S-90065A124 Length 5/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh environments and long-term reliability
• Efficient thread forming design creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time
• Optimized for 0.1065" drill bits (No. 36) with precise 82° countersink angle for clean, flush installations in sheet metal up to 0.025" thick
• Secure Phillips No. 2 drive provides reliable torque transfer and reduces cam-out during installation
• Fully threaded shank ensures maximum grip and holding power across the entire fastener length
• Standard 82° flat head profile sits flush with material surface for smooth finishes and reduced snagging
• Environmental compliance assurance with RoHS 3 and REACH regulations for safe, sustainable industrial use

Professional Applications & Engineering Value

These No. 5-20 thread forming tapping screws deliver exceptional performance in demanding sheet metal applications where vibration resistance and material integrity are critical. The 18-8 stainless steel composition provides excellent corrosion resistance, making these Phillips flat head screws suitable for outdoor equipment, HVAC systems, and electronic enclosures exposed to moisture. The thread forming design eliminates chip removal issues common in traditional tapping, creating tighter thread engagement that resists loosening under dynamic loads. With their fully threaded configuration and precise 82° countersink angle, these fasteners ensure uniform stress distribution and flush mounting in thin-gauge materials, solving common challenges of strip-out and improper seating in sheet metal fastening applications.

Specification Summary & Compliance

This No. 5-20 x 5/8" tapping screw features a 0.125" thread diameter with 20 threads per inch in right-hand direction, manufactured to precise dimensional standards for consistent performance. The fastener complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory adherence for industrial applications. Engineered for use with No. 36 drill bits (0.1065" diameter) in materials up to 0.025" thickness, this Type A thread forming screw delivers reliable performance in professional sheet metal assembly operations.
