Mount comes with lag bolts and wall taps to mount to walls of different types/situations ...pre-drill holes into studs through Sheetrock. Be sure to use the correct size drill bit (slightly smaller than lag bolts) Or use wall taps. Do not over tighten bolts! Should be snug. Not necessary to hit studs if using wall "taps". If using wall taps, be sure to use the correct size drill bit (not too big, not too small) Lightly hammer in wall taps flush to wall surface. Hand tighten bolts through TV mount using a ratchet. In your situation you can pre-drill holes into metal studs and use wall taps into the Sheetrock.
