Neeg Asmeskasboltsyog ib qho kev sib txuas uas feem ntau siv hauv kev siv tshuab engineering, kev tsim kho engineering, thiab lwm yam kev siv hauv kev lag luam. Cov lus qhia me me yog tus qauv tseem ceeb rau Asmeskas cov bolts, siv los qhia cov kev txwv xws li txoj kab uas hla, qhov ntev, thiab cov xov tooj rau kev xaiv kom raug thiab siv hauv kev tsim, tsim, thiab kev saib xyuas.
Qhov loj specification rooj rau AmericanboltsFeem ntau siv ob tus qauv: Unified Coarse thiab Fine Thread (UNC) thiab Unified Fine Thread (UNF). UNC threads yog siv nyob rau hauv feem ntau daim ntaub ntawv nyob rau hauv general mechanical thiab kev tsim kho engineering, nrog tsawg threads ib nti, ua rau lawv ntau haum rau high-lub zog thiab hnyav-duty daim ntaub ntawv; UNF threads yog siv nyob rau hauv cov xwm txheej uas yuav tsum tau nruj kev sib txuas thiab finer kho, nrog ib tug ntau dua ntawm threads ib nti, ua rau lawv zoo dua rau kev siv nyob rau hauv precision machinery thiab cov khoom siv hluav taws xob.
Cov hauv qab no yog cov lus qhia me me (UNC thiab UNF) rau Asmeskasbolts:
UNC xov:
-1/4-20: Hais txog ib txoj kab uas hla ntawm 1/4 nti nrog 20 threads ib nti.
-5/16-18: Hais txog ib txoj kab uas hla ntawm 5/16 ntiv tes nrog 18 threads ib nti.
-3/8-16: Hais txog ib txoj kab uas hla ntawm 3/8 ntiv tes nrog 16 xov ib nti.
-1/2-13: Hais txog ib txoj kab uas hla ntawm 1/2 nti nrog 13 threads ib nti.
-5/8-11: Hais txog ib txoj kab uas hla ntawm 5/8 ntiv tes nrog 11 threads ib nti.
-3/4-10 yog hais txog txoj kab uas hla ntawm 3/4 ntiv tes nrog 10 xov ib nti.
-1-8: Hais txog ib txoj kab uas hla ntawm 1 nti nrog 8 threads ib nti.
UNF xov:
-1/4-28: Hais txog ib txoj kab uas hla ntawm 1/4 nti nrog 28 threads ib nti.
-5/16-24: Hais txog ib txoj kab uas hla ntawm 5/16 ntiv tes nrog 24 threads ib nti.
-3/8-24: Hais txog ib txoj kab uas hla ntawm 3/8 ntiv tes nrog 24 threads ib nti.
-1/2-20: Hais txog ib txoj kab uas hla ntawm 1/2 nti nrog 20 xov ib nti.
-5/8-18: Hais txog ib txoj kab uas hla ntawm 5/8 ntiv tes nrog 18 threads ib nti.
-3/4-16: Hais txog ib txoj kab uas hla ntawm 3/4 ntiv tes nrog 16 threads ib nti.
-1-14: Hais txog ib txoj kab uas hla ntawm 1 nti nrog 14 threads ib nti.
Cov lus qhia me me saum toj no tsis ua tiav, thiab lwm yam kev qhia me me tuaj yeem siv rau hauv kev siv tswv yim. Tsis tas li ntawd, lub koom haum American National Standards Institute (ANSI) kuj tseem qhia txog lwm hom xov xwm Asmeskas, xws li American coarse pitch thread (NC) thiab American fine pitch thread (NF), txhua tus nrog rau lawv qhov kev thov thiab qhov zoo uas yuav tsum tau ua. xaiv raws li cov ntawv thov tshwj xeeb.
Zuag qhia tag nrho, kev xaiv kom raug thiab siv American style bolts yuav tsum xav txog ntau yam, nrog rau kev ntxhov siab, kev thauj khoom, corrosion, kub, thiab ib puag ncig yam. Xaiv qhov tsim nyog qhov tshwj xeeb, cov khoom siv, thiab txheej txheej yog qhov tseem ceeb, thiab kev txhim kho kom zoo, nruj, thiab tshuaj xyuas raws li cov qauv tsim nyog los xyuas kom meej qhov kev nyab xeeb thiab kev ntseeg siab ntawm kev sib txuas bolted.
