Zambiri za ASTM zimafuna mutu wa hex womwe ndi wokulirapo kuposa mutu wamba (womaliza).Izi zikuphatikiza: A193, A320 ndi A307B.Ngakhale mabawuti a A325 ndi A490 amafunikiranso mutu wolemera wa hex, chonde onani Maboti a Structural Bolts kuti mudziwe mawonekedwe, popeza mabawutiwa ali ndi ulusi wamfupi kuposa ma bawuti olemera a hex.
Ntchito ya Heavy Hex Bolts
Maboti olemera a hex atha kugwiritsidwa ntchito pazinthu zosiyanasiyana monga matabwa, zitsulo, ndi zida zina zomangira zama projekiti monga ma docks, milatho, zomanga zamisewu yayikulu, ndi nyumba.Mabowuti olemera a hex okhala ndi mitu yopindika amagwiritsidwanso ntchito ngati mabawuti ammutu.
Mabowuti olemera a hex ndi chida chachikulu cha ma bawuti a handan haosheng, makamaka astm a325, a490,DIN6914 omwe amafunikira kwambiri komanso amagwiritsidwa ntchito pomanga monga ngalande ndi mlatho, njanji, mafuta ndi gasi, komanso mafakitale amagetsi amphepo.
Bolt Yopanga Chitsulo
Chitsulo chopangidwa ndi bawuti ndi mtundu wa bawuti wamphamvu kwambiri, komanso mtundu wa magawo wamba.Kusalaza ntchito bwino, ntchito dongosolo zitsulo, uinjiniya, kuti kusalaza zotsatira.Pazinthu zonse zachitsulo, ma bawuti azitsulo amafunikira kukhala pamwamba pa giredi 8.8, komanso giredi 10.9 ndi giredi 12.9, onse omwe ndi ma bolt amphamvu kwambiri.
Bawuti yamapangidwe achitsulo imagawidwa kukhala torsional shear mtundu wokulira kwambiri komanso bawuti yayikulu yamphamvu kwambiri ya hexagonal, bawuti yayikulu yolimba kwambiri ya hexagonal ndi yamphamvu yayikulu ya wononga wamba, ndipo bawuti ya torsional shear yolimba kwambiri ndikuwongolera kwakukulu. bawuti yolimba kwambiri ya hexagonal, kuti amange bwino.
Kupanga ma bawuti achitsulo kuyenera kulumikizidwa kaye ndikumangidwa, ndipo ma bawuti achitsulo ayenera kugwiritsa ntchito wrench yamagetsi yamtundu kapena torque chosinthika chamagetsi;Ndipo chomaliza kumangitsa zitsulo dongosolo mabawuti ndi zofunika okhwima, chomaliza kumangitsa torsion kukameta ubweya zitsulo zomangamanga mabawuti ayenera kugwiritsa ntchito torsional kukameta ubweya mtundu magetsi wrench, chomaliza kumangitsa makokedwe zitsulo dongosolo mabawuti ntchito torsional mtundu wrench magetsi.
Bawuti yayikulu yopangidwa ndi hexagon imakhala ndi bawuti imodzi, nati imodzi, ndi mawotchi awiri.
Maboti akuluakulu a hexagon pamapangidwe achitsulo.
Bawuti yachitsulo yometa ubweya wa torsional imakhala ndi bawuti, nati ndi washer.
