Dab tsi yog qhov txawv ntawm metric threaded pas nrig thiab British thiab American xov pas nrig?

Metric thread rodthiabBritish American threaded pas nrigyog ob txoj kev sib txawv ntawm cov xov hlau. Qhov sib txawv ntawm lawv yog feem ntau yog xav txog qhov loj ntawm tus qauv, tus naj npawb ntawm threads, bevel lub kaum sab xis thiab qhov kev siv. Hauv kev tsim khoom siv tshuab, nws yog ib qho tsim nyog los xaiv cov qauv xov tsim nyog raws li qhov xwm txheej tshwj xeeb ..

1. Dab tsi yog qhov sib txawv loj tshaj ntawm metric stud bolt thiab British thiab American stud bolt?

Metric stud ntsia liaj qhov roojtau nrov nyob rau hauv Fabkis, thiab nws cov yam ntxwv yog hais tias nws siv millimeters li units, muaj tsawg threads, thiab muaj ib tug bevel kaum sab xis ntawm 60 degrees. CovBritish thiab American stud boltoriginated nyob rau hauv lub tebchaws United Kingdom thiab lub tebchaws United States, thiab nws cov yam ntxwv yog hais tias nws siv ntiv tes ua units, muaj ntau threads, thiab muaj ib tug bevel kaum sab xis ntawm 55 degrees.

2. Qhov txawv ntawm metric threaded rod din975 thiab British thiab American threaded pas nrig din975 xov qhov ntau thiab tsawg?

Hais txog qhov loj me, qhov loj ntawm metric threads rod din975 yog qhia nyob rau hauv cov nqe lus ntawm txoj kab uas hla (mm) thiab pitch (mm), thaum British thiab American threads pas nrig din975 yog qhia nyob rau hauv cov nqe lus ntawm qhov loj (inch), suab, thiab xov program ( tus naj npawb ntawm threads).

Piv txwv li, M8 x 1.25 xov, qhov "M8" sawv cev rau txoj kab uas hla ntawm 8 hli, thiab "1.25" sawv cev qhov deb ntawm 1.25 hli ntawm txhua txoj xov. Hauv British thiab American threads, 1/4 -20 UNC sawv cev rau cov xov loj ntawm 1/4 nti, ib lub suab ntawm 20 threads ib nti, thiab UNC sawv cev rau lub teb chaws coarse-grain txheem rau cov xov.
