ISO 4759 txuj ci muaj xws li nram qab no, nyob rau hauv lub npe ntawm lub npe Kev tawm tsam tsis txaus siab:
ISO 4759-1 Tshooj 1: Bolts, screws, studs andnuts - Productgrades A, B andC
ISO 4759-3 Ntu 3: Ntxhua txuas rau kev kub nyhiab, ntses pa ceev ceev - Cov Productgrades A thiabC
ISO 4759-3 Ntu 2: Cov ntsaws qhov muag, ntsia hlau thiab ceev nrog xov diameters ntawm 1 mus txog 3 hli thiab cov khoom qib F, rau cov neeg ua haujlwm zoo
ISO 4759-1 qhia meej txog kev txiav txim siab tolerance rau bolts, screws, studs thiab ceev nrog ISO metric threads thiab nrog qib qib A, B thiab C thiab rau tapping screws nrog cov khoom qib A.
Lub tolerances, tsuas yog tolerances rau threads, xaiv tau los ntawm qhov system ntawm kev txwv thiab fits teev nyob rau hauv ISO 286-1 thiab ISO 286-2. Lub tolerances rau metric threads yog coj los ntawm cov kab mob siab kawm uas teev hauv ISO 965-3. Lub siab zam rau tapping ntsia hlau threads yog them hauv ISO 1 478.
Lub siab ntawm daim ntawv thiab txoj hauj lwm yog teev thiab qhia raws li ISO 1 1 01, ISO 801 5 thiab ISO 2692.
Lub tolerances teev nyob rau hauv qhov ntawm ISO 4759 siv rau cov fasteners ua ntej txheej thaum tsis teev. Saib kuj ISO 4042.
Kev tiv thaiv ntawm kev zam uas tau teev nyob rau hauv qhov no ntawm ISO 4759 tsuas yog raug tso cai hauv cov khoom qauv uas muaj cov laj thawj raug cai. Nyob rau hauv rooj plaub uas muaj qhov sib txawv ntawm cov kev cai kam rau ua rau qhov no ntawm ISO 4759 thiab cov khoom tsim, qhov khoom tsim yuav siv ua ntej.
Dimensions thiab tolerances muab nyob rau hauv qhov no ntawm ISO 4759 nyob rau hauv millimeters.
