Grade 5 bolts and fasteners are highly reliable structural components manufactured from medium-strength carbon steel. They are strictly specified under the standards set by the Society of Automotive Engineers (SAE). In the field, Grade 5 bolts can easily be identified by the three distinct radial marks stamped on the head of the bolt.
To ensure consistent strength and durability, our Grade 5 bolts are heat-treated in a controlled atmosphere. They are available in sizes ranging from ¼ inch through 1-½ inches in diameter. Key specifications include:
While Grade 5 bolts offer exceptional strength for general commercial and industrial use, if your application calls for fastening heavier materials, you may need to upgrade to Grade 8 bolts. Grade 8 bolts are the hardest and strongest option available, making them the standard for extreme, heavy manufacturing applications. However, for standard load-bearing requirements, Grade 5 bolts are the perfect, cost-effective solution.
To provide additional protection against rust and environmental wear, each Grade 5 bolt from U-Bolt-It is available in a high-quality zinc-plated finish.
