sumo kune zvigadzirwa:

Brass Copper DIN7991/931/933 Bolts inosanganisira mhando mbiri: DIN7991 (CSK flat - musoro nemukati hex socket) yekugezesa - yekumisikidza, uye DIN931/933 (hex musoro ine chikamu / yakazara shinda) yemutoro - inotakura zvinongedzo. Yakagadzirwa kubva kundarira / mhangura, ivo vanopa yakasikwa corrosion kuramba, yakanakisa magetsi conductivity, uye inoyevedza yegoridhe kupera. Iyo DIN7991 countersunk musoro inovimbisa snag - yemahara nzvimbo; DIN931 ine shinda diki (yakanakira maworkpieces akakora), nepo DIN933 iine shinda dzakazara (dzakakodzera kuburikidza - maburi). Inowanikwa muhukuru kubva kuM2 kusvika kuM24, inoshandiswa zvakanyanya mufenicha (kushongedza kwekushongedza), midziyo yemagetsi (conductive joints), hardware yekugadzira (ornamental mounts), uye midziyo yakarurama (yakaderera-profile fixing), kuenzanisa aesthetics uye kushanda.

Mirayiridzo yekushandisa:

DIN7991: Isa uchishandisa inofananidzwa yemukati hex wrench, simbisa kusvika CSK musoro wanyatsozara neworkpiece (dzivisa pamusoro - kuomesa kudzivirira zvinhu warping).

DIN931/933: Shandisa yekunze hex wrench, uchitevera yakakurudzirwa torque nhungamiro (ona kuti ndarira ine simba rakaderera pane simbi, saka dzivirira simba rakawandisa).
Kuchengetedza: Geza mabhaudhi nguva dzose nemucheka wakaoma. Brass inogadzira patina nekufamba kwenguva; kana polishing ichidiwa, shandisa ndarira - chaiyo yekuchenesa. Dzivisa kuratidzwa kwenguva refu kune yakasimba acids kana alkalis kuchengetedza kupera.
