Heavy-Duty Structural Bolts

Beyond standard structural bolts, Fasteners Etc., Inc. also provides a selection of tension control bolts, commonly known as TC Bolts. These high-strength structural fasteners arrive as a pre-assembled unit, including the bolt, washer, and heavy hex nut, streamlining your structural connections. Each TC bolt features a rounded bolt head and a specialized tip on the threaded shaft. During installation, this tip shears off once the precise tension has been applied, ensuring consistent durability and integrity for every structural bolt installed.

For specific strength requirements, our ASTM A325 bolts offer a robust 120,000 PSI tensile strength, while ASTM A490 bolts deliver an even higher 150,000 PSI tensile strength, perfect for the most demanding heavy-duty construction projects.
