Hex qhov (socket) tiaj tus taub hau ntsia hlau DIN7991

Hex Qhov (socket) tiaj tus taub hau ntsia hlau 9-1

DIN7991 countersunk hexagon socket ntsia hlau, lub taub hau yog conical, nruab nrab yog ib tug recessed hexagon, lub taub hau ntsia hlau yuav embedded nyob rau hauv lub mounting nto tom qab installation, lub nto yog du thiab zoo nkauj. Lub taub hau ntawm countersunk hexagon socket ntsia hlau tuaj yeem muab tso rau hauv cov khoom siv, thiab tuaj yeem siv lub zog loj dua, thiab kev sib txuas lub zog siab dua. Nws tuaj yeem hloov lub hexagon socket bolt. Feem ntau siv nyob rau hauv cov qauv ntawm compact, du tsos ntawm cov leeg. DIN7991 hexagon socket countersunk taub hau ntsia hlau yog ib qho kev siv rau German tus qauv DIN7991-1986, uas qhia cov xov specification los ntawm M3 - M24 ISO metric xov, khoom qib A hexagon socket countersunk taub hau ntsia hlau.

DIN7991 hexagon socket countersunk taub hau screws muaj nyob rau hauv carbon steel thiab stainless hlau. Cov qib kev ua tau zoo ntawm carbon steel hexagon socket countersunk taub hau screws yog 8.8, 10.9, 12.9, tus qauv tuaj yeem xa mus rau GB3098.1. Cov ntaub ntawv carbon steel feem ntau xav tau kev kho deg, feem ntau yog oxidation, electroplating, xws li kev xav tau rau lwm yam txheej txheej los yog kev kho deg, kuj tuaj yeem sib tham. Stainless hlau hexagon socket countersunk taub hau screws feem ntau siv nyob rau hauv kev ua lag luam yog ua los ntawm SUS304 thiab SUS316, stainless hlau khoom corrosion kuj thiab kub kuj muaj zog. SUS304 nruab nrab ua haujlwm hardening tus nqi, haum rau kev ua haujlwm txias thiab ncab; Qhov CORROSION RESISTANCE ntawm SUS316 yog qhov zoo dua li ntawm 304. Nws yog tshwj xeeb tsim rau Marine thiab tshuaj lom neeg tshaj tawm. Nws muaj zoo corrosion kuj thiab qhov corrosion kuj.

Hexagon socket screws tau muab faib ua cylindrical taub hau hexagon socket bolts raws li lub taub hau, uas feem ntau siv, thiab nws kuj muaj ntau yam, raws li cov khoom siv, muaj hlau, uas yog, carbon steel thiab stainless hlau. Stainless hlau hex bolts kuj muaj stainless hlau 304 thiab 202 thiab lwm yam khoom siv. Semi - puag ncig lub taub hau hex socket bolt, qhov no kuj tau hu ua lauj kaub taub hau hex socket bolt. Countersunk taub hau hex socket bolt, lub taub hau yog lub taub hau tiaj tus, sab hauv yog hex qhov (socket). Muaj ib hom ntawm lub teb chaws tus qauv yog tshwj xeeb tshaj yog, hu ua headless hexagon bolt. Uas yog qhov peb feem ntau hu ua 'meter' ntsia hlau, them nyiaj ntsia hlau, teeb ntsia hlau. Cov no yog cov ntsiab lus zoo rau headless hex bolts, tab sis lawv txhua tus txhais tau tib yam. Tau kawg, kuj tseem muaj qee qhov bolts nrog paj paj sab hauv hexagon taub hau. Qhov kev siv no tsawg dua, kev ua lag luam kuj tseem nyuaj rau pom. Hexagon socket ntsia hlau txawm hais tias muaj ntau yam ntawm lub teb chaws tus qauv kuj muaj ntau, tab sis yeej ib co tshwj xeeb tshaj, yeej muaj tsawg tus neeg yuav mus siv nyob rau hauv lub lag luam. Siv ntau los yog tus naj npawb ntawm cylindrical taub hau hex socket screws, tseem hu ua cylindrical taub hau hex socket screws.
