Hexagonal hlau xaim
Kev faib tawm
Cov hlau xaim raws li txoj cai yog muab faib ua qauv txias, tawm ob pawg. Lub sijhawm ntawm tus xovtooj nyob rau hauv daim ntawv cog lus. Thaum twg tsis qhia, raws li qhov kev sib tw txias ntawm lub xeev.
Zoo
1. Ua qhov loj me, cov duab yuav tsum zoo ib yam nrog GB 3205-82 "txias teeb liab hexagonal hlau loj, zoo, qhov nyhav thiab qhov yuav tsum tau ua kom".
2. Txhim kho qhov yoojyim rau koj yuav tsum ua raws li cov kev txwv ntawm GB 3205-82 h11. Thaum twg yuav tsum muaj xov hlau ntxiv, nws yuav tsum tau muab sau rau hauv daim ntawv cog lus.
Daim ntawv thov
Cov khoom no yog tsim rau cov khoom sib xyaw thiab bolts, ceev thiab lwm yam hleb hlau hlau
