Qhov Ntau Thiab Tsawg Ntawm Tus Kheej Tapping Screws Rau Ntoo (20 Duab): Dub Thiab Daj Tus Kheej Tapping Screws, Lub Rooj Ntawm Lawv Qhov Ntau Thiab Tsawg. Yuav Xaiv Qhov Ntev Ntaw

Thaum ua tiav kev kho, ua kom tiav thiab tsim kho, nrog rau kev tsim cov rooj tog zaum, tshwj xeeb fasteners tau siv - ntoo ntsia hlau. Lawv qhov ntau thiab tsawg thiab xaiv qhov haum tshaj plaws li cas - nyeem kab lus.

Txuj

Qhov ntau thiab tsawg ntawm tus kheej tapping ntsia hlau thoob ntiaj teb tau ntsuas hauv ob qhov ntau - qhov ntev thiab txoj kab uas hla. Lawv cov shank muaj cov xov xov tsis tiav thiab yam ntxwv tus kheej tapping tsawg dua.

Qhov ntev ntawm cov ntoo ntsia hlau raug ntsuas raws li GOST 1144-80, 1145-80, 1146-80.

Qhov ntev ntawm ntau hom

Rau kev ua haujlwm nrog ntoo, khawm nrawm nrog cov xov tsis tshua muaj siv . Nws yog cov qauv no uas pab tsis puas fastened qhov chaw. Tsis tas li, cov kws ua haujlwm qee zaum pleev cov khoom siv nrog cov roj kom yooj yim ntswj thiab txo qhov kev puas tsuaj ntawm ntoo. Kuj tseem muaj ob qhov pib lossis sib txawv xov suab - nws tau siv rau cov khoom siv nrog cov qauv ntom. Hauv cov ntoo tawv thiab tuab, yuav luag txhua lub qhov rau nws tus kheej tapping screws tau xyaum ua ntej. Qhov no yog ua kom cov txheej txheem mus nrawm dua. Rau hom mos, muaj lwm qhov laj thawj: yog tias cov ntsia hlau raug teeb tsa ze rau ntawm ntug, qhov npaj tau npaj yuav tiv thaiv cov khoom tawg.

Cov khoom siv los ua tus kheej tapping screws yog carbon hlau, stainless hlau thiab tooj dag. Fasteners ua los ntawm cov pa roj carbon yog nrov dua, lawv muaj tus nqi qis thiab, nrog rau txoj kev xaiv raug, yuav nyob ntev. Tom qab qee yam kev ua tiav, kho vajtse tau txais nws tus kheej xim.

• Dub … Tau txais los ntawm cov txheej txheem oxidation - qhov no yog cov tshuaj tiv thaiv redox, vim tias cov yeeb yaj kiab oxide tseem nyob ntawm cov khoom, lossis los ntawm cov txheej txheem ntawm phosphating, thaum txheej txheej tsis zoo hauv cov zinc, hlau lossis manganese phosphates tau tsim rau saum npoo..
• Daj - tau txais thaum lub sijhawm txheej txheem anodizing, qhov no yog cov tshuaj tiv thaiv hluav taws xob, thaum lub sijhawm cov yeeb yaj kiab oxide tsim rau saum npoo.
• Dawb - cov no yog cov khoom siv galvanized.

Los ntawm hom kawg, cov fasteners yog ntse los yog nrog ib tug laum … Cov ntse yog tsim los rau cov khoom siv mos, thiab cov uas muaj lub laum yog rau cov khoom siv ntom ntom lossis rau cov hlau tuab dua 1 hli. Kuj tseem muaj kho vajtse thiab tsis muaj qhov xaus, siv hauv kev sib dhos ntawm rooj tog. Kev ntsuas qhov ntev ntawm cov khawm nrawm nyob ntawm hom thiab qhov loj ntawm qhov txuas nrawm. Daim ntawv qhia loj yog loj heev thiab suav nrog ntau dua 30 hom. Qhov ntev ntawm cov khoom sib txawv los ntawm 13, 16, 20, 25, 30, 35, 40, 45, 50, 60, 70, 80, 90, 100, 110 thiab mus txog 120 hli. Cov ntsia hlau sab nraud sab nraud hauv hli - 1.6, 2.0, 2.5, 3.0, 4.0, 5.0, 6.0, 8.0 thiab 10.0.

