Dacromet-Coated Hex Qhov (socket) Lub taub hau hau Screws DIN 912 Standard

2026-08-17 IB

Daim Ntawv Qhia Txog Kev Tshaj Tawm ntawm Dacromet Surface Treatment thiab Socket Head Cap Screw Specifications

1. Taw qhia

Dacromet-coated hex qhov (socket) lub taub hau hau hau screws ua raws li DIN 912 tus qauv sawv cev rau kev ua tau zoo fastening kev daws teeb meem uas sib txuas cov tshuab ua tau zoo ntawm precision-engineered socket taub hau hau screws nrog superior corrosion kuj ntawm Dacromet nto kho. Cov fasteners no tau siv dav hauv tsheb, kev tsim kho, marine, cua zog, thiab kev siv tshuab ua haujlwm uas ob qho tib si kev ncaj ncees thiab kev tiv thaiv corrosion mus ntev yog qhov tseem ceeb.

Kab lus no muab cov ncauj lus kom ntxaws ntxaws los ntawm ob qhov kev xav: Dacromet txheej txheej txheem, uas muab cov fasteners no tshwj xeeb los tiv thaiv corrosion, thiab DIN 912 socket head cap screw geometry, uas txhais lawv cov qauv tsim thiab cov qauv.

2. Dacromet Txheej Technology

Dacromet yog ib qho kev tshaj lij, dej-raws li, ib puag ncig tus phooj ywg los tiv thaiv corrosion txheej tshuab tsim los ua lwm txoj hauv kev siv tshuaj electroplating. Nws yog ib qho uas tsis yog-electrolytic dip spin txheej txheej txheej txheej txheej ntawm ultra-fine zinc flakes, aluminium flakes, chromic acid tebchaw, thiab tshwj xeeb organic binders. Thaum kho ntawm qhov kub thiab txias, cov khoom no tsim ib txheej tuab, ntau txheej txheej hlau uas khi metallurgically rau cov hlau substrate.

Tsis zoo li cov pa electroplating, uas tso siab rau electrolytic deposition, Dacromet ntiav cov txheej txheem dip-spin lossis dip-drain. Cov fasteners yog raus rau hauv Dacromet kua txheej, ces centrifuged kom tshem tawm cov khoom ntau dhau, thiab thaum kawg ci ntawm kwv yees li 300 degrees Celsius. Txoj kev kho no ua rau cov zinc thiab txhuas flakes rau laminate thiab sinter ua ke, tsim cov nyiaj-grey, muaj kev tiv thaiv zoo heev.

Cov txheej txheem Dacromet txheej txheem muaj ntau yam kev tswj xyuas kom zoo:

Kauj ruam	Txheej txheem	Kev piav qhia
1	Degreasing	Kev tshem tawm cov roj, lubricants, thiab cov khoom paug tawm ntawm qhov chaw siv cov tshuaj ntxuav alkaline
2	Txhaj tshuaj tiv thaiv	Mechanical tu kom tshem tawm nplai, xeb, thiab oxide txheej los ntawm qhov chaw fastener
3	Dip-Spin Txheej	Immersion hauv Dacromet kua txheej ua raws li centrifugal spinning los tswj txheej thickness
4	Thawj Curing	Ci ntawm 80-120 degrees Celsius kom evaporate noo noo thiab tsim thawj zaj duab xis
5	Thib Ob Dip-Spin	Kev xaiv thib ob txheej txheej rau txhim kho corrosion tiv thaiv
6	Kev kho zaum kawg	Ci ntawm 280-320 ° C rau sinter zinc / aluminium flakes thiab tsim cov txheej txheem tiv thaiv zaum kawg
7	Txias & Tshuaj xyuas	Kev tswj kom txias ua raws li kev soj ntsuam zoo rau txheej thickness, adhesion, thiab tsos

3. DIN 912 Socket Head Cap Screws

DIN 912 yog German Industrial Standard uas qhia txog qhov ntev, kam rau ua, thiab txhua yam khoom ntawm hex qhov (socket head cap screws), tseem hu ua Allen bolts lossis socket head cap screws. Cov fasteners no muaj lub taub hau cylindrical nrog lub tshuab hluav taws xob hexagonal, tsim los tsav los ntawm Allen wrench (hex key). Tus qauv DIN 912 tau txais kev pom zoo thoob ntiaj teb thiab ua haujlwm zoo sib npaug rau ISO 4762.

Lub qhov (socket head cap screws) yog tus cwj pwm los ntawm lawv lub zog loj-rau-loj piv. Lub cylindrical lub taub hau tsim tso cai rau ntau dua clamping rog piv rau cov pa hex taub hau screws ntawm tib txoj kab uas hla, thaum lub sab hauv hex tsav enables installation nyob rau hauv confined qhov chaw nrog txwv clearance. Lub taub hau zaum yaug nrog los yog hauv qab ntawm qhov chaw mating thaum nruab rau hauv lub qhov counterbored, muab qhov zoo nkauj, tsis tshua muaj profile.

3.3 Mechanical Properties

DIN 912 socket head cap screws yog tsim los ntawm ntau yam ntaub ntawv thiab muaj nyob rau hauv ntau yam khoom vaj tse. Cov cuab yeej cuab tam feem ntau rau lub qhov (socket head cap screws) yog 8.8, 10.9, thiab 12.9, uas qhia tias muaj zog tensile ntau ntau.

Chav Kawm Khoom	Khoom siv	Min. Tensile zog (MPa)	Min. Yield zog (MPa)	Hardness (HRC)
8.8	Carbon Steel	800	640	22-32 : kuv
10.9	Hlau alloy	1000	900	32-39 : kuv
12.9	Hlau alloy	1200	1080	39-44 : kuv
