Muzvishandiso apo kuzununguka kana kutenderera kunogona kushanda nati yakasununguka, nzira dzakasiyana dzekukiya dzinogona kushandiswa: makiyi washer, jamu nzungu, eccentric mbiri nzungu, [1] nyanzvi inonamira shinda-yekukiya mvura yakaita seLoctite, mapini ekuchengetedza (akatsemuka mapini) kana lockwire. pamwe chete nenzungu dzakasungirirwa, kuisa naironi (nyloc nut), kana shinda dzakaita seovhari zvishoma.
Square nzungu, pamwe nemisoro yemabhaudhi, ndiyo yaive chimiro chekutanga kugadzirwa uye yaimbove yakajairika zvakanyanya nekuti yaive nyore kugadzira, kunyanya nemaoko.Nepo zvisingaite nhasi[rini?] nekuda kwezvikonzero zvataurwa pazasi zvekufarira kwenzungu dzine hexagonal, dzimwe nguva dzinoshandiswa mune mamwe mamiriro kana huwandu hwakanyanya hwe torque uye grip ichidikanwa kune saizi yakapihwa: kureba kukuru kwedivi rega rega kunobvumira spanner kuti ishandiswe nenzvimbo yakakura uye kuwedzera simba panzungu.
Chimiro chinonyanyozivikanwa nhasi chine hexagonal, nekuda kwezvikonzero zvakafanana semusoro webhaudhi: mativi matanhatu anopa granularity yakanaka yemakona kuti chishandiso chisvike kubva (chakanaka munzvimbo dzakasimba), asi akawanda (uye madiki) makona angave ari panjodzi yekutenderedzwa. off.Zvinotora chikamu chimwe chete pazvikamu zvitanhatu zvekutenderera kuwana divi rinotevera rehexagon uye kubata kuri kwakaringana.Zvisineyi, mapolygoni ane mativi anopfuura matanhatu haapi kubata kunodiwa uye maporigoni ane asingasviki mativi matanhatu anotora nguva yakawanda kuti apihwe kutenderera kuzere.Mamwe maumbirwo akasarudzika aripo kune zvimwe zvinodiwa, semapiro ekugadziridza zvigunwe uye nzungu dzenhapwa (eg macage nuts) enzvimbo dzisingasvikike.
