fischerDuoPower 3/16" x 1", 100 Plugs Without Screws, Powerful Universal Plug with Intelligent 2-Component Technology for Fastenings in Concrete, Bricks, Drywall, Chipboard, etc

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."

I’ve bought these fischer DuoPower anchors multiple times, and they never disappoint. The highest quality possible, holding strong in various materials. I always go with this brand—highly recommended!

There are many types of wall anchors. Some like "Molly bolts" and "Toggle bolts" are quite secure in hollow walls, but useless in solid walls. Some like "Tapcon", "RedHead, and "Strike Anchors" only work in solid walls. These DuoPower plug anchors are light weight anchors that will function in both solid or hollow walls. The manufacturer says they adapt to almost any material, or material thickness. They are a great improvement over plastic anchors. I have occasionally had various problems over the years with nearly all anchor types. The Fischer DouPower anchors have so far, been very well behaved. Consult the instructions for the best results. You will also need the correct size drill bit, designed for the material you are installing the anchors into.

I used these to anchor porch rails to concrete and they really provide a strong hold. The screws are quite long (2 5/8 inches), and extend about 13/16 or 7/8 of an inch beyond the end of the anchor. The anchor and screws worked well in 6 inch concrete, but might be too long in some applications. The anchor will work with # 8, #10, and #12 screws as indicated on the anchor. The screws should be at least 1 3/4 inches in length. These anchors are way better than the typical plastic anchor. I rate the anchors 5 stars, but the box was broken up and the anchors and screws were inside the shipping bag. Luckily, I was able to salvage the box with some packaging tape which prevented from storing the anchors and screws in a Ziploc bag.

Works better than most similar items. Just be careful to not over tighten.

The product arrived in a day. It was in a padded envelope, the box of anchors inside was wrecked. I had to tape it back together. I tried the product on a side wall I made up for a hot air solar panel. I glued 5.2mn overlayment to polycanurate foam. I then drilled 1" deep holes 3/16 in diameter every 4" inches into the panel. Into the holes inserted the anchors. They hold awesomely. I am now able to screw down the flashing into a wall made of insulating foam. The anchors will take a #8 screws. Awesome product GR8 value less than 13 cents an anchor👍👍

This is a fantastic product. They work extremely well and versatile in a range of wall materials. If you see any reviews about them "falling out of the wall" that person clearly hasn't followed instructions on how to use them.I unfortunately am giving the product 3 stars since the Amazon fulfillment center can't figure out how to send me the right product. I've ordered boxes of (100) 1/4" duo-power anchors multiple times now and they keep sending me 50 anchors with 50 screws.Fischer, you might want to look into this. They keep F-ing up your orders.The boxes of 100 anchors and boxes of 50 pairs seem to have the same UPC code, unless one of them is incorrectly boxed. It's happened four times now.I love your products. If I could only get my hands on the right ones.

Best plugs for drywall or stone .
