GRADE 5 HEX CAP SCREWS ZINC, INCH (Globally Sourced)
A "grade 5 hex cap screw zinc" refers to a hexagonal head cap screw made from medium carbon steel, heat-treated to achieve a "Grade 5" strength level, and coated with a zinc plating for added corrosion resistance; essentially, it's a strong, versatile fastener with moderate corrosion protection, commonly used in various assembly applications where a balance of strength and rust resistance is needed.
Key points about a Grade 5 hex cap screw zinc:
Grade 5 strength: Indicates a higher tensile strength compared to lower grade cap screws, making it suitable for applications requiring moderate strength.
Hex head: A hexagonal shaped head that allows for easy tightening with a wrench.
Zinc plating: A protective zinc coating applied to the screw to resist corrosion.
Common applications: Automotive parts, machinery, construction, and general industrial applications where moderate corrosion resistance is needed.
Identifying features:
Head markings: Grade 5 cap screws usually have three radial lines on the head to identify their grade.
- Material: Made from medium carbon steel.
