Qib 8.8 yog dab tsi?
Qib 8.8 Bolts yog tsim los siv nruab nrab carbon steel uas tau raug quenched thiab tempered. Lub npe "8.8" qhia qhov tsawg kawg nkaus tensile lub zog ntawm800 MPathiab yield zog piv ntawm0.8. Siv rau hauv cov khoom siv tsheb ciav hlau, lub cev muaj zog, lub cav thiab cov khoom siv ua haujlwm, qib 8.8 bolts nthuav tawm lub zog tensile zoo thiab ua tau zoo nyob rau ntau qhov chaw. Lawv tsis ua haujlwm zoo nyob rau hauv ib puag ncig uas muaj qhov kub thiab txias.
Vim tias muaj ntau ntau qib sib txawv thiab cov fasteners tag nrho saib txog tib yam, cov qib nruab nrab carbon thiab alloy steel lub zog yog cim rau kev txheeb xyuas. Bolts thiab screws kuj dais lub cim los txheeb xyuas cov chaw tsim khoom. Yog tias lub zog tseem ceeb, xyuas kom meej tias ob qho tib si qib thiab cov chaw tsim khoom muaj cov cim qhia.

Qhov hnyav -hex-bolt yog dab tsi?
Heavy Hex Bolts yog tsim los siv rau ntau yam kub, siab zog muaj kev siv, xws li steel fabrication thiab dav siv. Lawv muaj lub taub hau tuab dua li tus qauv lossis cov hex bolts tsis tu ncua, thiab muab cov kabmob loj dua uas faib cov clamping load hla thaj tsam dav dua. Hnyav hex bolts tuaj yeem ua nrog ob peb yam khoom sib txawv xws li qis thiab nruab nrab carbon steel, alloy, thiab stainless hlau, thiab muaj cov dawb, kub dipped galvanized, phosphate, zinc lossis cadmium plated. Qee qhov ntau thiab tsawg ntawm hex bolts yog tag nrho threaded thaum lwm qhov ntau thiab tsawg muab lub xub pwg du.
Heavy Hex Bolt Specifications
General hnyav hex bolts suav nrog ASTM A307 specifications, uas npog carbon steel bolts thiab studs xws li 1/4 "mus txog 4" inch. Qhov no yog qhov hnyav tshaj plaws hex ntsia liaj qhov rooj thiab suav nrog Qib A, B, thiab C uas qhia txog lub zog tensile, kev teeb tsa, thiab nws txoj kev siv.
