Frequently Asked Questions
What is the difference between Grade 5 and Grade 8?
Grade 5 (medium carbon steel, 120 ksi tensile strength) is suitable for most industrial applications. Grade 8 (alloy steel, 150 ksi tensile strength) is used for high-strength applications like automotive suspension and machinery. Grade 5 hex heads have 3 radial lines; Grade 8 has 6 radial lines.
How long will the galvanized coating last outdoors?
Hot Dipped Galvanized fasteners have a thick zinc coating that provides excellent outdoor corrosion protection — typically 20-50+ years in moderate environments. For coastal/marine use, consider stainless steel for longer life.