Tus kheej tapping ntsia hlau yuav tsum ntev li ntev tau kom nws tuaj yeem hla mus rau thawj ntu thiab mus rau qhov thib ob tsawg kawg ib lub hlis twg (lossis ntau dua) ntawm nws cov tuab . Xws li lub roob tuaj yeem hu ua txhim khu kev qha. Qhov tsawg tshaj plaws tus kheej tapping ntsia hlau rau ntoo kuj tseem hu ua noob, vim lawv cov duab zoo li cov noob paj noob hlis. Tus kheej tapping screws rau txuas cov phab ntsa ntub dej sib txuas yog cov khawm me me, rau lawv qhov loj lawv hu ua "kab". Ua galvanized nrog tus ntoo khaub lig. Nyob rau sab nraum qab ntawm lub taub hau muaj cov zawj rau txhawm rau txhawm rau ntswj ntsia hlau. Qhov loj ntawm txoj kab uas hla yog 3.5 mm, thiab qhov ntev ntawm tus pas nrig yog 9.5 thiab 11 mm.

Countersunk taub hau thiab ncaj qhov

Siv rau ntu uas yuav tsum haum ua ke kom haum. Nws tsis tas yuav tsum tau ua ntej laum cov grooves, txij li qhov tshwj xeeb zoo ntawm lub taub hau tso cai rau kho vajtse kom tiav "nkag" tsob ntoo. Kev so rau lub cuab yeej ntawm lub taub hau yog qhov qhib. Nws tuaj yeem ncaj, cruciform, tiv thaiv kev ua phem, hexagonal.

Lawv tau siv hauv kev tsim cov rooj tog thiab rau sheathing.

Daj thiab dawb hla recessed

Daj thiab dawb (lwm yam xim) tus kheej tapping screws tau siv rau kho ntau qhov chaw rau ntoo nrog kev npaj ua ntej ntawm qhov . Tiv taus cov txheej txheem corrosion. Rau kev tsim khoom, cov hlau mos tau siv, cov khoom tiav yog galvanized. Tus kheej tapping ntsia hlau muaj qhov ntse kawg thiab lub taub hau taub hau. Feem ntau, cov qhov rooj txuas nrog cov khoom siv no.

Hex taub hau

Zoo heev rau tus txheem ntsia liaj qhov rooj, nta cov xov xov dav thiab ua kom pom tseeb dua … Rau cov ntsia hlau, siv cov yuam sij 10, 13 thiab 17 mm. Feem ntau siv thaum ua haujlwm nrog cov khoom siv rau lub ru tsev, txhawm rau kho cov ntsiab lus ntawm lub laj kab, thiab lwm yam .… Hex fasteners feem ntau yog nruab nrog cov roj hmab tshwj xeeb gaskets rau kev sib khi.

Nrog xovxwm tshuab ntxhua khaub ncaws

Lawv qhov sib txawv tseem ceeb yog lub taub hau dav thiab tiaj tus, nyob ntawm ntug uas muaj qhov tshwj xeeb nthuav tawm rau qhov ua kom zoo dua ntawm qhov chaw … Nws muaj ntau yam kev siv dav, haum rau hlau, yas, plywood, fiberboard. Daim phiaj seem ntawm kho vajtse nrog lub tshuab ntxhua khaub ncaws me me, txhua tus muaj tib txoj kab uas hla - 4.2 hli. Qhov ntev yog los ntawm 13, 16, 19, 25, 32, 38, 41, 50, 57 txog 75 mm . Heev feem ntau muaj qhov tsis zoo tus kheej tapping screws ntawm lub khw. Koj tuaj yeem paub qhov txawv ntawm lawv los ntawm lub hau - nws tau sib npaug thiab yuav luag tiaj tus, raws li, lub qhov yog ntiav. Cov hlau ntawm cov khoom no tsis tau ua tiav hauv txhua txoj kev thiab tuaj yeem khoov lossis tawg thaum ua haujlwm. Txawm tias nws tus kheej tapping screws nrog zinc txheej sai sai thiab corrode, txij li txheej galvanized yog nyias heev. Tsis tas li, qhov loj ntawm txoj kab uas hla ntawm cov fasteners tuaj yeem yog 3.8-4.0 tsis txhob tshaj tawm 4.2.

