Stainless hlau screws, galvanized thiab npib tsib xee-plated screws nyob rau hauv kawg yuav ua li cas paub qhov txawv

Txhua tus siv cov ntsia hlau tsis tu ncua, feem ntau yog rau kev sib koom ua ke thiab fastening ntau qhov chaw. Qhov tseeb, screws kuj tau muab faib ua ntau hom: bolts, screws, studs, tshuab screws, tapping screws, washers, pins, rivets, kho rings, thiab lwm yam, yog tias koj tsis paub yuav ua li cas muaj ntau yam?

Screws muaj twist tshem tau ntsia liaj qhov rooj thiab cov txiv ntoo ua ke, nrog rau hom rivet, hom rivet yog ruaj khov thiab feem ntau tsis tuaj yeem rov qab siv dua, lossis bolts thiab txiv ntseej siv ntau dua. Txawm hais tias cov screws ruaj khov los yog disassembled, qhov tseeb, yuav ntsib qee qhov oxidation, corrosion thiab lwm yam teeb meem, feem ntau yog siv cov txheej txheem electroplating los daws, cia peb saib cov txheej txheem electroplating sib txawv muaj cov txiaj ntsig zoo li cas, yuav ua li cas kom paub qhov txawv.

Qhov feem ntau intuitive yog kom paub qhov txawv ntawm cov xim:

Stainless hlau yog thawj xim ntawm hlau. Galvanized screws yog dawb, xim thiab dub. Nickel-plated screws yog nyiaj.

1, stainless hlau screws yog stainless hlau khoom, stainless hlau xim yog cov hlau thiab carbon alloy, yog li cov xim yog ze rau cov xim hlau;

2, galvanized screws nto galvanized dawb zinc, xim zinc, dub zinc, thiab lwm yam, yog li xim ntawm galvanized screws feem ntau yog dawb, xim, dub;

3. Cov xim ntawm cov nickel-plated screws muaj feem xyuam rau cov npib tsib xee, feem ntau qhia cov nyiaj ci heev.
