ST12 Xaraashka birta ah ee Qabow

Birta duuban ee qabowgu waa alaabtayada ugu caansan uguna badan ee la isticmaalo. Astaanteeda guud ahaan waxaa loo qaybin karaa: ST12, ST13, ST14, ST15, ST16 iyo wixii la mid ah.


ST12 waa heerka Jarmalka (DIN1623), Waa bir qabow oo caadi ah. Mabda 'ahaan, ST12 kaliya waa la foorarsan karaa oo la samayn karaa, lamana oggola wax shaabad ah.
