Kukho iintlobo ezi-4 ze-hex nuts ezisetyenziswa rhoqo:
1. GB/T 41-2016 “Type 1 Hex Nut Grade C”
2. GB/T 6170-2015 “Type 1 Hex Nut”
3. GB/T 6175-2016 “Type 2 Hex Nuts”
4. GB/T 6172.1-2016 “Hexagon Thin Nut”
Umahluko ophambili phakathi kwamantongomane amane asetyenziswa ngokuqhelekileyo ngoluhlobo lulandelayo:
1. Ubude bamandongomane bohlukile:
Ngokwamalungiselelo omgangatho wesizwe we-GB/T 3098.2-2015 "IiPropati zeMechanical of Fasteners Nuts", kukho iintlobo ezintathu zokuphakama kwamantongomane:
——Udidi lwesi-2, i-nut ephezulu: ubude obuncinane mmin≈0.9D okanye >0.9D;
——Udidi 1, indongomane eqhelekileyo: ubude obuncinane mmin≈0.8D;
——Udidi lwe-0, i-nut ebhityileyo: ubude obuncinane 0.45D≤mmin<0.8D.
Qaphela: D yi-diameter yegama lomsonto we-nut.
Phakathi kwamane angasentla asetyenziswa rhoqo:
I-GB/T 41-2016 “Uhlobo 1 lwe-Hex Nut iBanga C” kunye ne-GB/T 6170-2015 “Uhlobo lwe-1 Hex Nut” ludidi lwe-1 yamantongomane aqhelekileyo, kwaye ubude obuncinane be-nut mmin≈0.8D.
I-GB / T 6175-2016 "Uhlobo lwe-2 ye-Hex Nuts" luhlobo lwe-2 i-nut ephezulu, kunye nobude obuncinane be-nut mmin≥0.9D.
I-GB/T 6172.1-2016 "I-Hexagon Thin Nut" luhlobo lwe-0 nut nut, kwaye ubude obuncinane be-nut yi-0.45D≤mmin＜0.8D.
2. Amanqanaba emveliso ahlukeneyo:
Amanqanaba emveliso amandongomane ahlulwe abe ngamabakala A, B kunye noC.Amabakala emveliso anqunywe ngubukhulu bokunyamezela.Ibakala lelona lichanekileyo kwaye ibakala C lelona lichanekileyo.

Uluhlu lwedayamitha yegama elihambelana nodidi lwe-nut kunye nebakala lokusebenza liboniswe kwitheyibhile engezantsi.
Amantongomane asemgangathweni (uhlobo lwe-1) kunye namantongomane aphezulu (uhlobo lwe-2) olwenziwe nge-carbon steel kunye nentsimbi ye-alloy kufuneka isetyenziswe kunye ne-fasteners yangaphandle ye-threaded kwitheyibhile elandelayo, kunye namantongomane anamanqanaba aphezulu okusebenza kwamandla angatshintsha amantongomane ngamabakala aphantsi okusebenza.
Amantongomane asemgangathweni (uhlobo 1) ngawona asetyenziswa kakhulu.
Amantongomane amade (uhlobo lwe-2) asetyenziswa ngokubanzi kwiidibaniso ezifuna ukuchithwa rhoqo.
Amandongomane abhityileyo (Uhlobo 0) anomthwalo ophantsi wokuthwala umthwalo kunamandongomane asemgangathweni okanye amade, ngoko ke akufunekanga ukuba alungiselelwe usetyenziso oluchasene nokukhubeka.
Amantongomane amancinci (uhlobo lwe-0) asetyenziswa ngokubanzi kwizakhiwo ezichasene ne-double nut.
