S-92245A916 3/8"-16 x 1/2" FF-S-85, MS35307-355 Mil. Spec. 18-8 Stainless Steel Hex Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with passivated 18-8 stainless steel construction, ideal for harsh industrial environments
• High tensile strength of 70,000 psi ensures reliable load-bearing capacity and joint integrity under stress
• Class 2A thread fit provides consistent assembly with standard nuts while allowing for easier disassembly
• External hex drive design enables high-torque installation using common tools without stripping
• Fully threaded shank maximizes engagement depth and distributes clamping force evenly
• Coarse UNC threading resists vibration loosening and enables quick installation in various materials
• Rockwell B74 hardness maintains thread form and drive integrity through repeated use

Professional Applications & Engineering Value

This 3/8"-16 UNC hex head screw delivers exceptional performance in demanding applications where corrosion resistance and mechanical reliability are critical. The passivated 18-8 stainless steel construction provides superior protection against chemical exposure and atmospheric corrosion, making it ideal for marine, chemical processing, and outdoor equipment applications. The combination of coarse thread spacing and Class 2A thread fit ensures rapid assembly while maintaining vibration resistance in machinery, structural frameworks, and heavy equipment. The external hex drive accommodates standard wrenches for high-torque applications where socket head screws may be impractical. With full threading along the entire 1/2" length, this fastener maximizes thread engagement in both thick and thin materials, providing consistent clamping force across diverse joint configurations.
