Pali kusiyana kuwiri pakati pa mabawuti ndi zomangira:
1. Maboti nthawi zambiri amafunika kugwiritsidwa ntchito limodzi ndi mtedza. Zopangira zingwe zimatha kumenyedwa mwachindunji pamatrix a ulusi wamkati;
2. Maboti amafunikira kumenyedwa ndi kutsekedwa ndi mtunda wolimba, ndipo mphamvu yotseka ya zomangira ndi yaying'ono.

Mukhozanso kuyang'ana poyambira ndi ulusi pamutu.
Pamutu pali grooves angadziŵike ngati zomangira lalikulu ndi kubowola mchira waya, monga: mawu poyambira, mtanda poyambira, mkati hexagon, etc., kupatula hexagon akunja;
Zomangira zokhala ndi ulusi wakunja wamutu womwe umayenera kuyikidwa ndi kuwotcherera, ma riveting ndi njira zina zoyikira ndi zomangira;
Ulusi wa screw ndi wa mano ogogoda, mano amatabwa, mano otsekera katatu ndi a zomangira;
Ulusi wina wakunja ndi wa mabawuti.

Kusiyana kwa ntchito pakati pa zomangira ndi mabawuti

Bolt:
1. Chomangira chokhala ndi magawo awiri, mutu ndi wononga (silinda yokhala ndi ulusi wakunja), yomwe idzagwirizane ndi nati kuti imangirize ndikugwirizanitsa magawo awiri ndi mabowo. Kulumikizana kwamtunduwu kumatchedwa kulumikizana kwa bawuti. Ngati mtedzawo sunasinthidwe ku bawuti, magawo awiriwa amatha kupatukana, kotero kulumikizana kwa bawuti kumakhala kwa kulumikizana komwe kumatha.
2. Makina opangira makina amagwiritsidwa ntchito makamaka polumikiza kulumikiza pakati pa gawo lomwe lili ndi dzenje mu ulusi wamkati ndi gawo lomwe lili ndi dzenje podutsa. Ulusi waukulu wobowola sufuna kufananitsa nati (mtundu woterewu umatchedwa screw connection komanso ndi cholumikizira; Ukhozanso kuikidwa ndi nati womangira pakati pa magawo awiri ndi mabowo. Zomangira zimagwiritsidwa ntchito kwambiri kukonza malo achibale pakati pa magawo awiri.
3. Zomangira zokha: zofanana ndi zomangira zamakina, koma ulusi womwe uli pa screw ndi wa zomangira zapadera zodziwombera. Amagwiritsidwa ntchito pomangirira ndi kulumikiza ziwalo ziwiri zopyapyala zachitsulo kuti zikhale zonse. Mabowo apangidwe mwa mamembala zisanachitike. Chifukwa cha kuuma kwakukulu kwa zomangira, zimatha kukulungidwa mwachindunji m'mabowo a mamembala kuti apange ulusi wamkati wofananira m'mabowo a mamembala.
4. Zomangira zamatabwa: zimafanananso ndi zomangira zamakina, koma ulusi womwe uli pa screw ndi wa matabwa apadera, omwe amatha kukhomeredwa mwachindunji mu membala wamatabwa (kapena gawo) kuti amangirire gawo lachitsulo (kapena losakhala lachitsulo) kupyola bowo kupita kwa membala wamatabwa. Kulumikizana kwamtunduwu kumachotsedwanso.
