I have a heavy piece of metal artwork mounted at the head of the bed in my camper van. It has very few possible attachment points. All I had on hand was the basic plastic type of these fasteners. They work fine holding cables to the floor, etc. in places where they don't get much contact. But I tend to smack the artwork around while changing my pillows and getting stuff from under the bed area, etc. These metal fasteners have got it SOLID on the wall now. No more rattle and annoyance. Nice improvement. Would recommend.
