Lower Control Arm Bolt
Hi all changed out my drivers side lower control arm it was all going smooth until I tried to put main bolt back in. I have a really sore right wrist so I was using my electric impact gun. Before u know it the bolt got stripped,I tried to rethread it and that didnt seem to work. I did notice that on the end of bolt its stamped 10...was wondering if that's a hardness stamp. I went to dealer and they could only order me the bolt as I also need the nut. So I went to a local automotive place and bought a shoulder bolt 12mmX1.80mm and bolted it back up. Just wondering if that bolt is a special hardened bolt,it was easily re threading didnt seem hard at all and I noticed that it looked a bit bent too....Thanks

Well I sloved my own dilemma long ago just ahvent had time to post. The bolt I replaced turned out to be a hardened bolt grade 8.8 which in fact is a grade 8. My friend confirmed that the 10 on bolt head original just means mazdas metric grade which is no higher than a grade 8....By the way car runs smooth as can be ...
