GEEHUA 20 stuks M4 holle pluggen, holle deurankers en schroeven, stelmoeren bloemblaadjesmoeren expansiemoeren voor aluminium bekleding, ijzeren plaat, holle kunststof panelen, dunne muren (M4)

My RV control panel was loosing the mounting screws as they were wood screws put in with no backing in 5/16 “ paneling.Saw these hollow door screws and decided to give them a try.Worked out great! Had to be careful not to make the initial hole too large as to want to limit theAnchor movement. Please notice that the hold points for the anchor are on the face of the anchor and whatever you are trying to attach needs to be pressed tight to the wall/door when tightening the screw to compress the anchor.You then can remove the screw for access as many times as necessary. Enjoy!
