S-92790A678 1"-8 x 3" ASTM A193 Super-Corrosion-Resistant 316 Stainless Steel Heavy Hex Head Screws for High-Pressure Applications

Key Features & Benefits at a Glance

• Superior corrosion resistance from 316 stainless steel construction ensures long-term reliability in harsh chemical and marine environments
• High-strength performance with 75,000 psi tensile strength and Rockwell B96 hardness for demanding industrial applications
• Precision thread engagement with Class 2A fit and UNC coarse threading provides reliable fastening and easier assembly
• Optimized load distribution through partial threading design maximizes grip strength across the 3/4" grip length
• Industry-standard compliance with ASTM A193 and Grade B8M specifications guarantees consistent quality and performance
• Secure external hex drive allows for high-torque installation with standard tools while preventing stripping
• Dimensional stability with precise 3" length and 1 5/8" head width ensures proper fit in designed applications

Professional Applications & Engineering Value

This 316 stainless steel hex head screw delivers exceptional engineering value where corrosion resistance and mechanical strength are critical. The ASTM Grade B8M classification and ASTM A193 compliance make it ideal for chemical processing equipment, marine hardware, and high-temperature applications where standard fasteners would fail. The coarse UNC threading and Class 2A thread fit provide superior vibration resistance while allowing for quicker installation in industrial assembly lines. The partially threaded design concentrates strength where needed most, preventing thread damage during repeated disassembly. With 75,000 psi tensile strength and external hex drive, this fastener withstands extreme mechanical stresses while maintaining easy serviceability in confined spaces.

Specification Summary & Compliance

This 1"-8 UNC hex head screw features precise Class 2A thread fit tolerances and coarse thread spacing per unified thread standards. Manufacturing complies with ASTM A193 specification for high-temperature service and ASTM Grade B8M requirements for corrosion-resistant applications. The inch system measurement ensures compatibility with North American industrial equipment. Materials meet industry standards for chemical resistance and mechanical performance in demanding environments.
