S-94077A419 5/8"-11 x 5" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with ultra-corrosion-resistant coated steel construction for extended service life in harsh industrial environments
• Enhanced torque transmission through external hex drive design for secure installation and reduced tool slippage
• Optimized material displacement with thread forming (Type C) tapping method creates stronger threads in steel and sheet metal
• Increased bearing surface from integrated flange design distributes load evenly and eliminates need for separate washers
• Reliable coarse threading with UNC 5/8"-11 thread profile provides excellent pull-out resistance in various metal substrates
• Versatile partial threading with minimum 2 1/2" thread length allows for precise clamp-up control in multi-layer assemblies
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for environmentally responsible manufacturing

Professional Applications & Engineering Value

These 5/8"-11 UNC tapping screws deliver exceptional performance in demanding steel and sheet metal applications where vibration resistance and long-term reliability are critical. The thread forming design eliminates chip accumulation issues common in traditional tapping operations, creating clean, secure fastening points without compromising material integrity. The ultra-corrosion-resistant coated steel construction provides superior protection against environmental factors, making these hex head flange screws ideal for outdoor equipment, structural frameworks, and industrial machinery exposed to moisture or chemical agents. The combination of external hex drive and five-lobe shank cross-section ensures maximum torque transfer during installation, reducing the risk of fastener failure under heavy loads while the integrated flange provides excellent load distribution across joined surfaces.
