DIN 933/931 Galvanized Hex ntsia liaj qhov rooj
Steel Hex taub hau ntsia liaj qhov rooj
hauj lwm yam khoom
DIN933 yog ib tug German qauv ntsia liaj qhov rooj nrog specifications ntawm M1.6 rau M52 thiab ib tug ntev ntawm 2 hli rau 200mm.
Bolts: txhua yam qhov chaw, cylindrical threaded fasteners nrog ceev. Ib hom ntawm khawm ris muaj ib lub taub hau thiab ib tug ntsia hlau (ib tug kheej kheej nrog rau lwm threads), uas yuav tsum tau muab kev koom tes nrog ib tug txiv rau khuam thiab txuas ob qhov chaw nrog los ntawm qhov. Qhov no hom ntawm kev twb kev txuas yog hu ua ib tug bolted kev twb kev txuas. Yog hais tias lub noob txiv yog unscrewed los ntawm cov ntsia liaj qhov rooj, ob qhov chaw yuav tau muab cais dua, li ntawd, lub ntsia liaj qhov rooj kev twb kev txuas yog ib tug detachable kev twb kev txuas.
Qhov sib txawv ntawm screws, bolts thiab ceev
bolts, ceev, thiab screws yog fasteners. Bolts thiab ceev yuav siv tau ua ke, thiab screws yuav siv tau nyob ib leeg. Qhov txawv ntawm ib tug ntsia liaj qhov rooj thiab ib tug txiv neej zoo nraug yog tias muaj yog ib tug polygon uas yog cov nyob ib ncig ntawm lub ntsia liaj qhov rooj, thiab lub NQHAJ yog tsuas yog tes tsho nrog rau lwm threads rau cov cylindrical ib feem.
Ntsia Hlau yog ib qho tsis yog lub npe. Nws yog ib lub general lub npe uas tsis yog-tub txawg rau threaded qhov chaw. Muaj yog tsis muaj tej lub npe nyob rau hauv kev ua lag luam.
Nyob rau hauv lub khawm ris kev lag luam, nyob rau hauv qhov tseeb, yog tsis muaj kev cai nruj heev qho uas txawv ntawm screws thiab bolts. Txawm li cas los, muaj ob txoj kev nyob rau hauv lub lag luam kom paub qhov txawv ntawm screws thiab bolts:
1. Faib raws li cov Screwing qauv. Lub thiaj li hu ua ciaj ntswj qauv hais txog mus rau qhov chaw nyob qhov twg cov ciaj ntswj yog muab tso rau hauv cov ntsia hlau / ntsia liaj qhov rooj, uas yog, nyob rau hauv ib co systems, lub externally threaded pas nrig-zoo li tus qhov chaw ntawm lub sab nraud ciaj ntswj qauv yog collectively xa mus rau raws li bolts, txwv tsis pub, tus lub puab ciaj ntswj qauv no yog hu ua ib tug ntsia hlau.
Txheej ciaj ntswj qauv: Hex lub taub hau ntsia liaj qhov rooj; Puab ciaj ntswj qauv: Hex ntsia liaj qhov rooj, thiab lwm yam Cov cuab piv txwv ntawm no yog lub fasteners nyob rau hauv Suav teb chaws qauv, xws li GB5782, GB5783 (ib tug ib nrab xov, ib tug tag nrho cov xov). Vim hais tias lawv yog cov tag nrho hexagonal lug, lawv yog cov tag nrho hu ua bolts nyob rau hauv tus txheej txheem lub npe.
2. qha raws li seb cov khoom muaj uas tsis yog-threaded pas nrig nta.
Qhov no kuj yog ib tug yawm lug siv faib txoj kev, uas feem ntau distinguishes bolts thiab screws nyob rau hauv no txoj kev. Uas yog: yog hais tias tus khoom no stems tsuas yog lub taub hau yog tag nrho cov threaded, xws qhov chaw uas hu ua screws. Conversely, yog hais tias nws muaj cov yam ntxwv xws li ib tug polished pas nrig nyob rau hauv tas li ntawd mus rau lub xov, nws yog hu ua ib tug ntsia liaj qhov rooj.
3. Ntsia Hlau yog ib tug ntau lub sij hawm.
Lub caij nyoog lus yuav tsum bolts, screws, thiab cov ntsia hlau kaus mom.
