Mutu wa countersunk mtanda bawuti ndi conical ndipo akhoza kwathunthu ophatikizidwa pamwamba pa ogwirizana mbali kukhalabe yosalala maonekedwe (muyezo GB/T 68). Zipangizo zodziwika bwino ndi chitsulo cha kaboni, chitsulo chosapanga dzimbiri kapena mapulasitiki aumisiri (monga nayiloni 66), okhala ndi malata kapena utoto wachilengedwe pamwamba.

Mutu wa countersunk mtanda bawuti ndi conical ndipo akhoza kwathunthu ophatikizidwa pamwamba pa ogwirizana mbali kukhalabe yosalala maonekedwe (muyezo GB/T 68). Zipangizo zodziwika bwino ndi chitsulo cha kaboni, chitsulo chosapanga dzimbiri kapena mapulasitiki aumisiri (monga nayiloni 66), okhala ndi malata kapena utoto wachilengedwe pamwamba.

Maboti a U ali ndi ulusi kumapeto onse awiri, ndipo amagwiritsidwa ntchito kukonza zinthu zozungulira monga mapaipi ndi mbale (standard JB/ZQ 4321). Zodziwika bwino ndi M6-M64, zopangidwa ndi chitsulo cha kaboni kapena chitsulo chosapanga dzimbiri, chokhala ndi malata kapena chakuda.

T-bolt ndi bawuti yokhala ndi mutu wooneka ngati T, wogwiritsidwa ntchito ndi T-slot (wokhazikika DIN 3015-2), ndipo mawonekedwe a flange amawonjezera malo olumikizana nawo ndipo amatha kupirira mphamvu yakumeta ubweya wammbuyo. Zodziwika bwino ndi M10-M48, makulidwe 8-20mm, ndi chithandizo chapamwamba cha phosphating chokana dzimbiri.

10.9S Torsion Shear Bolts ndi mabawuti amphamvu kwambiri opangira zida zachitsulo. Kutsitsa kumayendetsedwa ndikupotoza mutu wa maula kumchira (standard GB/T 3632). Seti iliyonse imakhala ndi mabawuti, mtedza, ndi ma washers, omwe amafunikira kupangidwa mumtanda womwewo kuti atsimikizire kusasinthika kwazinthu zamakina.

10.9S mabawuti akulu a hexagon ndizomwe zimalumikizana ndi mikangano yamphamvu kwambiri. Amapangidwa ndi mabawuti, mtedza, ndi ma washer awiri (standard GB/T 1228). Mphamvu yamakokedwe imafika 1000MPa ndipo mphamvu zokolola ndi 900MPa. Chithandizo chake chapamwamba chimatengera ukadaulo wa Dacromet kapena multi-alloy co-lopenya, ndipo kuyesa kwa kupopera mchere kumaposa maola 1000. Ndizoyenera kumadera ovuta kwambiri monga nyanja zamchere komanso kutentha kwambiri.

Mtedza wowotcherera ndi mtedza wokhazikika ku chogwirira ntchito powotcherera. Mitundu yodziwika bwino imaphatikizapo mtedza wowotcherera (DIN929) ndi mtedza wowotcherera (DIN2527). Mapangidwe ake amaphatikizapo gawo la ulusi ndi zitsulo zowotcherera. Malo owotcherera ali ndi bwana kapena ndege kuti awonjezere mphamvu zowotcherera.

Mtedza wakuda wamphamvu kwambiri ndi mtedza womwe umapanga filimu yakuda ya Fe₃O₄ oxide pamwamba pazitsulo za alloy kupyolera mu mankhwala oxidation (mankhwala akuda). Zinthu zoyambira nthawi zambiri zimakhala 42CrMo kapena 65 manganese chitsulo. Pambuyo pozimitsa + chithandizo cha kutentha, kuuma kumatha kufika HRC35-45.

Mtedza woletsa kumasula ndi mtedza womwe umalepheretsa mtedza kumasuka kudzera mu mapangidwe apadera.

Mtedza wamtundu wa zinki umadutsa pamaziko a electrogalvanizing kuti apange filimu yamtundu wa utawaleza (yokhala ndi trivalent chromium kapena hexavalent chromium) yokhala ndi makulidwe a filimu pafupifupi 0.5-1μm. Kuchita kwake kotsutsana ndi dzimbiri ndikwabwinoko kuposa electrogalvanizing wamba, ndipo mtundu wapamtunda ndi wowala, ndi magwiridwe antchito komanso kukongoletsa.

Mtedza wa electrogalvanized ndi mtedza wodziwika kwambiri. Zinc wosanjikiza waika pamwamba pa mpweya zitsulo kudzera njira electrolytic. Pamwamba pake ndi zoyera za silvery kapena bluish white, ndipo zimakhala ndi anti-corrosion ndi ntchito zokongoletsa. Mapangidwe ake amaphatikizapo mutu wa hexagonal, gawo la ulusi, ndi galvanized layer, zomwe zimagwirizana ndi GB / T 6170 ndi zina.

Electroplated galvanized flange nati ndi mtedza wapadera wokhala ndi flange wozungulira womwe umawonjezeredwa kumapeto kwa nati wa hexagonal. Flange imawonjezera malo okhudzana ndi magawo ogwirizana, imabalalitsa kupanikizika ndikuwonjezera kukana kukameta ubweya. Kapangidwe kake kumaphatikizapo gawo la ulusi, flange ndi galvanized layer. Mitundu ina imakhala ndi mano oletsa kutsetsereka pamwamba pa flange (monga DIN6923 standard).
