I need advice on hanging my 70 lb. tv on a solid concrete wall. I have a few questions: 1. The mount for the TV has two holes and they are only 1 cm wide -- only wide enough for a "medium duty" lag bolt/lead anchor, will this hold my TV? 2. I'm renting and am conscious of not messing up the walls too much, so if I countersink the anchor so that when I leave I can cover it up, will it negatively effect the amount of weight it will hold? 3. Can I use a masonry bit? I've read that a hammer drill is preferred, but I would really rather not have to rent one. 4. I've read lots about tapcon screws on this forum but can't find any info on how much they hold. Are they a good option for me (especially in light of the fact that I can only use 2)? Thanks in advance for your help.

Good morning! I am trying to find a supplier of those plastic, nylon or composite feet for those folding camp or bag chairs. Mostly made in China or wherever. I know they're cheap (but so am I) and the fabric and metal is good and not worth throwing out the whole chair. These are sold by Walmart, BJ's, Sam's Club and Costco so there are different styles. Don't want to glue the old feet or repair for obvious reasons. Any ideas would be appreciated. Thanks all.
