Can anyone advise on how to hang crate and barrel gun metal frames on drywall? i bought 9 pieces. the heaviest is 9.75 lbs. lightes is probably half that. They have the anchors shown in the photo below them. instructions say ”nail into wall”. will nails suffice and if so, what kind? or so I need hangman double headed bear claw hangers? I would rather not put screws into the wall if nails will do but need some expert guidance on whether nails will suffice. Thank you!
