Galvanized A307 Hex Bolts – General Purpose Bolting with Added Corrosion Protection

Galvanized A307 hex bolts offer a reliable fastening solution for general construction and structural applications where moderate corrosion resistance is required. Made from low-carbon steel and coated with a hot-dip galvanized finish, these bolts meet ASTM A307 specifications for non-critical structural connections. They're a popular choice for outdoor framing, agricultural equipment, fencing, and utility projects exposed to the elements.

The hot-dip galvanized coating adds a durable, protective layer that helps resist rust in wet or humid conditions, making these bolts ideal for exterior and semi-exposed installations. Combined with the familiar hex head design, A307 galvanized bolts are easy to install and compatible with a wide range of nuts and washers.

  • ASTM A307 Compliant: Manufactured to meet standard specs for general-purpose steel bolts
  • Hot-Dip Galvanized: Provides corrosion resistance for outdoor and exposed use
  • Versatile Applications: Great for framing, wood-to-steel connections, and agricultural or utility construction

Stocked in a wide range of sizes to meet jobsite needs. Most orders placed before 4:00pm CST ship out the same day from Fasteners Plus.
