Aob -end studyog ib tug fastener threaded ntawm ob qho tag nrho nrog ib tug du shank nyob rau hauv nruab nrab, feem ntau yog siv los txuas ob yam. Nws cov specifications ua raws li cov qauv tsim nyog, thiab cov kev tsis sib xws tau teev tseg hauv qab no:
Txoj kab uas hla: Txoj kab uas hla ntawm ob -kawg stud feem ntau yog cim hauv millimeters (mm) lossis nti, xws li M6, 1/4 nti, thiab lwm yam.
Length: Qhov ntev ntawm ob -kawg stud hais txog qhovtag nrho ntevntawm cov ntsia liaj qhov rooj (xov ntawm ob qho kawg ntxiv rau nruab nrab shank), feem ntau qhia hauv millimeters lossis nti, xws li 25 hli, 1 nti, thiab lwm yam.
Khoom siv: Ob chav-kawg studs tuaj yeem ua los ntawm carbon steel, stainless hlau, alloy steel thiab lwm yam ntaub ntawv, xaiv raws li qhov chaw pabcuam tiag tiag thiab kev ua haujlwm.
Xov hom: Cov xov ntawm ob npaug - kawg studs suav nrog metric threads thiab unified inch threads, feem ntau suav nrog metric M series, UNC (Unified Coarse) series, UNF (Unified Fine) series, thiab lwm yam.
Chav kawm khoom vaj khoom tsev: Cov chav kawm ntawm ob chav - kawg stud sawv cev rau nws lub zog txhua yam. Cov chav kawm feem ntau yog 8.8, 10.9, 12.9, thiab lwm yam. Cov chav kawm siab dua, qhov ntau dua lub zog thiab kev thauj khoom ntau dua -cov kabmob muaj peev xwm.
Nco ntsoov tias qhov tseeb specifications ntawmob -end studsyuav tsum ua raws li cov qauv hauv lub tebchaws (xws li GB / T 901, GB / T 897, thiab lwm yam). Rau kev xaiv, thov xa mus rau cov qauv tsim nyog lossis sab laj cov kws tshaj lij raws li qhov xav tau tiag tiag.
Cov kev txwv hauv qab no kuj tseem yuav raug txiav txim siab thaum txiav txim siab ob npaug -end stud specifications:
Xov hom: Ntxiv nrog rau metric thiab ntiv tes xov, cov xov tshwj xeeb xws li cov xov tapered thiab cov yeeb nkab xov yuav siv tau raws li qhov xav tau.
Xov ntev: Qhov no yog hais txog cov xov ntev ntev ntawm ob qho kawg ntawm cov stud, muaj nyob rau hauv qhov sib npaug -ntev thiab tsis sib npaug- ntev tsim. Nws tuaj yeem hloov kho rau kev sib dhos kom ntseeg tau tias muaj kev sib koom tes thiab kev sib txuas.
Kev kho deg: Txhawm rau txhim kho corrosion thiab zoo li qub, ob npaug -kawg studs tuaj yeem ua rau saum npoo- kho nrog galvanizing, npib tsib xee plating, Dacromet, thiab lwm yam. Kev kho cua sov yog txheej txheem los txhim kho lub zog, tsis yog kev kho deg.
Anti-loosing configuration: Ob chav-end studs tsis muaj ua-hauv kev tiv thaiv-loosing qauv. Rau kev tiv thaiv-loosing daim ntawv thov, txuam fasteners xws lixauv ceevthiab lub caij nplooj ntoos hlav ntxhua khaub ncaws tuaj yeem siv tau.
Cov kev qhia tshwj xeeb ntawm ob npaug -end studs yuav tsum tau txiav txim siab raws li daim ntawv thov tshwj xeeb thiab cov kev xav tau sib dhos kom tau raws li kev nyab xeeb thiab kev ua tau zoo ntawm kev sib txuas. Rau cov qauv tshwj xeeb lossis cov kev xav tau, xa mus rau cov qauv kev lag luam sib xws lossis sab laj cov kws tshaj lij kom paub meej thiab raug cov ntaub ntawv.
