Lub teeb steel qauv yog ib tug hluas thiab tseem ceeb steel qauv system. Nws tau siv dav hauv kev lag luam, kev ua liaj ua teb, kev lag luam, thiab kev pabcuam vaj tsev. Nws kuj tau siv los ntxiv cov plag tsev, hloov pauv, thiab txhawb nqa cov vaj tsev qub, thiab hauv thaj chaw tsis muaj cov khoom siv hauv tsev thiab hauv thaj chaw uas muaj kev thauj mus los tsis yooj yim. Lub sijhawm tsim kho nruj thiab cov tsev txav tau yooj yim thiab tshem tawm tau zoo heev los ntawm cov tswv. Ib qho khoom siv tseem ceeb rau peb thaum tsim cov qauv hlau no yog laum-tailed self-tapping screws. Yog li koj paub ntau npaum li cas txog tus kheej tapping screws?

"Self-drilling screws" kuj hu ua "drilling screws", "drilling screws", "self-drilling screws", kuj hu ua "dovetail screws", Lus Askiv: SELF DRILLING SCREWS. Nws cov qauv siv suav nrog lub teb chaws tus qauv GB / T 15856.1-2002, German tus qauv DIN7504N-1995, thiab Japanese tus qauv JIS B 1124-2003.

Cov ntsia hlau zoo li no muaj lub laum lub taub hau, uas yog lub npe tom qab lub taub zoo ib yam li lub laum twist. Thaum lub sij hawm sib dhos, cov ntsia hlau tuaj yeem laum tawm qhov chaw nruab nrab ntawm nws tus kheej, thiab tom qab ntawd siv cov xov uas nyob ib sab mus rau nws tus kheej tapping thiab extruding cov ntsia hlau sib txuam hauv lub qhov ntawm cov cab kuj. Xov, yog li nws yog hu ua self-drilling thiab tapping screws.

Raws li cov qauv siv, laum tail screws tuaj yeem muab faib ua: lub teb chaws tus qauv GB / T, German standard DIN, Japanese standard JIS, thiab thoob ntiaj teb tus qauv ISO.

Nws tseem tuaj yeem muab faib ua pawg hauv qab no raws li kev siv thiab cov duab:

1. Hla recessed lauj kaub taub hau nws tus kheej-drilling thiab tapping screws. Hla recessed lauj kaub taub hau drilling screws nrog tapping ntsia hlau xov Implementation standard: GB/T 15856.1-2002 muaj cov nram qab no specifications: (tseem hu ua round head laum tail).

2. Hla recessed countersunk taub hau self-drilling thiab tapping screws. Hla recessed countersunk taub hau drilling screws nrog tapping ntsia hlau xov Kev siv tus qauv: GB / T 15856.2-2002 muaj cov lus qhia hauv qab no: (tseem hu ua lub taub hau taub hau, lub taub hau laum tail).

3. Hexagon flange taub hau drilling screws nrog tapping ntsia hlau xov. Kev siv tus qauv: GB / T 15856.4-2002. Nws muaj cov lus qhia hauv qab no: (tseem hu ua hexagonal Dahua laum tail, uas yog ib qho ntawm cov laum tail screws. Qhov feem ntau siv thiab loj tshaj specification.)
