Hex Head Self Drilling Screw Nrog EPDM Washer yog ib qho tshwj xeeb fastener. Nws muab cov kev ua haujlwm ntawm tus kheej - drilling ntsia hlau nrog cov txiaj ntsig ntxiv ntawm Ethylene - Propylene - Diene Monomer (EPDM) ntxhua khaub ncaws.
Cov ntsia hlau nws tus kheej muaj lub taub hau hex-puab, uas tso cai rau kom yooj yim zawm siv cov ciaj ntswj lossis lub qhov (socket). Nws tus kheej - drilling feature ua rau nws nkag mus rau cov ntaub ntawv xws li hlau, ntoo, lossis yas yam tsis tas yuav tsum tau ua ntej - drilling, ua tsaug rau nws cov ntse, threaded taub. Lub tshuab ntxhua khaub ncaws EPDM tau muab tso rau hauv qab lub taub hau ntawm cov ntsia hlau. EPDM yog cov roj hmab hluavtaws paub txog nws cov huab cua zoo heev, ua haujlwm ntev, thiab tiv thaiv UV hluav taws xob, ozone, thiab ntau yam tshuaj. Lub tshuab ntxhua khaub ncaws no muab lub foob tiv thaiv dej, plua plav, thiab lwm yam khoom, txhim kho kev ua haujlwm tag nrho thiab kev ua haujlwm ntev ntawm kev sib koom ua ke. Nws kuj tseem pab faib cov clamping quab yuam sib npaug, txo qhov kev pheej hmoo ntawm cov khoom puas.
Yuav siv li cas
- Khoom siv thiab qhov loj xaiv: Txiav txim siab qhov tsim nyog loj ntawm cov ntsia hlau raws li cov thickness ntawm cov khoom uas koj fastening. Xav txog cov load - bearing yuav tsum tau thiab xaiv ib tug ntsia hlau uas muaj zog txaus. Xyuas kom meej tias EPDM lub tshuab ntxhua khaub ncaws tau sib haum nrog ib puag ncig uas yuav siv cov ntsia hlau. Piv txwv li, nyob rau hauv kev siv sab nraum zoov, huab cua - resistant zog ntawm EPDM yog tshwj xeeb yog zoo.
- Kev npaj nto: Ntxuav qhov saum npoo ntawm cov khoom yuav tsum fastened. Tshem tawm cov av, roj, lossis cov khib nyiab uas tuaj yeem cuam tshuam lub hau ntswj lub peev xwm nkag mus thiab tsim kom muaj kev ruaj ntseg tuav.
- Kev teeb tsa: Muab cov ntsia hlau tso rau ntawm qhov chaw xav tau ntawm cov khoom siv. Siv lub hex - lub taub hau lub qhov (socket) los yog ciaj ntswj los pib tsav cov ntsia hlau. Siv lub zog ruaj khov thiab ruaj khov thaum tig cov ntsia hlau. Raws li cov ntsia hlau tho los ntawm cov khoom siv, EPDM lub tshuab ntxhua khaub ncaws yuav compress me ntsis, tsim kom muaj lub foob. Txuas ntxiv kom nruj kom txog thaum lub hau ntsaws ruaj ruaj, tab sis yuav tsum ceev faj kom tsis txhob overtighten, uas yuav ua rau cov khoom puas tsuaj los yog lub tshuab ntxhua khaub ncaws.
- Kev tshuaj xyuas: Tom qab kev teeb tsa, xyuas tias lub tshuab ntxhua khaub ncaws EPDM tau zaum zoo thiab tsis muaj kev puas tsuaj. Xyuas kom tseeb tias cov ntsia hlau yog nruj thiab muab kev ruaj ntseg tuav. Kev tshuaj xyuas ib ntus hauv cheeb tsam fastened, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig hnyav, kom paub tseeb tias EPDM lub tshuab ntxhua khaub ncaws tseem muab lub foob zoo.
