Qhia koj yuav ua li cas xaiv cov ceev ceev

1. Cov khoom lag luam (tus qauv)
Lub tshuab luam ntawv lub npe yog cuam tshuam nrog nws cov qauv thiab cov xwm txheej siv tau. Rau fasteners uas ua raws cai tshwj xeeb, sau npe tus lej ntawm tus qauv tuaj yeem cuam tshuam lawv cov qauv thiab kev ua tau zoo. Thaum tsis muaj cov qauv ntshiab, cov khoom tsis yog-txheem (cov qauv tsis yog) yuav tsum muaj cov duab kos kom piav qhia txog lawv qhov ntev thiab cov duab.
2. Cov lus qhia tshwj xeeb
Qhov tshwj xeeb ntawm cov fasteners feem ntau muaj ob ntu: txoj kev uas hla ntawm cov xov thiab qhov ntev ntawm cov ntsia hlau. Cov metric thiab Asmeskas lub tshuab yog ob lub ntsiab cov ntsiab lus tseem ceeb. Metric Screws xws li M4-0.7X8 sawv cev rau ib xov sab nraud ntawm 4 hli, 0.7 sawv cev suab, thiab 8 sawv cev ncaj qha ntev. Miskas cov ntsia hlau xws li 6 # -32 * 3/8, nyob qhov twg 6 # sawv cev rau sab nraud txoj xov ntev, thiab 3/8 yog qhov ntev ntawm cov ntsia hlau.
3. Cov Khoom Siv
Cov khoom ntawm cov fasteners txiav txim siab lawv lub zog, corrosion tsis kam, thiab kev pabcuam lub neej. Cov ntaub ntawv nquag muaj cov hlau, hlau hlau, tooj liab, thiab lwm yam tshuaj ntsuab, thiab cov roj carbon hlau, cov pa roj carbon ntau, thiab cov hlau aluminoy. Nws yog qhov tseem ceeb los xaiv cov khoom tsim nyog raws li daim ntawv thov cov xwm txheej thiab kev ua tau zoo.
4. Lub zog qib
Yog rau cov pa roj carbon stackenters, muaj lub zog ua rau lawv lub zog tensile thiab kom muaj zog. Cov qib ntau xws li 4.8, 5.8, 8.8, 12.9, 12,9, feem ntau yuav tsum tau kho thiab kub cua sov kom lawv cov khoom siv.
5. Nto Kho
Cov kev kho deg yog feem ntau yog tsom rau kev nce cov corrosion tsis kam thiab kev ua kom zoo nkauj ntawm lub fasteners. Cov txheej txheem kev ua xws li muaj kev sib daj sib xyaw, xws li xiav thiab dawb plaw, chrome lub plating tsim nyog cov kev pabcuam lub neej ntawm lub neej fasteners.
