Hello,

What would be the difference between EC000089 (All-purpose plug), EC000097 (Hammerfix) and EC000364 (Screw anchor)? "Hammerfix" has "All-purpose plug" as a synonym. "Screw anchor" includes an image of a metal plug/sleeve (and the feature EF002169 "Material" only includes different kinds of metals (Steel, Brass) and Others).

In the case these classes are to be joined in the future, is the best option for now to use EC000089 (All-purpose plug) to classify these kinds of products? It's the most general one, with different types of plugs to select from in feature EF000010 "Model" and different materials to choose from in EF002169 (Material), including both Plastic and Steel.

Thanks again,

Roberto

The difference between EC000089 (All-purpose plug) and EC000097 (Hammerfix) is clear: An all-purpose plug is the classical plug, where the screw is mounted afterwards. A hammerfix is a plug that is 'hammered in' together with the screw (or nail) and then is screwed in further for final fixation. Usually the screw or nail is included, but in some cases not. Idea is I assume that it works much quicker this way. See 3 pictures attached with screw/nail and without. 

EC000364 (Screw anchor) in my opinion can hardly be confused with the 2 previous classes. It is a typical product used for example to suspend EC000028 - Threaded rod from a concrete ceiling to mount e.g. air ducts. If any confusion/overlap here it would be with EC000755 - Anchor sleeve.

better picture of the variant with a nail (can't delete the other one?)

Hello Marc, thanks very much for your explanation!

I had one more question related to this: if a product is an all-purpose plug with an L-hook screw (EC002361), my idea is that it would be inside EC000089 (All-purpose plug), and in feature EF000385 ("With screw"), which is a Logical one, indicate "true". However, the information that we're talking about an "L-Hook screw" is lost, because there is no feature to indicate which kind of screw we are talking about. Another option is to classify the product as an L-hook screw, but then it's not possible to say that a plug is included.

In this case it could be interesting either to include the feature EF001227 "With anchor/plug" in EC002361 (L-hook screw), or the other option would be to include an alphanumerical feature like "Screw type" in EC000089 (All-purpose plug). For now, I think the best option would be to classify it as an All-purpose plug "with screw". What do you think?

I attach a picture of the product I am talking about.

Thanks very much,

Roberto

Hello again,

There is another class EC011733 (Screw mounting set) which could also work here, however from the reference pictures I understand that a "screw mounting set" generally includes nuts and washers (even though there are features in this class that allow to inform that these extra pieces are not there (EF005059 - With nut, EF005076 - With washer, EF021719 - With cover).

If it's a plug with a screw only, my impression is that it should go into EC000089 (All-purpose plug) "with screw", instead of being a EC011733 (Screw mounting set) without nut, washer and cover, right? I see the first option most straightforward, even though you can't specify the type of screw.

Thanks,

Roberto

EC011733 (Screw mounting set) is not relevant here, these are special complete sets that are specifically for mounting sanitary products like toilets, wash basins, etc. For EC002361 (L-hook screw) the only good solution would be to add EF001227 "With anchor/plug" to this class. The main product is the L-hook screw, for that reason I would not want to classify it in a plug class. I opened an RFC to add the feature, which by the way I changed to "With plug", because the anchor might again confuse this with EC000009 - Hammer set anchor, that has EF005644: Fastening provision with EV008374: L-hook screw.

Hello,

I attach pictures of a plug for holding insulation boards in place (picture 1), double expansion plugs (pictures 2 and 3), and plug specifically designed for scaffolding (picture 4). However, for the time being, regarding plugs I have identified 2 classes, "EC000089 (All-purpose plug)" and "EC000097 (Hammerfix)". If I had to choose one of them, I would choose "all-purpose plug" for the time being until there are more specific classes created, would this be the correct way to proceed?

Thanks a lot,

Roberto

Hello once again,

One more question - what would a steel all-purpose plug look like? Because I generally associate them with plastic - the steel ones I associate them more with "anchor sleeves" or so. I attach a picture of a possible example of an all-purpose metal plug (picture 1), would this be it?

I also attach picture 2 (another kind of metal plug) / 3 (ceiling plug), which are also other steel plugs but which I don't know how to classify at the moment... 

Thanks again!

Hi Roberto, it gets more difficult with every topic ?. I think there should be some specific classification regarding these insulation fixating material, but I can't find it right now. The class EC000040 - Cavity fixing for sure is also relevant for the product area you are focusing on right now. I guess now for one of your customers in this field? Maybe it would be a better idea to get them into contact with a local ETIM office to be involved? I am stretching my limits here in time and knowledge ...
