An M20 Hex nati chisungiso chine hexagonal chakajairwa kubatirana neM20 bhaudhi, chine 20mm metric thread diameter. Inowanzo gadzirwa kubva kabhoni simbi kana simbi isina tsvina, inonamatira kune dzimwe nyika zviyero seDIN 934, ISO 4032, uye ASTM A194. Aya nzungu akakosha mune inorema-basa dhizaini, mota, uye maindasitiri mashandisirwo uko yakakwirira tensile simba uye vibration kuramba kunodiwa. Sourcing kubva kumugadziri ane certification inovimbisa chaiyo kushivirira kweshinda, inowirirana giredhi rezvinhu, uye yakavimbika pamusoro pekurapa kwekudzivirira ngura.
Chii chinonzi M20 Hex Nut? Madiro Ehunyanzvi uye Maitiro
Iyo M20 hex nut chinhu chakakosha mukusangana kwemichina, yakagadzirirwa kuchengetedza majoini pasi pemutoro wakakura. “M” inoreva chimiro cheshinda yemetric, ukuwo “20” ichidudza dhayamita rekunze reshinda mumamilimita. Kunzwisisa tekinoroji nuances yeiyi fastener kwakakosha kune mainjiniya, nyanzvi dzekutenga zvinhu, uye mamaneja ekuvaka vanoisa pamberi pekuvimbika kwechimiro.
Key Dimensional Parameter
Kuti M20 nut ishande nemazvo, inofanirwa kusangana nekushivirira kwakasimba. Kutsauka kunogona kutungamirira kukukurura shinda, kushandisa torque zvisina kufanira, kana kutadza kubatana. Zviyero zvekutanga zvinosanganisira:
- Nominal Diameter (d): 20 mm. Iyi ndiyo dhayamita huru yeshinda yemukati.
- Thread Pitch (P): Iyo yakajairwa coarse pitch yeM20 ndeye 2.5 mm. Misiyano yepitch yakanaka (semuenzaniso, M20x1.5 kana M20x2.0) iripo yezvishandiso zvine hunyanzvi zvinoda kunyatsojeka kana kuramba kuzunguzika.
- Upamhi Mhiri KwemaFlats (s): Kazhinji 30 mm kune akajairwa anorema hex nzungu, achibvumira kuenderana neakajairwa wrench saizi.
- Urefu (m): Inosiyana nerudzi. Standard hex nuts (DIN 934) inowanzova nehurefu hunosvika 18 mm, nepo nzungu dzakatetepa dzichipfupika, uye dzinorema hex nzungu dzakareba kuti dzipe mamwe shinda.
