Phillip Drive Countersunk Self-tapping Screws
Dab tsi yog Cross recessed countersunk taub hau self-tapping screws?
Countersunk self-tapping screws yog ib hom ntsia hlau siv nyob rau hauv ntau yam fastening thiab kho daim ntaub ntawv.lawv yog tsim nyob rau hauv hardened carbon steel nrog ci zinc plated nto kho.Nws yog txawm peem rau nrog countersunk taub hau Feem ntau yog ua los ntawm stainless hlau, countersunk self-tapping screws yog yus muaj los ntawm lawv cov tho-zoo li tus taw tes.Self-tapping screws kais lawv tus kheej threads tab sis tsis muaj peev xwm xyaum los ntawm cov ntaub ntawv zoo li ib daim ntawv hlau.Hauv qhov no, tus kheej tapping screws yuav xav tau lub qhov pilot.
Loj
kho saum npoo
Nyob rau sab saum toj ntawm cov ntsiab lus tseem ceeb, cov tuam ntxhab tuaj yeem ntxiv cov txheej txheem tiv thaiv.Cov tiav no tiv thaiv corrosion ntau dua.Nov yog qee cov txheej txheem rau Countersunk self-tapping screws:
Zinc Plating
Zinc plating yog qhov twg zinc ntxiv siv ib txheej ntawm hluav taws xob.Nws feem ntau yog txheej nyias nyias uas ua haujlwm zoo dua rau kev siv sab hauv tsev.
Kub-dip Galvanization
Kub-dip galvanization ntxiv zinc, tab sis nws yog txheej txheej tob.Cov neeg tsim khoom dunk lub ntsia liaj qhov rooj nyob rau hauv molten zinc los tsim ib daim ntawv cog lus, uas ua rau lub txheej tshwj xeeb tshaj yog haum rau corrosive ib puag ncig xws li thaj chaw uas muaj av noo los yog ntsev nyob rau hauv cov huab cua.
Fluoropolymer (Xylan, Teflon, lossis PTFE) Txheej
Lub fluoropolymer txheej yog sib xyaw ntawm cov khoom uas tiv taus corrosion.Cov txheej txheem tuaj yeem tuav hauv qhov kub thiab txias txias yam tsis muaj qhov tawg.
Thermoplastic Txheej
Thawj qhov txiaj ntsig ntawm kev ntxiv cov txheej txheem thermoplastic rau U-bolts yog qhov sib ntxiv ntawm cov hlau.Hlau-on-hlau sib cuag tuaj yeem ua rau galvanic corrosion thiab cov qauv tawg.Ib txheej txheej thermoplastic ntxiv cov txheej txheem tiv thaiv nruab nrab ntawm cov yeeb nkab thiab kev txwv.
Cov txheej kuj tseem muaj qhov sib txhuam qis, uas txhais tau hais tias nws cia cov kav dej glide los ntawm U-bolt, thaum tuav cov yeeb nkab tib lub sijhawm.Qhov no txo qhov kev pheej hmoo ntawm cov kav dej tawg, kev txwv, lossis cov qauv kev txhawb nqa.
