S-98842A052 1/2"-20 x 4 ft. Threaded Rods

Key Features & Benefits at a Glance

• Exceptional tensile strength of 50,000 psi ensures reliable performance under heavy loads and reduces the risk of failure in demanding applications.
• Zinc-plated steel construction provides superior corrosion resistance, extending service life in harsh industrial environments.
• Class 1A thread fit offers easier assembly and disassembly, saving time and labor costs during installation and maintenance.
• Fully threaded 4-foot length allows for versatile cutting to custom sizes, minimizing material waste and providing flexibility for various project requirements.
• UNF fine thread spacing delivers enhanced vibration resistance and superior clamping force compared to coarse threads.
• Rockwell B61 hardness ensures excellent wear resistance and durability, maintaining thread integrity through repeated use.
• Right-hand threading provides standard, intuitive installation that aligns with common industrial practices and tooling.

Professional Applications & Engineering Value

This 1/2"-20 UNF fully threaded rod is engineered to address critical challenges in industrial assembly and construction. The zinc-plated steel material combats corrosion in moisture-prone environments, while the fine UNF thread spacing prevents loosening under vibration—a common issue in machinery and automotive applications. With its 50,000 psi tensile strength, it reliably secures structural components in HVAC systems, conveyor assemblies, and heavy equipment frameworks where failure is not an option. The fully threaded design allows precise adjustment and custom length fabrication, making it ideal for retrofit projects and custom fabrication where standard fasteners fall short.

Specification Summary & Compliance

This threaded rod meets Class 1A thread fit standards for unified national fine (UNF) threads, ensuring dimensional accuracy and interchangeability. Manufactured from high-strength steel with a Rockwell B61 hardness rating, it complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making it suitable for global industrial supply chains requiring strict material compliance.
