Torquing a bolt with a paper or cork gasket under a sheet metal cover isn't a good idea. Tighten the bolt until there's no clearance between the cover and the gasket, and then tighten another 1/6 turn of the bolt head (1 flat of the 6-point bolt). Overtightening can flatten or tear the gasket material near the bolt holes.
