10 Pieces Hollow Metal Cavity Fixing Hollow Door Anchor for 0-5mm Door Extra Short Hollow Wall Anchors Aluminium cladding Sheet Steel Pipe, Iron Sheet, Hollow Plastic Sheet (8 * 16MM)

Screws had pulled out of the lower hinge on our metal storm door (a typical screen door but that we just keep the glass in instead of a screen). Used these and, a month in so far, they continue to work like a charm. Note, I didn't buy the setting tool they recommend for holding onto the anchor b/c I wasn't sure it would fit in the tight workspace area, so we used a grip plier instead. However, it took two people: one to use the grip plier to keep the anchor from turning, and the other to screw it in. It took a bit of tries to hold onto the anchors firmly with the plier, but it ultimately worked.

Have hard plastic cover on my truck - its hinge system was pop rivetted onto the cover -- Yeah that didn't work for me...So when I decided to make it better - I sanded cover smooth - dialed in the lines of the cover to be laser straight and removed the pop rivets. Tried RivNuts but they didn't get a good solid bite on the mounting area. So I found these. They locked in to tight it trued up the way the thing shuts enough that I also went to Actuator rods rather than pneumatic ones - Paint is going on now - Black Ice Pearl to match rest of truck....Love This!!!!

If you need more than one of these, you MUST get the setting tool.Without it it's really difficult to compress them. They will spin.With the tool they work quite nicely. And the tool can also be used for other molly bolts.

Good quality and easy to use

I was looking for something that would hold in the thin metal of a screen door that has the weight of storm windows also. Screws would not hold in the metal alone.I've been complimented on how smoothly my door swings now that the hinges are firmly attached.

So...I drill a hole for it. I insert the anchor. It was a bit touch to get it over the little hump in the middle. I figured that the drill diameter was perfect But once I tried to set it by turning the screw, the flange would spin freely. Could not turn the screw.

I did use them for something they weren’t really designed to be used for…So for that application they worked well, but were difficult to install. They do not have any sort of grasp to hold the piece in place without spinning while you try to get the insert to expand. I needed to hold the insert with a plier while trying to tighten the screw. Not easy to do. This company should add some small pins to the insert to hold it in place and market them for hollow core door rack instillations.

I have been forever looking for a good way to permanently secure hooks to these modern hollow core interior doors. These things work perfectly.I just drilled a 5/16 hole, set the anchor, and held it by the outside rim with a small pair of pliers while I used a screwdriver to tighten it up. One fully secured, it is a solid as a rock.I ordered another set just to have in my hardware inventory.Perfect!
