Nekuti iyo hafu yezino screw ine chikamu chemwenje tsvimbo, uye nzvimbo yemwenje yemwenje inoenderana nechikamu cheshinda, ine gomba rakagara rakaiswa padhuze, kugadzikana kwekuvhara kwakakwira, uye mukuita kwesimba rekugera, kureba kwechinhu iyo fastener kashoma kuchinja.Kana chinhu kutsanya mhedzisiro zvinodiwa zvakanyanya kuomarara, hazvigone kuve nekesi shoma, zvinokurudzirwa kushandisa hafu zino sikuruu.Uye kusimba kwedhayamita yetsvimbo yehafu zino sikuruu yakakwirira kudarika siruu yezino rose, uye simba regoho rakati wedzerei zvishoma.Kana pane chinodiwa chesimba re screw, zvinokurudzirwa kusarudza hafu zino.
Iine tekinoroji seyakakosha, gadzira uye gadzira zvigadzirwa zvemhando yepamusoro zvinoenderana nezvinodiwa zvakasiyana zvemusika.Iine pfungwa iyi, kambani icharamba ichigadzira zvigadzirwa zvine yakawedzera hunhu uye inoramba ichivandudza zvigadzirwa, uye ichapa vatengi vazhinji zvigadzirwa uye masevhisi akanakisa!
Kutora pfungwa huru ye "kuva Mutoro".Isu tichadzokorodza nzanga kune zvigadzirwa zvemhando yepamusoro uye sevhisi yakanaka.Tichatanga kutora chikamu mumakwikwi epasi rose kuti tive vekutanga-kirasi kugadzira chigadzirwa ichi munyika.
