Structural Kutendeseka:Heavy heavy structural bolts inoenderana neASTM A325 uye ASTM A490 inogadzirwa kuti ipe yakasarudzika kuvimbika mukuda kuvaka uye mapurojekiti ezvivakwa. Aya mabhaudhi akagadzirirwa kukurira mitoro yakakwira uye kushushikana, zvichiita kuti ive yakakodzera kune yakakosha kunyorera uko kuchengetedzeka uye kuvimbika kwakakosha.

Simbi Yakasimba:Yakagadzirwa kubva kune yakakwirira-yakasimba simbi alloys, aya mabhaudhi anopa epamusoro tensile uye shear simba zvivakwa, kuve nechokwadi chekuita kwakavimbika mukubatana kwemaitiro. Kuvakwa kwavo kwakasimba kunoita kuti zvive zvakanaka kuti zvishandiswe mumabhiriji, zvivakwa, shongwe, uye zvimwe zvivakwa zvinotakura zvinotakurwa zvinorema uye masimba ane simba.

Weather Resistance:Heavy hex structural bolts akagadzirirwa kurwisa zvakatipoteredza zvinhu zvakaita sekuora, ngura, uye mamiriro emuchadenga. Iine mabhaudhi asingadziviriri uye zvigadzirwa, mabhaudhi aya anopa kugara kwenguva refu uye kuvimbika, kunyangwe munzvimbo dzakaomarara dzekunze uye kushandiswa kwemugungwa.

Preload uye Clamping Force:Nekupa yakakwira mwero we preload uye clamping simba, ASTM A325 uye A490 mabhaudhi anobatsira kuchengetedza kubatana kuperera uye kudzivirira kusunungura pasi pemitoro ine simba uye vibrations. Izvi zvinovimbisa kuti zvigadziriso zvinongedzo zvinoramba zvakachengeteka nekufamba kwenguva, zvichideredza njodzi yekutadza kwemaitiro uye kuve nechokwadi chekuchengetedzwa kwevashandi nemidziyo.

Kutevedzera uye Certification:Sezviyero zveindasitiri, anorema hex zvimiro mabhaudhi anoedzwa kwakasimba uye chitupa kuti ave nechokwadi chekutevedzera ASTM A325 uye A490 zvakatemwa. Izvi zvinosanganisira kuyedzwa kwemakanika, kuongororwa kwemakemikari, uye macheki ekuona mashandiro uye kutendeseka kwemabhoti, ichipa vimbiso yemhando uye kuvimbika.

Zvinotarisirwa pakuiswa:Maitiro ekuisa akakodzera, anosanganisira echokwadi ekusimbisa maitiro uye bhaudhi pretensioning, zvakakosha kuti uwedzere kuita kweanorema hex mabhaudhi echimiro. Kutevera kurudziro yevagadziri uye maindasitiri akanakisa maitiro anovimbisa yakakwana bhoti kuita uye kurongeka kwehunhu.

Kuonana Nenyanzvi:Kana uchitsanangura mabhaudhi anorema ehex emapurojekiti ekuvaka, kubvunza mainjiniya ezvimiro uye nyanzvi dzekusimbisa zvinokurudzirwa. Ivo vanogona kupa nhungamiro pakusarudza iyo chaiyo bhaudhi mhando, saizi, uye giredhi kuti isangane nezvinodiwa zvechishandiso uye kuve nechokwadi chekutevedzera indasitiri zviyero.

Zvakakosha Zvikumbiro:Heavy hex structural bolts zvinhu zvakakosha muzvikamu zvekuvaka uye zvivakwa, kwaanoita basa rakakosha mukuona kuchengetedzeka uye kugadzikana kwenzvimbo dzakavakwa. Kubva kumabhiriji uye zvivakwa kuenda kumaindasitiri ezvivakwa uye zvifambiso zvekufambisa, mabhaudhi aya anobatsira mukusimba kwechimiro uye kusimba kwemapurojekiti akakosha ezvivakwa.
