The product obtained after this reaction is known as oleum. The oleum obtained is then dissolved in water to obtain concentrated sulphuric acid.

Degree wire welded pallet coil nails are a type of fastening hardware made from high-quality steel wire, designed specifically for use in pallet construction, fencing, and similar uses in heavy-duty applications. They are named degree nails because they are available in several degrees of angle, typically around 15 to 34 degrees, which allows them to be fed and driven efficiently using pneumatic nailers or staplers.
