• High-strength performance delivering 70,000 psi tensile strength and Rockwell B70 hardness for demanding applications
• Exceptional thread reliability with Class 3A thread fit ensuring consistent engagement and vibration resistance
• Optimized installation efficiency through 5/64" hex drive design providing secure tool engagement and torque transmission
• Versatile partial threading allowing precise clamping control while maintaining unthreaded shank strength
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for global industrial applications

Professional Applications & Engineering Value

These 6-32 UNC flat head screws deliver exceptional engineering value in industrial fastening applications where corrosion resistance, precise flush mounting, and reliable thread engagement are critical. The 18-8 stainless steel construction with passivated finish provides superior protection against chemical exposure and environmental degradation, making them ideal for machinery, electronic enclosures, and automotive components. The Class 3A thread fit with coarse thread spacing ensures rapid assembly and secure fastening in vibration-prone environments, while the undercut flat head profile and 100° countersink angle prevent surface protrusion in precision applications. The partial threading design offers controlled clamping force distribution, preventing material distortion in thin-section assemblies.

Specification Summary & Compliance

Manufactured to precise dimensional standards with Class 3A thread fit tolerance and UNC thread form specifications. The screws feature a right-hand thread direction with coarse thread spacing, 0.138" thread diameter, and minimum 0.67" thread length. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global industrial markets and restricted substance requirements.