Qhov zoo ntawm tus kheej tapping screws yog qhov kev txiav txim siab ntau dua. Lawv lub hau tau ua nyob rau hauv daim ntawv ntawm trapezoid thiab muaj qhov tob, nthuav tawm qhov. Lawv kuj tuaj yeem raug hu ua txhawb nqa. Cov cuab yeej no xa lub zog zoo dua.

Yuav xaiv li cas?

Thaum xaiv tus kheej tapping screws rau ntoo, tsis txhob nyob ntawm cov hlau lossis cov ntsia hlau thoob ntiaj teb. Cov cuab yeej nqaim-profile yuav tuav ua ke cov qauv ntoo zoo dua, thiab cov khoom siv thoob ntiaj teb yog qhov zoo tshaj plaws rau kev koom nrog cov hlau thiab cov ntoo. Ua ntej koj yuav tsum xaiv hom taub hau taub hau, lub ntsiab lus tseem ceeb ntawm no yog kev sib txuas uas yuav tsum tau ua. Ntxiv mus, hom ntawm qhov. Hom nrov tshaj plaws hauv lub taub hau yog TORX. Lawv nqa lub zog zoo tshaj plaws los ntawm cov cuab yeej.

Hom xov - thoob lub hau ntswj lossis tsis yog. Txhawm rau txuas ob ntu ntoo, kho vajtse nrog cov xov tsis tiav yog qhov tsim nyog. Qhov ntev yuav tsum sib haum rau qhov loj ntawm lub hauv paus kom raug ntsia hlau . Muaj thaj tsam tsis muaj xov nyob hauv qab taub hau, thiab ua tsaug rau nws, muaj qhov sib haum ntawm cov khoom siv rau ib leeg. Txhawm rau txhawm rau txhawm rau ntswj rau hauv cov ntoo tuab, nws raug nquahu kom siv cov ntsia hlau uas muaj lub zeb los yog zeb. Tsuas yog kho vajtse nrog cov xov tsis tiav cov xov xov tau nruab nrog nws. Nws suav nrog ntau qhov zawj nyob ntawm qhov pib ntawm xov. Lawv pab kom "muag" cov ntoo saum npoo av.

Nws yog qhov yuav tsum tau them sai sai rau qhov loj ntawm txoj kab uas hla thiab ntev ntawm cov ntsia hlau qws txhawm rau tiv thaiv kev tawg ntawm ntoo thaum ua haujlwm . Lub ntsiab lus tseem ceeb yog qhov xov los ntawm qhov twg, nws yuav tsum yog los ntawm qhov kawg. Ib lub voj nyob deb deb qhia tias qhov kawg tsis yog taw qhia thiab tsis meej. Ua haujlwm nrog cov fasteners yuav ua rau muaj teeb meem ntau.

Kev xaiv xim kuj nyob ntawm cov khoom siv uas yuav ua haujlwm. Rau ntoo, cov ntsia hlau nws tus kheej tapping yog qhov zoo tshaj, tab sis lawv muaj tus nqi siab dua . Cov ntsia hlau dub muaj tus lej tsis zoo: lawv raug rau xeb, thiab cov xim tuaj yeem tshwm sim ntawm cov ntoo. Qhov no tsis yog qhov tseem ceeb rau cov hlau, vim tias daim ntawv cog lus tuaj yeem pleev xim rau. Tsis tas li, cov cuab yeej dub yog qhov tsis yooj yim - yog tias koj ntswj lawv, lub kaus mom yuav tawg. Ib qho piv txwv yuav yog flooring. Cov laug cam zoo li qhuav thiab khoov, vim qhov no, lub nra ntawm tus kheej tapping ntsia hlau nce, lub taub hau tawg. Yog li ntawd, hauv pem teb ntoo pib creak.

Yog tias muaj cov khoom siv hlau hauv qhov txuas, zinc-coated tus kheej tapping screws yuav ua. Nws kuj tseem tsim nyog txiav txim siab yuav ua li cas kho vajtse yuav raug ntsia rau hauv lub qhov npaj los lossis tsis.
