Triangular tambo dzinonyanya kushandiswa pakubatanidza, nepo rectangular, trapezoidal uye serrated tambo dzinonyanya kushandiswa kutapurirana;Zvinoenderana neinotungamira helix, yakakamurwa kuita shinda-kuruboshwe uye kurudyi-kurudyi, kazhinji-kurudyi shinda;Zvinoenderana nenhamba yehelix, inogona kukamurwa kuita shinda imwe chete, kaviri shinda uye tambo yakawanda;Kubatana kunowanzoita waya imwe chete, uye kutapurirana iwaya mbiri kana waya yakawanda;Zvinoenderana nehukuru hwemazino, inogona kukamurwa kuita shinda yakaoma uye shinda yakanaka.Zvinoenderana nenguva dzakasiyana dzekushandisa uye mabasa, inogona kukamurwa kuita yekusimbisa tambo, pombi tambo, yekufambisa tambo, yakakosha tambo, nezvimwe.
Mune cylindrical thread, triangular tambo ine yakanaka yekuzvivharira kuita.Yakakamurwa kuita mazino akakasharara nemazino akanaka.Kazhinji, tambo dzakakora dzinoshandiswa kubatanidza.Mazino akanaka ane gomo diki, kona diki inosimuka uye zvirinani kuzvivharira kuita.Iwo anowanzo shandiswa muzvikamu zvidiki, dzakatetepa-madziro machubhu, vibration kana kusiyanisa mutoro wekubatanidza uye yakanaka-tuning zvishandiso.Mutambo wepombi unoshandiswa pakubatana kwakasimba kwepombi fittings.Rectangular shinda ine hunyanzvi hwepamusoro, asi inowanzotsiviwa neshinda yetrapezoidal nekuti haisi nyore kugaya uye inonetsa kupinza nepakati pemukati nekunze.Mupendero wekushanda weshinda yakatsetseka iri padyo nerectangular yakatwasuka, iyo inonyanya kushandiswa kutakura unidirectional axial force.
Zino fomu re conical shinda ine triangular, iyo inonyanya kuenderana nekushanduka kwezino kuti ive nechokwadi chekusimba kwetambo mbiri.Inonyanya kushandiswa kugadzira pombi fittings.
Zvinoenderana nekusimba, inogona kupatsanurwa kuita shinda yakavharwa uye isina kuvharwa shinda.
