When hanging an L bracket, I ran a test drill to see if there was a stud. I hit what I thought was the stud but it turns out to be a plastic stud. How do I anchor through the sheetrock? My screw will not pierce the plastic stud.
How old is the building you are working in? Only a very new one might have (ecostud.com/product_details.html ) plastic framing studs. More likley you have drilled into a plastic pipe. If your water is on and you haven't noticed a leak you have drilled into a drain line or a plumbing vent stack. If it was my house I would cut a small opening in sheet rock at that very same location to verify what you have drilled into and if it is in fact a pipe open the wall enough to repair the hole in the pipe.
Please let us know what you find. And if it is a stud made of plastic explain why a screw would not pierce it. Studs are after all supposed to be accepting of dry wall screws regardless of what they are made of.
Thank you all. As it turns out, it was a metal stud which explains the flex I felt when trying to secure the screw. I had cleaned out the screw hole with compressed air prior to posting my question but there was still sheetrock dust that made the stud appear white. I knew it wasn't an electrical or water line so I checked to see if there was such a thing as a plastic stud - and there is. Used for nonload bearing interior walls or possibly for rocking a concrete block basement. Thanks for your help.
