Hex bolts, 10 pieces, approx. 13cm length

Thank you for looking.
This is a set of 10 half-threaded hex bolts.
My in-laws used to run a hardware store,
but they closed it down, so I am
organizing the remaining inventory.
These items have been stored in the store's
warehouse for a long time, so they may have
storage dirt or scratches, but they are
unused.
I do not know the material or specifications.
The weight is approximately 230g.
I do not have knowledge about this product,
so I cannot answer technical questions.
Please understand this in advance.
Please check the images for dimensions.
They will be shipped in a can.
Thank you for your consideration.
