S-93190A878 7/8"-9 x 1 1/2" ASME B18.2.1 Super-Corrosion-Resistant 316 Stainless Steel Hex Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance in harsh environments thanks to 316 stainless steel construction
• High tensile strength of 70,000 psi ensures reliable performance under heavy loads
• Class 2A thread fit provides consistent, easy assembly with standard nuts
• Coarse UNC threading enables faster installation and reduced cross-threading risk
• External hex drive design allows for high-torque application with common tools
• Full threading along the 1-1/2" length offers maximum adjustability and grip
• Rockwell B70 hardness maintains thread integrity and resistance to wear

Professional Applications & Engineering Value

This 7/8"-9 UNC hex head screw in 316 stainless steel is engineered to solve critical challenges in demanding industrial settings. The coarse thread design and Class 2A fit significantly reduce installation time while preventing thread stripping in high-vibration applications. With exceptional corrosion resistance, it performs reliably in chemical processing, marine, and outdoor infrastructure where moisture and corrosive agents are present. The external hex drive and fully threaded construction provide superior clamping force distribution, making it ideal for heavy machinery, structural assemblies, and equipment requiring high tensile strength and long-term durability.

Specification Summary & Compliance

Manufactured to ASME B18.2.1 standards with Class 2A thread fit for consistent dimensional accuracy. This fully threaded screw features 7/8"-9 UNC coarse threading with right-hand direction and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements for environmental safety.
