3/4″ x 2″ Conquest A325 Type 1 Heavy Hex Structural Bolt with Hot Dip Galvanized Finish

When pairing a nut with a hex bolt, the material and finish must match. If these do not match, the nut will not fit the bolt.

The 3/4″ Conquest A325 Type 1 Heavy Hex Structural Bolt is built for strength and durability in demanding steel-to-steel applications. Engineered to ASTM F3125 / A325 Type 1 standards, this bolt is a trusted choice for bridge building, highway infrastructure, and large-scale steel construction projects.

3/4″ Hex Structural Bolts Designed for High-Strength Structural Fastening

With a coarse 10 threads per inch and a heavy hex head, this bolt delivers exceptional clamping force and vibration resistance. The hot dip galvanized coating protects against corrosion, making it suitable for outdoor and harsh environments.

Key Features

• 3/4″ Diameter Heavy Hex Bolt: Provides structural-grade fastening for high-load applications.
