1. Icyuma cyo mu cyiciro cya 12.9 bivuga imbaraga zidasanzwe cyane zikoze mu bikoresho bya SCM435 byuma byuma, bifite imbaraga zingana na 1220Mpa nuburemere bwa 39-44HRC. Ikoreshwa cyane cyane mu myenda, hydraulic, kubumba inshinge, no mu mashini mu gihugu.

2. Ukurikije ikintu, gishobora kugabanywamo ubwoko butandukanye nka12.9 urwego rwo hanze rufite impande esheshatu, Icyiciro cya 12.9Imbere ya mpande esheshatu. urudodo, rugabanijwemo urudodo ruto, urudodo rwiza, metric, Abongereza, Abanyamerika, nibindi

3. Icyiciro cya 12.9 nuburyo bwo hejuru bwimigozi, hamwe nuburemere bukomeye nimbaraga zikomeye. Ubukomezi bwa Rockwell (HRC) burashobora gushika kuri 39-44, kandi imbaraga zayo zirashobora gushika 1220N / mm2. Nyamara, bitewe nuburyo butandukanye bwo gukora imashini, imashini ya hex (ibikombe bisa) hamwe nigice cya kabiri cyumutwe wa hex (ibikombe bizunguruka) bikozwe mubikoresho bimwe birashobora gusa kugera ku mbaraga ntoya yo mu cyiciro cya 10.9. Irashobora kandi kuzuza byuzuye ibisabwa byinganda zinganda nubucukuzi bwamabuye y'agaciro mugihe kidasanzwe nibigize.
