Tili ndi zida zotsogola kwambiri, mainjiniya odziwa bwino ntchito komanso ogwira ntchito, odziwika bwino amasamalidwe kachitidwe kabwino komanso ochezeka ndi odziwa bwino omwe amapeza ndalama zothandizira zisanachitike/zogulitsa za High Quality China Heavy Hex Structural Bolt ndi Nut ( ASTM A325/A490), Chiyembekezo choyamba! Chilichonse chomwe mungafune, tiyenera kuchita zonse zomwe tingathe kuti tikuthandizeni. Timalandira ndi manja awiri makasitomala ochokera padziko lonse lapansi kuti agwirizane nafe kuti tithandizire.
Tili ndi zida zotulutsa zamakono kwambiri, mainjiniya odziwa bwino ntchito komanso ogwira ntchito, odziwika bwino amasamalidwe kachitidwe kabwino komanso ochezeka omwe amapeza ndalama zothandizira asanagulitse.China Hex Head Bolt, Kapangidwe ka Hex Bolt, Khazikitsani ubale wabizinesi wanthawi yayitali komanso wopambana-wopambana ndi makasitomala athu onse, gawanani zopambana ndikusangalala ndi chisangalalo chofalitsa zinthu zathu padziko lonse lapansi. Tikhulupirireni ndipo mupindula zambiri. Onetsetsani kuti muzitha kulumikizana nafe kuti mudziwe zambiri, tikukutsimikizirani kuti timasamala nthawi zonse.
ASTM A325 / A325M Heavy Hex Structural Bolts

Ma bolts amapangidwa kuti agwiritsidwe ntchito polumikizana ndi zomangamanga. Malumikizidwewa akukhudzidwa ndi zofunikira za Specification for Structural Joints Kugwiritsa Ntchito Maboti a ASTM A325, ovomerezedwa ndi Research Council on Structural Connections, ovomerezedwa ndi American Institute of Steel Construction ndi Industrial Fastener Institute.

Kukula: ASME B18.2.6 (Inchi Kukula), ASME B18.2.3.7M (Metric Kukula)

Kukula kwa Ulusi: 1/2″-1.1/2″, M12-M36, ndi utali wosiyanasiyana

Kulongedza: Chochuluka pafupifupi 25 kgs katoni iliyonse, makatoni 36 aliwonse phale

Ubwino: Ubwino Wapamwamba ndi Kuwongolera Kwabwino Kwambiri, Mtengo Wopikisana, Kutumiza munthawi yake; Thandizo laukadaulo, Malipoti a Supply Test

Chonde khalani omasuka kulankhula nafe kuti mumve zambiri.

Mu 2016, ASTM A325 idachotsedwa mwalamulo ndikusinthidwa ndi ASTM F3125, pomwe A325 tsopano imakhala giredi pansi pa F3125. Mafotokozedwe a F3125 ndikuphatikiza ndikusintha miyezo isanu ndi umodzi ya ASTM, kuphatikiza; A325, A325M, A490, A490M, F1852, ndi F2280.

Isanatulutsidwe mu 2016, mawonekedwe a ASTM A325 anali ndi ma bolt amphamvu kwambiri a hex kuchokera pa 1/2 ″ m'mimba mwake mpaka 1-1/2 ″. Mabotiwa amapangidwa kuti azigwiritsidwa ntchito polumikizana ndi kamangidwe kotero amakhala ndi ulusi wamfupi kuposa ma bawuti wamba a hex.

Izi zimagwira ntchito pamaboti olemetsa a hex okha. Pamaboliti amasinthidwe ena ndi kutalika kwa ulusi wokhala ndi makina amakina ofanana, onani Specification A449.

Maboti ogwiritsira ntchito wamba, kuphatikiza mabawuti a nangula, amaphimbidwa ndi Specification A449. Onaninso Specification A449 yazitsulo zozimitsidwa ndi zitsulo zozimitsidwa ndi zitsulo zokhala ndi ma diameter akulu kuposa 1-1/2 ″ koma zokhala ndi makina ofanana.
