DuoPower Universal Wall Anchors for Fastenings in Concrete, Brick, Drywall and Wood, (50, Old, 5/16" x 1 5/8")

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.

These worked perfectly on thick ceramic wall tile for grab bars. Tough plastic design that locks in the hole super tight with absolutely no spinning. Great product, the only ones I will purchase from now on. Very pleased.

I use plastic anchors all of the time in my job and it’s so nice to find such a great product. Blows away all of my other anchors and it is the only one I am using from now on.

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.

the brand that I'm used to as i know they work well with no issues. typisch Deutsch go grab all sizes

Worked perfectly on my block house

Anchors for masonry can be a crapshoot. The simple extruded plastic 'cross-sections' either don't fit tight in the hole (because you wallowed out mortar too much), or get chewed by the screw going in and don't hold. Simple hard plastic ones 'snap' between the front ring and the back half if you overbury the screw. These actually seem to work due to the bimaterial design. Have in place in drills in both hollow brick and mortar, and both seemed to hold well (light weight camera mount). My go-to when I don't have good anchors is to drill, inject JB weld and wait for it to cure, then re-drill a pilot. Use the JB-weld as a 'formed in place' anchor. Which is a pain with hollow brick, not to mention introduces a 24 hr delay cycle into your mounting task. These look like they'll save me that effort.

Product is fine but Amazon delivery was LATE AGAIN

Not same as said. Screws are super big and box came damaged.

Muy buena opción y excelente relación precio/calidad.
