JC,
Thanks for the recommendation on Mutual Screw. I just placed an order for the Powers 304 stainless steel anchor rating wedge bolts. I have heard the Hilti bolts wedge bolts are better, but Hilti closed their local store in Fresno and does not do direct mail order. I still have enough hangers for the time being and I need painted hangers, which Fixe does still have but they are more expensive.
