I am wondering if the following exists. I need a fastener that can fit (gently hammered) into a drilled whole in drywall (like an anchor), can be secured to the drywall with sharp points (I envision these "points" circling the top of the fastener and bending back over the fastener so that they grip the drywall when it is gently hammered into the hole), and then the fastener itself will except a threaded bolt.
I am hanging a railing and one of the points where the railing will be secured is restricted by the fact that there is a pocket door behind the drywall. I have a bolt that has been sheared so that it will not interfere with the pocket door, but I need to be able to fasten it so that it is relatively strong and secure.
Does this type of fastener exist?
I am trying to use a matching bolt, so that is why I have not utilized an anchor. I can't seem to find one large enough to fit the diameter of the bolt.
