Опись вещей включает крепёж и защитные уголки.

Because опись usually takes the genitive to mean an inventory/list of something.

So:

• опись = inventory, itemized list
• вещей = of things / of items

This is the same basic pattern as:

• список книг = a list of books
• пачка писем = a pack of letters
• опись имущества = an inventory of property

The dictionary form is вещи for the plural things, but after опись it becomes genitive plural: вещей.

They are the direct objects of включает, so they are in the accusative case.

However, because these nouns are inanimate, their accusative forms look like the nominative forms:

• крепёж → accusative крепёж
• защитные уголки → accusative защитные уголки

So even though the case is accusative, the forms do not visibly change here.

Because the subject is singular: опись вещей.

The head noun of the subject is опись, which is singular and feminine, so the verb is singular too:

• опись ... включает = the inventory includes

Even though вещей is plural, it is not the grammatical subject. It is just part of the phrase опись вещей.

Russian often uses the present tense for general facts, definitions, document language, and descriptions of what something contains.

So Опись вещей включает... means something like:

• The inventory includes...
• The list contains...

This is not necessarily about something happening right now in time. It is just stating a fact about the inventory.

The verb here is включать / включить in the sense of to include.

In this sentence, the imperfective включает is used because it describes a general property or content of the inventory, not a one-time completed action.

Compare:

• Опись вещей включает крепёж... = The inventory includes fasteners...
• Он включил крепёж в опись. = He included the fasteners in the inventory.

The first is a statement about contents. The second is an action of adding something.

Not quite.

• список = list (general, everyday word)
• опись = inventory, itemized record, formal list

Опись sounds more official or technical. It is common in contexts like:

• shipping
• packing
• customs
• storage
• legal/property documentation

So in this sentence, опись вещей sounds more like inventory of items than just a casual list.

Крепёж is a collective/material-type noun meaning fasteners, fixings, or mounting hardware.

Depending on context, it may refer to things like:

• screws
• bolts
• nuts
• anchors
• brackets
• other fastening parts

It often behaves like a mass or collective noun in Russian, so even though English may use a plural like fasteners, Russian often uses the singular-looking form крепёж.

Literally, the phrase means protective corners.

In practical English, it often refers to corner protectors, especially in packaging or shipping. These are pieces placed on corners to protect an object during transport or storage.

So although the literal translation is protective corners, the natural English meaning may be:

• corner protectors
• protective corner pieces

Because it agrees with уголки, which is plural.

Russian adjectives must agree with the noun they describe in:

• gender
• number
• case

Here:

• уголки = plural
• therefore защитные = plural as well

Both are also in the accusative plural, but for inanimate plural nouns, that looks the same as the nominative plural.

Not exactly.

• углы = corners/angles
• уголки = little corners, corner pieces, small angled parts

The ending -к- here gives a diminutive or specialized feel. In technical and packaging contexts, уголки often means actual corner protectors or corner pieces, not just geometric corners.

So in this sentence, уголки is more natural than углы.

Russian does not have articles like the and a/an.

So Опись вещей включает крепёж... can mean:

• The inventory includes...
• An inventory includes...
• The list contains...

Which one sounds best in English depends on context, but Russian does not mark that distinction with articles.

Yes, Russian word order is more flexible than English word order.

The neutral order here is:

• Опись вещей включает крепёж и защитные уголки.

This is a normal subject + verb + object structure.

Other orders are possible for emphasis, for example:

• Крепёж и защитные уголки включает опись вещей.

That is grammatically possible, but less neutral and more marked. A learner should treat the original sentence as the standard, straightforward order.

Because и is simply joining two objects in a basic list:

• крепёж
• защитные уголки

Russian, like English, normally does not use a comma before и when it connects two items in a simple pair.

It is pronounced with stress on ё:

• крепёж = roughly krye-pyózh

The letter ё always carries stress. It is important because it tells you both the pronunciation and the stress.

In some printed Russian texts, ё is sometimes replaced by е, so you may see крепеж, but the intended pronunciation is still крепёж.

Yes, it sounds fairly formal or technical.

Words like:

• опись
• крепёж
• защитные уголки

are common in packaging, logistics, assembly instructions, warehouse records, and official descriptions of contents.

A more casual sentence might use something simpler depending on context, but this version sounds natural for an inventory or packing document.

Yes, you could say:

• Опись вещей включает в себя крепёж и защитные уголки.

That also means includes. However, включает by itself is already complete and often sounds cleaner.

So:

• включает = includes
• включает в себя = includes, contains within itself

The longer version is common, but sometimes feels slightly more wordy.

A native speaker would naturally parse it like this:

• Опись вещей = the inventory of items
• включает = includes
• крепёж и защитные уголки = fasteners and protective corner pieces

So the structure is:

[subject] + [verb] + [direct objects]

That makes it a very standard and readable sentence in Russian.
