Ib allen ntsia hlau, tseem hu ua lub qhov (socket) lub taub hau hau ntsia hlau, yog ib hom fastener yam ntxwv los ntawm lub sab hauv hexagonal recess, tsav los ntawm ib tug allen ciaj ntswj (tseem hu ua hex key). Lawv feem ntau siv rau hauv ntau daim ntawv thov vim lawv lub zog siab, kev yooj yim ntawm kev teeb tsa, thiab kev tsim qauv compact, muab qhov huv thiab kev ua haujlwm zoo. Phau ntawv qhia no npog txhua yam los ntawm ntau hom, qhov ntau thiab tsawg, cov ntaub ntawv, mus rau cov ntawv thov zoo tshaj plaws rau allen screws.Kev nkag siab Allen ScrewsDab tsi yog ib Allen Screw?ib allen ntsia hlau, los yog lub qhov (socket head cap) ntsia hlau, yog ib lub hau ntswj nrog lub taub hau cylindrical thiab lub qhov (socket) hexagonal uas tau tsav los ntawm ib qho allen ciaj ntswj los yog hex key. Kev tsav tsheb sab hauv tso cai rau lub zog siab dua piv rau cov slotted lossis Phillips taub hau screws, ua rau lawv tsim nyog rau cov ntawv thov uas yuav tsum tau muaj zog thiab txhim khu kev qha fastener.History ntawm cov Allen ScrewCov allen ntsia hlau tau tsim los ntawm Allen Manufacturing Company nyob rau hauv Hartford, Connecticut, nyob ib ncig ntawm 1910. Lub tuam txhab tshwj xeeb hauv kev tsim cov screws, thiab cov invention ntawm lub hexagonal socket yog ib qho tseem ceeb innovation. Thaum lub npe 'Allen' tseem cuam tshuam nrog cov ntsia hlau, ntau lwm cov tuam txhab tam sim no tsim lawv. Lub sij hawm 'allen ntsia hlau' feem ntau siv generic.Types ntawm Allen ScrewsAllen screws tuaj nyob rau hauv ntau yam variations, txhua tus tsim rau cov kev siv tshwj xeeb: Socket Head Cap Screws (SHCS): Hom ntau tshaj plaws, muaj lub taub hau cylindrical nrog lub tiaj tiaj thiab lub qhov (socket) hexagonal. Lawv muaj ntau yam thiab muaj zog zoo heev. Khawm Head Cap Screws: Feature ib puag ncig, qis-profile taub hau. Lawv feem ntau siv rau hauv cov ntawv thov uas qhov kev zoo nkauj yog qhov tseem ceeb lossis qhov kev tshem tawm tsawg. Flat Head Cap Screws: Muaj lub taub hau countersunk tsim los zaum yaug nrog rau saum npoo ntawm cov khoom. Lawv muab kev huv, kev ua tiav. Teem Screws: Feem ntau headless screws nrog lub qhov (socket) hexagonal ntawm ib kawg. Lawv raug siv los tiv thaiv ib qho khoom hauv lossis tawm tsam lwm yam khoom, feem ntau tsis siv lub txiv ntoo. Hom muaj xws li khob point, cone point, dog point, thiab flat point. Lub xub pwg Screws (Stripper Bolts): Cov screws no muaj ib tug du, unthreaded xub pwg ntawm lub taub hau thiab xov. Lawv feem ntau yog siv los ua pivots lossis cov lus qhia hauv cov khoom sib dhos.Allen Screw Qhov ntau thiab tsawgAllen screws muaj nyob rau hauv ob qho tib si metric thiab imperial (inch) qhov ntau thiab tsawg. Nkag siab txog qhov sizing system yog qhov tseem ceeb rau kev xaiv cov ntsia hlau kom raug rau koj daim ntawv thov.Metric Allen Screw Qhov Loj Metric allen screws raug xaiv los ntawm 'M' ua raws li tus lej qhia lub npe kab ntawm cov ntsia hlau hauv millimeters (piv txwv li, M3, M4, M5, M6, M8, M10, M12). Qhov ntev ntawm cov ntsia hlau kuj tau teev nyob rau hauv millimeters.Imperial (Inch) Allen Screw SizesImperial allen screws raug xaiv los ntawm ib feem lossis tus lej loj (piv txwv li, 1/4-20, 5/16-18, #6-32, #8-32, #10-24). Thawj tus lej sawv cev rau qhov nominal txoj kab uas hla ntawm cov ntsia hlau, thiab tus lej thib ob qhia txog cov xov tooj ntawm ib nti (TPI).Kev xaiv qhov loj me yuav tsum tau ua tib zoo xav. Nov yog cov lus yooj yim rau kev siv: Metric Size Approx. Inch Equivalent Common Allen Wrench Loj (mm) M3 #.5 M4 # M5 # M6 1/4'-20 5 M8 5/16'-18 6 Cov khoom siv hauv Allen ScrewsCov khoom siv ntawm ib allen ntsia hlau ho cuam tshuam nws lub zog, corrosion kuj, thiab haum rau txawv ib puag ncig. Hlau alloy: Ib qho khoom siv uas muab siab zog thiab durability. Feem ntau kho nrog dub oxide rau corrosion kuj. Stainless hlau: Muab kev tiv thaiv corrosion zoo heev, ua rau nws zoo tagnrho rau kev siv sab nraum zoov thiab ib puag ncig nrog cov dej noo lossis tshuaj lom neeg. Cov qib feem ntau suav nrog 304 thiab 316 stainless hlau. tooj dag: Muaj kev tiv thaiv corrosion zoo thiab hluav taws xob conductivity. Feem ntau siv rau hauv daim ntawv thov hluav taws xob. Nylon: Ib lub teeb yuag thiab tsis-conductive khoom haum rau daim ntaub ntawv uas yuav tsum tau rwb thaiv tsev.Applications ntawm Allen ScrewsAllen screws yog siv nyob rau hauv ib tug ntau yam ntawm daim ntawv thov nyob rau hauv ntau yam industries: Tshuab: Kev ruaj ntseg qhov chaw hauv tshuab thiab khoom siv.
