Txhim kho Corrosion Resistance
Fasteners raug rau cov huab cua thiab ua rau corrosion-xws li cov nyob rau ntawm plaub- qhov rooj sab nrauv siv moldings, underbody shields, thiab bumpers- yuav tsum tau tiv taus 480 teev yam tsis muaj xeb liab. Cov kev kho deg uas yuav tsum tau muaj yog xim dub lossis grey uas tsis yog-electrolytic zinc- txhuas txheej, feem ntau hu ua "Dacromet" kev kho. Fasteners kho nrog cov zinc no-txheej txheej txheej txheej txheej txheej muaj kev tiv thaiv corrosion zoo heev thiab tsis muaj kev pheej hmoo ntawm hydrogen embrittlement.
Product Appeal Optimization
Cov fasteners uas tseem pom tau -xws li cov rau lub liftgate latch, liftgate side bumpers, roj filling qhov rooj stopper, thiab cov rooj zaum -feem ntau undergo dub zinc plating los yog ib tug dub uas tsis yog -electrolytic zinc- txhuas txheej kev kho mob. Fasteners nrog cov xim dub ua kom pom qhov sib txawv tsawg dua rau cov khoom nyob ib puag ncig, yog li txhim kho qhov zoo nkauj tag nrho ntawm cov khoom.
Tsis txaus Fastener Engagement Length
Tom qab zawm, fasteners yuav tsum tau nthuav tawm 2 mus rau 3 threads; ua tsis tau raws li qhov yuav tsum tau muaj yog muaj kev pheej hmoo ntawm xov stripping los yog lub fastener ua tsis tau lub rooj zaum. Tsim kev hloov kho los daws qhov teeb meem no feem ntau yog hloov lub fastener nrog ib tug ntev dua los yog ntxiv ib tug counterbore rau mating tivthaiv kom txo tau nws cov phab ntsa thickness.
Qhov chaw me me ntawm Fastener Flanges
Lub mounting qhov rau lub dashboard los ua ke bolts feem ntau oversized kom haum raws li lub tsheb los ua ke kam rau ua, tsim kom muaj kev pheej hmoo tias lub hauv paus ntawv hlau qhov yuav tshwm sim; Yog li ntawd, bolts nrog cov ntxhua khaub ncaws loj yuav tsum tau siv los npog cov qhov qhib. Ib yam li ntawd, txhaj tshuaj- cov khoom siv molded- xws li cov ntaub thaiv npog hauv qab -feature oversized mounting qhov rau nqus lub cev los ua ke kam rau ua. Yog hais tias lub flange cheeb tsam ntawm lub fastener yog me me heev, nruj lub fastener tuaj yeem ua rau muaj kev ntxhov siab, ua rau cov ntaub thaiv npog yas tuaj yeem ua kom dawb, crushing, los yog tawg. Nws yog ib qho tsim nyog yuav tau xav txog kev siv cov fasteners nrog lub ntsej muag flange loj lossis kev sib xyaw ua ke loj loj; Feem ntau, lub ntsej muag flange yuav tsum tau muab ib qho - ib sab kev pab them nqi ntawm Ntau dua lossis sib npaug li 4 hli, nrog lub zog nruj ntawm Tsawg dua lossis sib npaug li 5 N·m.
Fastener Torque Decay
Thaum lub sij hawm kuaj xyuas, cov fasteners siv nyob rau hauv cov khoom xws li sab qhov rooj check straps, zawv zawg qhov rooj, thiab qhov rooj latches tau nthuav tawm torque decay. Txhawm rau daws qhov no, yuav tsum tau siv tshuaj tiv thaiv -loosing adhesive. Ib txoj hauv kev los tiv thaiv -txoj kev xoob xoob rau cov tsheb thauj khoom muaj feem xyuam nrog ua ntej- daim ntawv thov ntawm cov khoom siv yas; fasteners kho raws li qhov no feem ntau hu ua "Nylok" screws. Thaum lub sij hawm locking txheej txheem ntawm fasteners nrog sab hauv thiab sab nraud threads, lub compression ntawm engineering yas generates ib tug haib tshuaj tiv thaiv quab yuam; qhov no ua rau kom muaj kev sib txhuam ntawm cov xov, uas ua rau tag nrho - suab sib cuag thiab yog li ua tiav kev tiv thaiv -loosing muaj nuj nqi.
