S-90920A292 3/8"-16 x 3/4" ASME B18.6.3 Alloy Steel Torx Flat Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding environments
• Enhanced torque transmission through T40 Torx drive design, reducing cam-out and tool slippage during installation
• Flush surface installation with 82° countersink angle and flat head profile for streamlined assemblies
• High-load capacity with 60,000 psi tensile strength to withstand substantial mechanical stress
• Reliable thread engagement through fully threaded UNC coarse pattern and Class 2A fit for secure fastening
• Industry-standard compatibility with 3/8"-16 thread size for broad application across industrial equipment
• Simplified inventory management with compliance to ASME B18.6.3 specifications and regulatory standards

Professional Applications & Engineering Value

These zinc-plated steel flat head screws deliver critical performance advantages in industrial assembly applications where surface flushness and high torque requirements coexist. The T40 Torx drive system prevents fastener damage during high-torque installation, while the UNC coarse threads provide rapid assembly in machinery, structural frames, and heavy equipment components. The combination of 60,000 psi tensile strength and full threading ensures uniform stress distribution, making these industrial fasteners ideal for applications requiring both structural integrity and streamlined profiles. The 82° countersink angle seamlessly integrates with standard chamfered holes, eliminating protrusions in precision assemblies.
