fischer DuoPower 1/4" x 1-3/16", Powerful Universal Plug with Intelligent 2-Component Technology for fastenings in Concrete, Bricks, Gypsum plasterboard, chipboard, etc., 100 Plugs Without Screws

The DuoPower has rapidly become my go-to solution for all sorts of anchoring needs. What sets this product apart is its intelligent function: it's the first plug I've seen that adapts to the material it's being used on. Whether it's solid, perforated, or panel building materials, the DuoPower smartly adjusts to transfer high loads through folding, expanding, and knotting.In my experience, this plug is truly an all-in-one solution for a wide variety of building materials. The ingenuity of the 2-component plug lies in the grey component that automatically activates the optimal operating principle based on the material, while the red component's expansion wings ensure safe spreading.What impressed me further was its strength. Despite being compact and short, the DuoPower requires noticeably less drilling effort and shorter screws. It's thoughtfully designed to prevent slipping into the borehole, resist rotation within the drillhole, and offer tactile feedback when perfectly installed.The DuoPower anchors have proven to be incredibly versatile, working well for attaching everything from shower curtain rails to mailboxes, lamps, motion sensors, and signs in a variety of materials such as concrete, bricks, natural stone, gypsum plasterboard, fibreboard, and chipboard.From my perspective, these are the best drywall and multipurpose anchors on the market. They provide an excellent grip and are incredibly straightforward to install. I couldn't recommend them more."

Now I only need to carry around this one wall plug in order to mount screws into a variety of wall types, replacing several others. And it has better grip than most!

Notable occurrence: since installing these, we had a 3.5 magnitude earthquake (epicenter ~1 mile from my house) and 2.5 aftershock. The guitar collection is still hanging up just fine.I recently purchased a wall-mount guitar hanging system. The rail-based system with movable guitar hangers was just what I needed to get a good chunk of my collection off the floor and nicely displayed. BUT the included wall hangers were utterly sub-par. Half of them were barely gripping the screw and even once a screw was fully inserted, they could be pulled right out of the drywall--hardly what I want with 16 guitars. And because the system is a long wall-mounted rail with evenly spaced holes, I didn't have the option of ensuring that I could hit multiple studs. and needed the drywall anchors to be pitching in.After looking through quite a few products I stumbled upon these. Rather than giving up on the system entirely, I simply tossed all of the anchors that came with it and replaced with these. It's now easily holding 16 guitars and feels like it would be able to hold twice as many (although I'm not going to try).No, this isn't the most exciting product out there. But if you're going to hang something up and rely on drywall anchors, it makes sense to use ones that will work. These do the job perfectly, and are notably better than the anchors they were replacing, so I have to give them 5-stars.

These work great in concrete, holds well, note these do not come with screws!

I have been purchase wall mounts from Home Depot for the cost of a used car. I happen upon these wall plugs on Amazon for a fraction of the price for a few at Home Depot. I never used the screws that come with packages I have purchased from there. Even with my military discount, Amazon was better buy. These wall plugs are sturdy and work GREAT with plaster walls. I have install floating shelves in my kitchen with this brand plugs and heavy duty deck screws and bolts. The shelves have been floating for about a year, now. The plugs are the best on the market. Just drill the right size hole for the plug.
