Cholinga cha anti-kumasula chimatheka poonjezera kukangana pakati pa ulusi kapena bolt (screw) mutu ndi nati kumapeto kwa nkhope kapena kuonjezera kukangana kwa onse awiri nthawi imodzi. Njira yotsutsa kumasulayi ndi yodalirika kwambiri kuposa njira ziwiri zomwe zili pamwambazi, koma ubwino wake waukulu ndikuti sichimachepa ndi malo ogwiritsira ntchito, akhoza kusonkhanitsa mobwerezabwereza ndi kupasuka, akhoza kusonkhanitsidwa mosinthasintha, ndi zina mwa zomangira (monga mtedza wa nayiloni wotsekera, mtedza wonse wotseka zitsulo) wafika pamlingo wodalirika kwambiri wotsutsa-loosening. Chifukwa chake, njira yotsutsa kumasulayi imagwiritsidwa ntchito kwambiri pantchito yopanga makina komanso gawo lazamlengalenga.

• Mtedza Wawiri:Njira yophatikizira mtedza wapawiri ndikumangitsa mtedza wamkati kaye, kenako kumangitsa nati wakunja, kenako ndikusinthanso nati wamkati, kuti ulusi womwe uli pakati pa utali wa mtedzawo upangitse kupindika pang'ono zotanuka kuti apeze kukangana kowonjezera kuti asamasuke. Zochita zawonetsa kuti njira yolumikizira iyi si yodalirika pakumasula nati pawiri. Choyipa chake ndi chakuti pamene mtedza wamkati umasinthidwa, ndondomeko yokhazikika imatsitsidwa, mphamvu ya clamping imakhala yaying'ono, ndipo mphamvu yotsutsa-kumasula imachepetsedwa. Njira yatsopano yochitira msonkhano imathetsa ndondomeko ya "kumangiriza kwamkati kwa mtedza wamkati", ndiko kuti, choyamba kumangitsa mtedza wamkati, ndiyeno kumangitsa mtedza wakunja, ndikugwiritsanso ntchito torque yomweyi ku mtedza awiriwo, kuti mphamvu yokhotakhota ya dongosolo lokhazikika ikhalebe pamtunda wapamwamba. Mayesero apakhomo ndi akunja awonetsa kuti mphamvu yotsutsa kumasula mtedza wawiri pogwiritsa ntchito njira yatsopano yosonkhanitsa imakula kwambiri. Mwa njira zosiyanasiyana zotsutsira zomangira zomangira ulusi, ndi imodzi mwa njira zingapo zotsutsa kumasula zomwe zimakhala ndi moyo wapamwamba wokana kugwedezeka. Ngakhale kugwiritsa ntchito mtedza awiri kumawonjezera kulemera kwake, kumakhala ndi dongosolo losavuta, labwino lotsutsa-kumasula, ndipo lingagwiritsidwe ntchito pa kutentha kwakukulu, kotero limagwiritsidwabe ntchito pazochitika zina zofunika, monga kutsutsa kumasulidwa kwa maulumikizidwe amtundu wa injini, ndi zina zotero.

• Mtedza wa Flangendi Bolts: Pansi pa nati ndi wononga mutu ndi zopindika kapena serrated. Pamene nati kapena wononga ndi zomangika, kukaniza mikangano kwaiye pakati pa kubala pamwamba ndi olumikizidwa gawo, makamaka pamene "serrations" ophatikizidwa pamwamba pa ogwirizana gawo, kutsekera ndi olimba kwambiri. Maonekedwe a dzino la kubereka pamwamba serrations ndi clamping mphamvu pa kumangitsa zimakhudza kwambiri locking ntchito. Ubale wokhazikika wa torsion-tension ndi mphamvu yotchinga yokwanira ndizofunikira kuti chomangirachi chikhalebe chotseka. Mayesero asonyeza kuti ali ndi katundu wabwino wotsutsa kumasula. Sichingagwiritsidwe ntchito ndi makina ochapira, komanso sichingagwiritsidwe ntchito polumikizana ndi ulusi womwe sungathe kupirira mphamvu zokhotakhota kwambiri kapena pomwe malo olumikizidwa amakhudzidwa ndi zokopa ndi dzimbiri. Mukamagwiritsa ntchito njira yotsutsa-kumasula, chidwi chiyenera kulipidwa pakufanana koyenera kwa kuuma. Nthawi zambiri, kuuma kwa gawo lotsekeka kuyenera kukhala kotsika kuposa kulimba kwa chomangira.

• Mtedza wa All-Metal Locking:Kumtunda kwa thupi la nati kumatsekedwa ndi mapeto osakhala ozungulira kapena mapeto otsekedwa (yotsirizirayi imatchedwanso slotted mtengo mtedza) kuti iwonongeko pang'ono ulusi. Bawuti ikakulungidwa mu nati, mapeto a mtedzawo amakulirakulira panja, ndipo kukhuthala kwa malekezerowo kumagwiritsidwa ntchito kukanikizira ulusiwo mozungulira, kuchotsa kusiyana kwa ulusi, kukulitsa kugunda kwa ulusi, ndi kutseka mwamphamvu bawuti ndi nati pamodzi. Zotsutsana ndi kumasula ndizabwino, ndipo mtedza wamtengo wapatali uli ndi ntchito yabwino yotsutsa kumasula. Mukagwiritsidwa ntchito ndi mabawuti okhala ndi ulusi wolondola kwambiri, ntchito yotsutsa kumasula imatha kuwongolera; ikagwiritsidwa ntchito ndi mabawuti okhala ndi kuuma kwapamwamba kofanana ndi kuuma kwa nati, kusonkhana mobwerezabwereza ndi moyo wautumiki wa disassembly wa kugwirizana ukhoza kusintha kwambiri. Pakati pa mtedza wokhoma zitsulo zonse, mtedza wamtengowo wotsekedwa umakhala wokhoza kuyambiranso. Itha kugwiritsidwa ntchito pagawo lililonse lolumikizana lokhazikika kupatula gawo losuntha.
