S-92198A870 3/4"-10 x 12" ASME B18.2.1 18-8 Stainless Steel Hex Head Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments
• High tensile strength of 80,000 psi ensures reliable performance under heavy loads and stress
• Rockwell B70 hardness provides superior durability and resistance to wear and deformation
• Coarse UNC thread design enables faster installation and better performance in softer materials
• Class 2A thread fit guarantees consistent, precise engagement with standard nuts and tapped holes
• External hex drive and hex head allows for high-torque application with common tools
• Partial threading provides optimal clamping force distribution for structural connections

Professional Applications & Engineering Value

This 3/4"-10 UNC hex head screw delivers critical engineering solutions where corrosion resistance and structural integrity are paramount. The 18-8 stainless steel composition prevents rust and degradation in demanding environments like chemical processing, marine applications, and outdoor construction. With its coarse thread spacing and Class 2A thread fit, it ensures rapid assembly and reliable fastening in structural steel, heavy machinery, and industrial equipment. The partially threaded design concentrates clamping force where needed most, preventing joint loosening under vibration while the external hex drive accommodates high-torque installation for secure, long-lasting connections in critical infrastructure projects.

Specification Summary & Compliance
