S-91187A204 5/16"-18 x 2" ASTM A193 Threaded Rods

Key Features & Benefits at a Glance

• Exceptional corrosion resistance from 18-8 stainless steel construction, ideal for harsh environments and long-term reliability.
• High tensile strength of 70,000 PSI provides dependable load-bearing capacity for demanding industrial applications.
• ASTM A193 Grade B8 certification ensures material quality and performance consistency for critical assemblies.
• Class 2A thread fit offers optimal assembly clearance for faster installation without sacrificing holding power.
• Coarse UNC threading delivers superior resistance to vibration loosening and cross-threading in heavy-duty use.
• Full threading along the 2" length allows for maximum adjustability and secure fastening at any point.
• Full regulatory compliance with RoHS 3 and REACH standards for safe use in regulated industries.

Professional Applications & Engineering Value

This 5/16"-18 UNC fully threaded rod solves critical challenges in machinery assembly, structural framing, and chemical processing equipment where corrosion resistance and high tensile strength are non-negotiable. Engineered from 18-8 Stainless Steel per ASTM A193 Grade B8, it withstands aggressive environments that would degrade ordinary fasteners. The coarse UNC thread profile maintains integrity under vibration, while the Class 2A thread fit accelerates production line assembly. Its 70,000 PSI tensile strength makes it suitable for load-bearing structures, pressure vessels, and OEM equipment requiring ASTM-standard compliance and documented material traceability.
