I recently bought a 40-in. flat screen TV, only to find I have metal studs spaced 24-inches apart in my wall. The TV itself only weighs about 29 lbs. (the wall mount about 3-4 lbs.), but am unsure whether it is a smart idea to bolt the mount into the metal studs. It's an interior wall and the studs look lightweight, but I'm thinking of using two toggle bolts in each stud which should do the trick. Is this a bad idea?
