Cov ntaub ntawv tuaj yeem muab faib ua:

Carbon Steel 1022A, Stainless hlau 410, Stainless hlau 304.

1. Carbon steel Self Drilling Screw, 1022A. Txheem cua sov-kho cov hlau tuaj yeem siv los ua cov khoom siv rau kev tsim cov laum tail screws. Tom qab kev kho cua sov, qhov tawv tawv yog HV560-750 thiab cov tub ntxhais hardness yog HV240-450. Ordinary nto kho yog yooj yim rau xeb, muaj siab hardness thiab tsawg tus nqi.

2. Stainless hlau Self Drilling Screw, 410, tuaj yeem kho cua sov, thiab lawv cov xeb kuj zoo dua li carbon hlau, tab sis phem dua li cov hlau tsis muaj steel 304.

3. Stainless hlau Self Drilling Screw, 304, tsis tuaj yeem kho cua sov, muaj zog xeb kuj, tsis tshua muaj hardness, thiab tus nqi siab. Lawv tsuas tuaj yeem xyaum cov ntawv txhuas, cov rooj ntoo, thiab cov rooj zaum yas.

4. Bi- Hlau Self Drilling Screw, lub laum me ntsis yog ua los ntawm carbon steel, thiab cov xov thiab lub taub hau yog ua los ntawm 304 stainless hlau.

Tus tsim ntawm lub laum (Tek) tus Tsov tus tw tso cai rau tus kheej Drilling Screw / kev tsim kho hom los muab peb txoj haujlwm ntawm "drilling", "tapping" thiab "fastening" tib lub sijhawm. Nws cov tawv tawv thiab cov tub ntxhais hardness yog siab dua me ntsis ntawm tus kheej tapping screws. Qhov no yog vim qhov Self Drilling Screw / kev tsim kho hom muaj kev ua haujlwm ntxiv drilling, uas tuaj yeem txuag lub sijhawm tsim kho thiab cov nqi, yog li nws tau siv ntau hauv kev lag luam thiab kev siv lub neej txhua hnub.

Laum - tus Tsov tus tw kawg ntawm lub laum me ntsis zoo li, uas tuaj yeem ncaj qha laum qhov ntawm qhov chaw ntawm tus nrog sib ntaus.

Tapping - tus kheej tapping ib feem uas tsis yog lub laum me ntsis, uas tuaj yeem ncaj qha coj mus rhaub lub qhov los tsim cov xov sab hauv

Xauv - Tsis tas yuav tho qhov ua ntej kom ua tiav lub hom phiaj tseem ceeb ntawm cov ntsia hlau: xauv cov khoom

Yuav Siv Tus Kheej Drilling Screws li cas?

Qhov ntau yam thiab siv tau tus kheej-drilling ntsia hlau tau siv ntau xyoo los ua ib txoj hauv kev los txuas cov ntaub ntawv. Txij li thaum tus kheej-drilling screws tsis xav tau lub qhov pilot, lawv tuaj yeem txuas tau ntau yam khoom siv, uas ua rau muaj txiaj ntsig zoo thiab kev ua haujlwm zoo.

Hom thiab ntau yam ntawm tus kheej-drilling screws ua rau lawv muaj feem xyuam rau ntau yam kev tsim kho thiab fabricating kev ua haujlwm. Los ntawm kev siv cov vov tsev hlau mus rau kev ua tiav cov rooj sib txoos, tus kheej-drilling screws tau dhau los ua cov cuab yeej tseem ceeb hauv kev tsim, kev tsim, thiab kev tsim khoom.

Hauv kev ua yuam kev, ntau tus neeg ntseeg tias nws tus kheej tapping thiab nws tus kheej-drilling screws yog tib yam, thaum qhov tseeb lawv muaj qhov sib txawv. Qhov sib txawv ntawm lawv tau ua nrog lawv cov ntsiab lus. Lub ntsiab lus ntawm tus kheej-drilling ntsia hlau muaj qhov nkhaus kawg uas yog zoo li tus twist xyaum. Self-tapping screws yog piav raws li xov sib sau los yog txiav screws thiab muaj peev xwm muaj ib tug taw tes uas yog taw tes, blunt, los yog ca.
