Can these be used for masonite wood textured 4'X8' paneling type wall board?

Hello. The hardware pictured is for drywall installations; however, the anchor could be cut off (making it in essence a 4 gauge “pole clip”) and the resulting clip could be installed at stud locations utilizing a #8 x 1 ¼” screw. SO, as long as there are studs behind the paneling that the anchors will be installed into, yes, you can use the wall clips for paneling. Thank you for your inquiry.
