Waa maxay nooca birta iyo birta ku habboon fasalka dhabta ah ee 12.9 hex socket screws

Fasalka 12.9 boolal iyo boolal Tixraac boolal xoog aad u sarreeya oo laga sameeyay 35CrMo, 42CrMo, iyo B7 alaabo bir ah, oo leh ugu yaraan xoogga xajinta ee 1220Mpa iyo adkaanta 39-44HRC. Waxaa inta badan loo isticmaalaa dhar-dharka, hydraulic, qaabeynta duritaanka, iyo warshadaha mashiinada gudaha.

1. 12.9 sharoobada screw waxaa loola jeedaa caag ultra-sare leh oo ka samaysan SCM435 aluminium bir ah, oo leh ugu yaraan xoog adkaysi ah 1220Mpa iyo adkaanta 39-44HRC. Waxaa inta badan loo isticmaalaa dhar-dharka, hydraulic, qaabeynta duritaanka, iyo warshadaha mashiinada gudaha.

2. Marka loo eego shayga, waxa loo qaybin karaa noocyo kala duwan sida12.9 darajo laba geesood oo dibadda ah, 12.9 darajoboolal madax lix geesood ah(koob madaxa), 10.9 madaxa countersunk madaxa boolal laba geesood ah (koob fidsan), 10.9 darajo semi wareeg ah gudaha afar geesle ah (koob wareeg ah), 12.9 fasalka dhigay boolal (mitirka mashiinka), 12.9 fasalka 12.9 boolal gudaha afar geesood ah, iwm. dunta, waxay u qaybsantaa dun aan dhab ahayn, dun fiican, metric, British, American, iwm.

3. Fasalka 12.9 waa noocyada ugu sarreeya ee boolal, oo leh qallafsanaan sare iyo xoog xajin. Adaggeeda Rockwell (HRC) waxay gaari kartaa 39-44, xooggeeda xajinta waxay gaari kartaa 1220N/mm2. Si kastaba ha ahaatee, iyadoo ay ugu wacan tahay qaababka kala duwan ee wax-soo-saarka sharoobada, boolal hex countersunk (koobab fidsan) iyo boolal madax wareeg ah oo badh ah (koobab wareeg ah) oo laga soo saaray isla shay ayaa kaliya lagu gaari karaa xoogga ugu yar ee darajada 10.9. Waxa kale oo ay si buuxda u buuxin kartaa shuruudaha sare ee shirkadaha warshadaha iyo macdanta ee xirmooyinka xilliyada iyo qaybaha gaarka ah.
