Are Grade 5 bolts galvanized?
Grade 5 is the most common grade used in manufacturing assembly. Galvanized plating protects the bolt from corrosion; typically used in outdoor applications.
Will Grade 5 bolts rust?
Many other grades exist but are used far less often. Grade 2, 5, and 8 are usually plated with a slightly blue-ish or yellow zinc coating, or are galvanized, to resist corrosion.
What material is a Grade 5 bolt made of?

Source ASTM A449 Threaded Rods HDG Online
We provide these threaded rods in a range of thread configurations, diameters, and with hot dipped galvanized (HDG) finish for added reliability and resistance.
Will galvanized bolts rust?
Galvanized steel is coated with a thin layer of zinc. The zinc coating protects the steel beneath it from rust. It’s used to make nuts, bolts, screws, and nails resistant to degradation when they are exposed to the weather. Galvanized steel stands up to water well — as long as it’s not salt water.
