A325 Heavy Hex Bolts

If you need bolts for a heavy-duty application, A325 heavy hex bolts are an ideal choice. Stronger than regular hex bolts, they provide exceptional durability and longevity. With their hex head shape, they can be securely tightened for maximum reliability when it matters most. 

When you order A325 heavy hex bolts, you'll be ordering the best bolts on the market for steel applications. With your choice of size and coating, you're sure to find the perfect match for your unique requirements — whether you're tackling a DIY project or stocking up on supplies for your construction business. 

What Is an A325 Heavy Hex Bolt?

A heavy hex bolt is a steel bolt with a hex-shaped head that is larger, heavier and thicker than standard hex bolts. Their bigger size provides a greater bearing surface area so the load can be more widely distributed for safer and more secure connections. 

A325 is an ASTM (American Society for Testing and Materials) classification for heavy hex bolts with diameters ranging from 0.5 inch to 1.5 inches. It is the most common type of heavy hex bolt.

At FMW Fasteners, we carry heavy hex bolts that are uncoated or hot-dipped galvanized. Hot-dipped galvanized bolts offer the thickest possible coating for enhanced durability and corrosion resistance, making them especially ideal for outdoor and underwater applications. 

What Are Heavy Hex Bolts Used For?

Heavy hex bolts can be used for many applications that require steel-to-steel connections. With their partially threaded shafts that feature shorter threads than conventional bolts, these A325 heavy hex bolts provide enhanced structural connections that are crucial for work such as scaffolding and mating l-beams. 

Because they are specifically designed for steel structural joints, they are commonly used in the construction of bridges, buildings and highways. They are also essential in numerous other industries, including:

• - Water treatment
• - Renewable energy
• - Railroad systems
• - Steel fabrication
