Countersunk Head Phillips Self Drilling Screws

Muaj ntau ntau hom winged self-drilling screws, tab sis lawv txhua tus muaj cov yam ntxwv zoo ib yam. Muaj tsib yam ntxwv tseem ceeb. Cov khoom kho mob hauv qab no qhia txog tsib yam ntawm winged self-drilling screws:

1. Feem ntau ua los ntawm carburized steel (99% ntawm tag nrho cov khoom). Kuj tseem siv tau rau cov hlau tsis muaj hlau lossis cov hlau tsis muaj hlau.

2. Self-drilling screws nrog tis yuav tsum tau kho cua sov. Kho vajtse qhia rau koj tias carbon steel self-tapping screws yuav tsum tau carburized, thiab stainless hlau nws tus kheej tapping screws nrog tis rau tes yuav tsum yog cov khoom hardened. Txhawm rau ua kom tus kheej tapping screws ua tau raws li cov khoom siv kho tshuab thiab kev ua haujlwm yuav tsum tau ua los ntawm tus qauv.

3. Winged self-drilling ntsia hlau cov khoom muaj siab hardness thiab zoo core toughness. Ntawd yog, "mos rau sab hauv thiab muaj zog rau sab nraud". Cov khoom siv kho mob qhia rau koj tias qhov no yog ib qho tseem ceeb ntawm kev ua haujlwm ntawm tus kheej-drilling tis rau tes. Yog hais tias qhov saum npoo hardness tsawg, nws tsis tuaj yeem ntsia hlau rau hauv matrix; Yog hais tias lub hauv paus tsis zoo toughness, nws yuav tawg sai li sai tau thaum nws yog screwed rau thiab siv tsis tau. Yog li ntawd, "soft sab hauv thiab nruj sab nraud" yog tus kheej-drilling screws nrog tis rau tes kom ua tau raws li qhov yuav tsum tau ua.

4. Qhov saum npoo ntawm Qhov Zoo Tshaj Plaws Drilling Screw Nrog tis cov khoom xav tau kev kho qhov chaw tiv thaiv, feem ntau electroplating kho. Cov khoom siv kho mob qhia rau koj tias qhov chaw ntawm qee cov khoom yuav tsum tau kho nrog phosphate (phosphating). Piv txwv li: Self-drilling screws nrog tis ntsia hlau rau ntawm phab ntsa yog feem ntau phosphated
