1. Alloy steel introduction:

Alloy Steel is the most common material that fasteners are manufactured in. Alloy steel fasteners are often treated, coated or plated with zinc for additional corrosion resistance. Alloy steel is used for the hot dipped galvanized process, treated in a molten zinc bath which creates a tightly bonded alloy finish. Alloy steel is most often available in Grade A, Grade C, Grade 2, Grade 5 and Grade 8. Untreated alloy steel fasteners are black.

4. Bolt Grades & Head Markings:

Head markings on a bolt are a quick way to determine bolt grade. Some bolts will have additional markings that indicate the manufacturer; the most prized bolts have clean heads with limited markings.
