Mtedza wa 2H ndizitsulo zapamwamba kwambiri, zolemetsa zomwe zimagwiritsidwa ntchito kwambiri pamakina ndi mafakitale.Wopangidwa kuchokera ku chitsulo cha carbon steel, mtedzawu wapangidwa kuti uzitha kupirira katundu wambiri komanso umapereka ntchito zokhazikika ngakhale m'malo ovuta kwambiri.
Ndi gulu lake lapadera la 2H lolimba lamphamvu, mtedzawu umapereka mphamvu zosayerekezeka komanso zolimba zomwe zimapitilira ma DIN wamba ndi ma ISO.Izi zimapangitsa kukhala chisankho choyenera kwa ntchito zolemetsa zomwe chitetezo ndi kudalirika ndizofunikira, monga pomanga, migodi, ndi mafakitale amafuta ndi gasi.
Nati ya 2H imakhala ndi mawonekedwe a hexagonal omwe amapangitsa kuti ikhale yosavuta kukhazikitsa pogwiritsa ntchito wrench kapena socket.Kugwirizana kwake ndi ma bolts okhazikika ndi zomangira kumapangitsanso kukhala yankho losunthika pamagwiritsidwe osiyanasiyana.
Kuphatikiza pa mphamvu zake zapadera komanso kulimba, mtedza wa 2H umalimbananso ndi dzimbiri komanso dzimbiri.Izi zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito m'malo ovuta kumene kukhudzana ndi chinyezi ndi mankhwala ndizofala.
Wopangidwa ndi miyezo yapamwamba kwambiri, mtedza wa 2H umayesedwa mozama ndikuwunika kuti uwonetsetse kuti ukukwaniritsa kapena kupitilira zomwe makampani amafunikira.Ndi ntchito yake yodalirika, moyo wautali wautumiki, komanso kuyika kosavuta, mtedza wa 2H ndi gawo lofunikira pa ntchito iliyonse yolemetsa yamakampani.
Kaya mukufunika kumangirira zida zolemera, makina, kapena zida, mtedza wa 2H ndiye yankho labwino lomwe limapereka mphamvu zosayerekezeka, kulimba, komanso chitetezo.
