Tilmaamaha Halbeegga ah ee Iskiriinta

Heerarka inta badan la isticmaalo waa kuwan soo socda:
GB-China Heerarka Qaranka (Heerka Qaranka)
ANSI-Maraykanka Heerarka Qaranka (Heerka Ameerika)
DIN-German Heerarka Qaranka (Heerka Jarmalka)
ASME-American Society of Mechanical Engineers Standard
JIS-Japanese Heerarka (Heerka Jaban)
BSW-British Heerka Qaranka

Marka lagu daro qaar ka mid ah cabbirka aasaasiga ah, sida dhumucda madaxa iyo madaxa ka soo horjeeda, qaybta ugu kala duwan ee heerarka la soo sheegay ee boolalku waa dunta. Xargaha GB, DIN, JIS, iwm waxay ku wada jiraan MM , oo si wada jir ah loogu yeero metric threads.Xargaha sida ANSI, ASME, waxay ku jiraan inji waxaana loo yaqaan dunta caadiga ah ee Maraykanka.Marka laga reebo metric threads iyo threads American, waxa kale oo jira halbeeg BSW-British ah, iyo duntu sidoo kale waxay ku jiraan inji, oo caadi ahaan loo yaqaan threads Whitworth.

Dufanka mitirka ahi waxa uu ku jiraa MM (mm), xagalkeeduna waa 60 darajo.Xadhkaha Ameerika iyo Imperial labadaba waxaa lagu cabbiraa inji.Xagalka dunta Maraykanku waa 60 darajo, halka xagasha dunta Ingiriisku ay tahay 55 darajo.Sababtoo ah cutubyada kala duwan ee cabbirka, hababka matalaadda ee dunta kala duwan ayaa sidoo kale kala duwan.Tusaale ahaan, M16-2X60 waxay u taagan tahay dun mitir ah.Waxay si gaar ah uga dhigan tahay in dhexroorka magaciisu yahay 16MM, garoonkuna waa 2MM, dhererkuna waa 60MM.Tusaale kale: 1/4-20X3/4 macnaheedu waa dunta nidaamka Ingiriiska.Macnaheeda gaarka ah waa dhexroorka magaca furuhu waa 1/4 inch (hal inch=25.4MM), waxaa jira 20 ilkood oo hal inch ah, dhererkuna waa 3/4 inch.Intaa waxaa dheer, haddii aad rabto inaad muujiso boolal-maraykanku sameeyay, UNC iyo UNF ayaa badanaa lagu daraa ka dib markii birta Ingiriisi samaysay si loo kala saaro dunta qallafsan ee Maraykanku sameeyey iyo dunta fiican ee Maraykanku sameeyey.

Yihe Enterprise waa shirkad ku takhasustay soo saarista boolal amchine-ka ANSI, mashiinka BS, jiingadaha bolt, indlcuidng 2BA, 3BA, 4BA;Mashiinnada Jarmal-sameeyay DIN (DIN84 / DIN963 / DIN7985 / DIN966 / DIN964 / DIN967);Taxanaha GB iyo noocyada kale ee alaabta caadiga ah iyo kuwa aan caadiga ahayn sida mashiinnada mashiinnada iyo dhammaan noocyada kala duwan ee mashiinnada naxaasta ah.
