fischer DuoPower 1/4" x 1-3/16" S PH, 50 Plugs & 50 Screws, Powerful Universal Plug with Intelligent 2-Component Technology for Fastenings in Concrete, Bricks, Drywall, Chipboard, etc

Used these for security camera junction boxes. Work great.

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👍👍

Good anchors.

This fastener could be called universal. If inserted into a wall deeper than the anchor, it will expand and tighten to give maximum strength. If it is inserted into a wall shallower than the anchor, the back end will flare out, toggle-bolt like. (and without the tiresome pull and tighten of a toggle bolt) I gave its durability 4 stars, hoping that holds. Haven't had it in place long enough to know. One installation note: gently tap the anchor into place until its flush with the wall. Any loss of its wall seating will weaken the anchor.

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!

Able to drill through cement block exterior walls

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 .
