S-90920A197 8-32 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 industrial environments
• Exceptional torque transmission through T15 Torx drive design, minimizing cam-out and tool slippage during installation
• High tensile strength rating of 60,000 psi ensures reliable performance under substantial mechanical loads
• Precision thread engagement with Class 2A UNC coarse spacing for faster assembly and reduced cross-threading risks
• Optimal flush mounting with standard 82° countersink angle that seats perfectly in chamfered holes
• Full threading coverage along the 3/4" length provides maximum grip strength across the entire fastener
• Regulatory compliance assurance meeting ASME B18.6.3 specifications and environmental standards including RoHS 3 and REACH

Professional Applications & Engineering Value

These zinc-plated steel flat head screws deliver critical performance advantages in industrial assembly applications where flush surface mounting and high-strength fastening are paramount. The combination of T15 Torx drive and UNC coarse threads addresses common installation challenges by providing superior torque transfer while enabling rapid assembly in production environments. The 82° countersink angle ensures precise seating in machined components, eliminating protrusions that could interfere with moving parts or create safety hazards. Engineered for machinery, equipment manufacturing, and metal fabrication applications, these fully threaded screws maintain consistent 60,000 psi tensile strength throughout their length, providing reliable clamping force in vibration-prone applications where fastener integrity is critical to operational safety and equipment longevity.

Specification Summary & Compliance

This 8-32 x 3/4" flat head screw features precision Class 2A thread fit with UNC coarse thread spacing and right-hand threading throughout the entire length. Manufacturing and dimensional compliance is verified against ASME B18.6.3 specifications, ensuring interchangeability and consistent performance. Environmental compliance includes adherence to RoHS 3 (2015/863/EU) restrictions on hazardous substances and REACH (EC 1907/2006) regulations for chemical safety, making these screws suitable for global industrial applications with strict environmental requirements.
