Mitundu yosiyanasiyana ya bolt
Kusiyanitsa pakati pa mabawuti ndi zomangira kuli mbali ziwiri: imodzi ndi mawonekedwe, gawo la bawuti limafunikira kwambiri kuti likhale lozungulira, lomwe limagwiritsidwa ntchito poyika nati, koma gawo la screw nthawi zina limakhala la conical kapena ngakhale nsonga; ina ndi Kugwiritsa ntchito ntchitoyo, wononga wononga mu chandamale zinthu m'malo nati. Nthawi zambiri, mabawuti amagwiranso ntchito payekhapayekha, ndipo amakhomeredwa mwachindunji mu dzenje lobowoledwa kale, popanda kufunika kwa nati kuti agwirizane nawo. Panthawiyi, bawutiyo imayikidwa ngati screw potengera ntchito.
Mawonekedwe ndi cholinga cha mutu wa bawuti amagawidwa kukhala ma bawuti ammutu a hexagonal, mabawuti ammutu akulu, ma bawuti amutu ozungulira theka, mabawuti amutu, ma bolts okhala ndi mabowo, T-mutu mabawuti, mbedza mutu (maziko) mabawuti ndi zina zotero.
Ulusi wa mzati ukhoza kugawidwa mu ulusi wolimba, ulusi wabwino ndi ulusi wa inchi, choncho umatchedwa bolt yabwino ndi inchi bolt.
Njira Yopanga
Choyamba, nkhonya yoyamba imasuntha kukonza waya kuti apange, ndiyeno nkhonya yachiwiri imasuntha kuti ipangenso wayayo ndikuumba chinthu chomalizidwa. Pamutu wozizira, kufa kokhazikika (kuponderezedwa kufa) ndi kupondaponda (kuphwanyidwa) kufa (kukhomerera)
Chiwerengero cha mitu) sichifanana. Zitsulo zina zovuta zingafunike nkhonya zingapo kuti zipange palimodzi, zomwe zimafuna zida zamitundu yambiri kuti zipangitse screw. Kugudubuza ulusi ndi kugwiritsa ntchito zida ziwiri zozungulira zozungulira (mbale zopaka) zokhala ndi mano opindika kuti afinyize chopanda kanthu chopangidwa ndi ma multi-station kapena makina otsogolera pakati.
Pambuyo pamutu ndi kusisita mano, zowononga zonse zapangidwa. Zoonadi, kuti mawonekedwe a screw awoneke bwino komanso abwino, njira yochiritsira pamwamba nthawi zambiri imachitika. Monga kuyeretsa ndi passivation wa zosapanga dzimbiri zomangira zitsulo, electroplating padziko mpweya zitsulo zomangira, etc. Anapanga mitundu yosiyanasiyana ya zomangira wononga.
