S-3313N41 1/2"-13 x 4" ASTM A354BD Threaded Rods

Key Features & Benefits at a Glance

• Exceptional tensile strength of 150,000 psi ensures reliable performance under heavy loads and reduces the risk of fastener failure in demanding applications.
• Superior corrosion resistance from the zinc yellow-chromate plating extends service life and maintains integrity in harsh or outdoor industrial environments.
• Precision Class 2A thread fit guarantees easy assembly and a secure, consistent connection with mating nuts, minimizing installation time and potential cross-threading.
• Full threading along the entire 4" length provides maximum flexibility for adjustment and allows for secure fastening at any point along the rod.
• High hardness (Rockwell C33) offers excellent wear resistance, maintaining thread form and strength through repeated use and disassembly.
• Compliance with ASTM A354BD ensures the rod meets rigorous industry standards for material quality and mechanical properties, providing peace of mind for critical projects.
• RoHS 3 and REACH compliance confirms the product is free from hazardous substances, making it suitable for use in regulated industries and global supply chains.

Professional Applications & Engineering Value

This 1/2"-13 UNC threaded rod is engineered to solve common industrial challenges such as structural loosening, corrosion-induced failure, and assembly inefficiency. Manufactured from zinc yellow-chromate plated steel, it provides a robust barrier against rust and chemical exposure, which is critical in applications like machinery frames, construction supports, and outdoor installations. The coarse UNC thread and Class 2A fit facilitate quick and reliable engagement, reducing labor time in high-volume assembly lines. With its fully threaded design and right-hand thread direction, it offers versatile positioning and secure load distribution, making it ideal for anchoring, bracing, and custom fabrication where high strength fasteners are non-negotiable for safety and longevity.

Specification Summary & Compliance

This threaded rod adheres to precise dimensional standards, including a Class 2A thread fit for external threads and UNC coarse threading with a size of 1/2"-13. It is manufactured in compliance with the ASTM A354BD specification, ensuring consistent material and mechanical properties. The product is confirmed to be RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting environmental and safety regulations for hazardous substances.
