FAQs
The common grades of carbon steel fasteners are Grade 2, Grade 5, and Grade 8. Grade 2 is basic with low tensile strength, used for lighter applications.
Carbon present in steel is typically reduced so that it fits into three main categories of carbon steel: low (or mild), medium and high carbon steel. in paragraphs
Carbon steel fasteners come with various coatings like chrome plating, hot-dip galvanizing, and zinc plating, which enhance corrosion resistance and wear protection for diverse applications.
