E-Z Ancor Twist-N-Lock 50 Drywall Anchors with Screws (25-Pack) are great for hanging light fixtures, mirrors, clocks and picture frames in drywall. Install with only a #2 Phillips screwdriver and #6 x 1-1/4 in. screws (included). No pre-drilling required - screw directly into drywall. E-Z Ancor Twist-N-Lock 50 Drywall Anchors support 50 lbs. when installed in 1/2 in. drywall.
5 out of 17 broke when inserting them into the wall. I love this type of anchor, but this particular brand/type's plastic is too rigid and it easily breaks when (even gently)pounding into the wall. I like the ones with the sharp, knife-like tip better, because you can almost push them in. These are hard to get in. Once they're in, they're fine, but other brands seem much better. These can be frustrating. I thought I hit a stud at times, but no, it was just the anchor cracking.
