S-90036A030 5/16"-18 x 3 ft. Threaded Rods

Key Features & Benefits at a Glance

• Exceptional tensile strength of 50,000 psi ensures reliable performance in high-stress applications, reducing the risk of mechanical failure
• Zinc-plated steel construction provides superior corrosion resistance, extending service life in harsh industrial environments
• Left-hand threading offers specialized functionality for applications requiring reverse rotation or safety-critical assemblies
• Class 1A thread fit delivers easier assembly and disassembly while maintaining secure fastening in non-critical applications
• Fully threaded 3-foot length provides maximum flexibility for custom cutting and versatile installation requirements
• UNC coarse thread spacing ensures quick installation and reduced cross-threading in demanding industrial settings
• Rockwell B61 hardness rating guarantees consistent durability and wear resistance throughout the rod's service life

Professional Applications & Engineering Value

This 5/16"-18 UNC left hand threaded rod delivers specialized engineering solutions where standard right-hand threads are impractical or unsafe. The zinc-plated steel construction provides essential corrosion protection for industrial environments exposed to moisture and chemicals, while the coarse thread spacing enables rapid assembly in vibration-prone applications. The left-hand threading serves critical safety functions in rotating machinery, preventing accidental loosening where conventional rotation occurs. With full threading along the entire 3-foot length, engineers gain maximum flexibility for custom fabrication, allowing precise cutting to required dimensions without compromising thread integrity. This combination of specialized threading and robust material properties makes it ideal for maintenance, repair, and OEM applications across multiple industrial sectors.

Specification Summary & Compliance
