Lub taub hau hex yog ib lub taub hau nrog lub taub hau hexagonal uas tuaj yeem nruj nrog ib tug ciaj ntswj ( ciaj ntswj) los yog lub qhov (socket), uas koom rau sab nrauv ntawm lub taub hau hex. Cov hom fasteners no muaj lub taub hau sab nraud thiab yuav tsum tsis txhob tsis meej pem nrog lub taub hau hex lossis lub qhov (socket) -- tom kawg muaj lub qhov (socket) sab hauv uas tuaj yeem tsav nrog lub hex me ntsis los yog ciaj ntswj.
Ib tug ntsia hlau yog ib tug neeg kho tshuab fastener nrog ib tug threaded ncej uas haum ncaj qha mus rau hauv ib feem. Lo lus hex taub hau ntsia hlau feem ntau yog hais txog tshuab screws nrog pre-fabricated tshuab threads. Tshuab screws zoo ib yam li bolts, tab sis lawv feem ntau yog threaded thoob plaws hauv lub ncej.
Ntoo screws thiab self-tapping screws kuj qee zaum muaj lub taub hau hex thaum xav tau lub zog siab. Txawm li cas los xij, ntoo screws thiab self-tapping screws muaj tapered shafts nrog ntse threads tsim los txiav mating threads nyob rau hauv qhov chaw lawv fastening.
Qee lub taub hau hex taub hau muaj slotted los yog Phillips taub hau thiab tus qauv hex taub hau kom lub hau ntswj tuaj yeem siv tau thaum lub dab teg lossis lub qhov (socket) tsis muaj lossis tsis yooj yim. Qhov no tuaj yeem hu ua kev sib xyaw ua ke.
Hex taub hau screws yuav muaj tag nrho cov kabmob taub hau, taub hau ntxhua khaub ncaws, lossis flanged taub hau nrog cov tshuab ntxhua khaub ncaws. Lawv muaj nyob rau hauv galvanized steel, galvanized steel, organically coated steel, stainless hlau, bronze, nylon los yog bi-hlau.
Hex taub hau ntsia hlau tsim los ua phooj ywg nrog lub tshuab xov, tseem hu ua hex taub hau ntsia hlau, teeb ntsia hlau, los yog tshuab ntsia hlau, yog siv los tiv thaiv ib qho khoom hauv lossis rau lwm yam khoom.
American National thiab Unified Standard Heavy Hex thiab Hex Cap Screws, ANSI/ASME B18.2.1-1996, qhia tau hais tias qhov loj zoo tagnrho rau cov ntsia hlau yog 0.25–3 nti (6.35–76.20 mm) hauv txoj kab uas hla.
Qee hom ntawm cov ntsia hlau no yog tsim los siv rau lawv tus kheej qhov (tseem hu ua lag screws lossis tus kws qhia screws) thiab feem ntau siv rau:
txuas ntoo hnyav lossis khoom siv rau ntoo
Khaws cov khoom hnyav rau masonry
Ruaj ntseg cov khoom teeb rau ntoo lossis hlau.
Cov hom hex taub hau screws muaj qhov taw tes tapered uas tuaj yeem yooj yim tso rau hauv lub qhov tsav lossis lub nylon ntsaws, taw tes taw qhia tsim los tho ntoo lossis lub teeb ntsuas hlau, lossis lub laum me ntsis tsim los txav ntoo.
Self-drilling hex taub hau los yog Tek screws rau kev koom nrog hlau rau hlau. Cov hom hex taub hau fasteners no muaj cov lus qhia grooved uas nws tus kheej xyaum thaum ntsia, tshem tawm qhov xav tau rau lub qhov pilot.
Self-drilling hex taub hau screws muaj cov ntsiab lus ntawm qhov sib txawv ntawm qhov ntev, nyob ntawm qhov tuab ntawm cov hlau uas tuav lub fastener.
