Description

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.

Conquest A307 Grade A Hex Bolts are built to deliver dependable performance in general-purpose structural fastening. Designed with durability in mind, these bolts are hot dip galvanized for superior corrosion resistance—ideal for outdoor and high-moisture environments.

Whether you're securing wood-to-wood or wood-to-steel connections, these hex bolts are a staple in residential, commercial, and industrial construction. The coarse thread profile and hex head make installation efficient with standard tools, and the variety of available diameters and lengths ensures the right fit for your specific needs.

Perfect for contractors, builders, and dedicated DIYers, these bolts meet ASTM A307 Grade A specifications, ensuring reliable tensile strength and performance where it matters most.

Overall experience

The bolts are great. This review is about my overall experience working with Fasteners Plus. I needed to make a change in my order and this company went way above and beyond to accommodate me. It was going to be more expensive to return some hardware that I ordered by mistake and they simply sent the correct hardware and told me to keep the bolts I ordered in error. Great to work with!
