza misomali siikutidwa ndi zinc, tikukulimbikitsani kuigwiritsa ntchito pa ntchito yovuta kapena m'malo opanda chinyezi.
