Heavy-Duty Structural Bolts

Your Trusted Structural Bolt Provider: Serving Illinois & Shipping Online

At Fasteners Etc., Inc., we proudly supply high-quality structural bolts specifically engineered for demanding heavy-duty industrial and construction applications. Our extensive inventory ensures you'll find the right fasteners for your project's exact specifications.  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.
 
We stock a comprehensive range of sizes and grades, including ASTM A325 bolts and ASTM A490 bolts, known for their exceptional tensile strength and durability in critical structural connections. 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.These heavy hex structural bolts are available in various finishes, like hot-dip galvanized for superior corrosion resistance, as well as plain finish for diverse needs.
 
As a veteran-owned business based in Illinois, Fasteners Etc., Inc. is deeply committed to delivering outstanding customer service, fast shipping, and competitive volume pricing. We're your reliable, full-service distributor for all your structural fasteners and broader industrial fastening solutions.
