Raws li peb mus txog xyoo 2026, tus nqi rau cov khoom no tau nce zuj zus los ntawm cov khoom siv raw tsis hloov pauv, txheej txheej txheej txheem thev naus laus zis, thiab cov khoom lag luam ncaj qha cov saw hlau ua tau zoo. Phau ntawv qhia no muab cov lus qhia dav dav, kev lag luam tus nqi tam sim no, thiab cov txheej txheem xaiv cov kws tshaj lij rau engineers thiab cov kws tshaj lij kev muag khoom nrhiav kev txhim khu kev qha, raug nqi ncaj qha los ntawm cov tuam ntxhab.

Dab tsi yog Round Head Hex Socket Head Cap Screws?

A round taub hau hex socket taub hau hau ntsia hlau, feem ntau hu ua lub pob taub hau lub qhov (socket) ntsia hlau, yog ib hom ntawm lub tshuab ntsia hlau tshwj xeeb los ntawm nws qhov sib npaug, dome-puab sab saum toj thiab lub cylindrical bearing nto hauv qab. Tsis zoo li lub taub hau lub taub hau lossis lub taub hau lub taub hau, lub taub hau puag ncig tsim muaj qhov du, zoo nkauj tiav thaum tuav cov profile qis dua tus qauv hex cap screws.

Lub ntsiab feature yog lub sab hauv hexagonal socket (Allen tsav), uas tso cai rau siab torque daim ntawv thov yam tsis muaj slipping, ua rau lawv zoo tagnrho rau cov rooj sib txoos qhov chaw txwv los yog qhov twg ib tug protruding sab nraud lub taub hau yog undesirable. Cov fasteners no nruj me ntsis ua raws li cov qauv thoob ntiaj teb, tshwj xeeb tshaj yog TS EN ISO 7380, uas tswj lawv qhov ntev, mechanical zog, thiab tolerances.

Hauv cov ntawv thov kev lag luam, lawv zoo dua rau kev ruaj ntseg npog, tiv thaiv, thiab tshuab qhov chaw uas qhov zoo nkauj thiab tiv thaiv kev co yog qhov tseem ceeb. Lub tshuab tsav sab hauv txo qhov kev pheej hmoo ntawm cam-tawm piv rau Phillips drives, kom ntseeg tau tias muaj zog clamping zoo sib xws thaum sib dhos.

ISO 7380 Specifications thiab Technical Standards

Nkag siab qhov tseeb qhov ntev tau teev tseg hauv TS EN ISO 7380 yog qhov tseem ceeb rau engineering compatibility. Cov qauv no qhia txog geometry rau metric series round head socket screws. Kev sib txawv ntawm cov specs no tuaj yeem ua rau kev ua tsis tiav los yog cov cuab yeej puas.

Tus qauv npog ntau qhov ntau thiab tsawg, feem ntau yog los ntawm M3 txog M24, txawm tias muaj nyob ntawm cov chaw tsim khoom. Cov ntsiab lus tseem ceeb muaj xws li lub taub hau txoj kab uas hla, lub taub hau qhov siab, thiab qhov tshwj xeeb loj ntawm qhov tseem ceeb hauv hexagon xav tau.

Ntsiab Dimensional Parameters

Lub taub hau txoj kab uas hla ntawm ISO 7380 ntsia hlau feem ntau yog kwv yees li 1.5 npaug ntawm nominal xov txoj kab uas hla. Qhov dav dav ntawm cov kabmob no pab faib cov khoom sib npaug thoob plaws qhov chaw mating, txo qhov kev pheej hmoo ntawm indentation lossis deformation hauv cov ntaub ntawv softer xws li txhuas lossis yas.

Lub taub hau qhov siab yog qhov qis, feem ntau nyob ib ncig ntawm 0.6 npaug ntawm nominal txoj kab uas hla. Qhov profile qis no yog thawj qhov laj thawj engineers xaiv lub fastener no rau lwm tus thaum ntsug clearance raug txwv. Kev hloov ntawm lub shank mus rau lub taub hau yog du, txo qis kev ntxhov siab.

Cov chav kawm kam rau ua thiab haum

TS EN ISO 7380 Kev tswj hwm nruj rau cov chav kawm rau cov xov thiab lub taub hau qhov ntev. Feem ntau cov khoom lag luam zoo tshaj plaws-cov ntsia hlau ncaj qha ua raws li kev ua siab ntev hauv chav kawm 6g rau cov xov sab nraud, ua kom muaj kev haum zoo nrog cov qauv ceev thiab cov qhov tapping.

Lub qhov (socket) qhov ntev yog qhov tseem ceeb sib npaug. Yog tias lub hexagon me dhau lawm, tus yuam sij Allen yuav tsis haum; yog tias loj heev, torque kis tsis tau, ua rau stripped sockets. Reputable manufacturers siv precision txias taub hau thiab machining los tswj cov nruj tolerances tsis tu ncua.

Cov lus nthuav dav dav rau ISO 7380 Screws
