S-91355A074 8-32 x 3/8" ASME B18.3, ASTM F835 Steel Flanged Button Head Hex-Drive Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with Black-Oxide finish, ideal for harsh industrial environments
• Superior tensile strength (120,000 psi) ensures reliable performance under high-stress applications
• Precise Class 3A thread fit provides secure, vibration-resistant connections in critical assemblies
• Flanged button head design eliminates need for separate washers while distributing clamping force evenly
• 3/32" hex drive compatibility allows for efficient installation with standard industrial tools
• Full threading coverage maximizes engagement depth and pull-out resistance
• Coarse UNC threading enables rapid installation and reduced cross-threading risks

Professional Applications & Engineering Value

Engineered for demanding industrial applications, these 8-32 UNC screws combine Black-Oxide Alloy Steel construction with Class 3A thread precision to solve common fastening challenges. The flanged button head design provides enhanced bearing surface that prevents material deformation in soft substrates while maintaining sleek profile clearance. With 120,000 psi tensile strength and Rockwell C39 hardness, these fully threaded screws deliver exceptional fatigue resistance in vibration-prone equipment, electrical enclosures, and machinery assemblies. The coarse thread spacing ensures quick installation in production environments while the hex drive configuration prevents cam-out during high-torque applications.
