How much weight can ribbed plastic anchors hold?

Weight of a backpack

While wall plugs are not as popular or even more popular than plastic anchors if they are better rated? I have never received them in purchased products, they have always been plastic anchors. Personally, I find that they would just slide off (especially from the ceiling) as they seem to be soft on the outside.

So, I’m curious as to why one would use plastic anchors when ribbed anchors seem to be better, and why use ribbed anchors when wall plugs are rated for heavier stuff.

I appreciate any thoughts on that!Mattman944Many of the anchors in your image are for drywall and/or hollow walls and won’t work in solid concrete.igorjrr@ Mattman944I edited the image to show only those I wrote about.Thanks!Solar MikeThe fact that you removed some doesn’t mean they will work or be safe for the intended purpose. You don’t mention a load.FreemanIf you go for a walk down the “screw aisle” of your local big box store, you won’t see any of those (except maybe the lag protector) in the section devoted to anchoring particular things.

It is the link between the past and the present, as well as a reference book for engineering. Its fundamental role in ancient works and present interventions, makes research, study and the application of techniques permanent and daily, so that we can continue to enjoy a legacy, universally positioned and that today is enjoyed with greater interest.

Structures are a fundamental element to achieve the necessary safety of the constructions that support them, both building and civil engineering, and, consequently, that of the users who use them.

Among the different materials used in their construction, concrete and steel are the most common, so the design and construction of concrete, steel and mixed (concrete and steel) structures is of special relevance in order to achieve such safety.

The Structural Concrete Instruction (EHE-08), approved by Royal Decree 1247/2008, of July 18, 2008, has been constituting, since its entry into force, the framework in which the requirements to be taken into account in the design and execution of concrete structures, both for building and civil engineering, are established in order to achieve the safety levels appropriate to their purpose.

Likewise, the Structural Steel Instruction (EAE), approved by Royal Decree 751/2011, of May 27, constitutes the regulatory framework establishing the requirements to be met by steel structures to satisfy structural safety and fire safety requirements, in addition to environmental protection, providing procedures that allow demonstrating their compliance with sufficient technical guarantees. These requirements must be met in the design and construction of steel structures, as well as in their maintenance.
