S-90065A290 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in harsh industrial environments
• Efficient thread forming design creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time
• Precise 82° countersink angle ensures flush mounting and clean finished appearance in sheet metal applications
• Optimized for 0.1875" drill bits with maximum 0.025" drilling thickness for consistent, reliable installations
• Full threading and pointed tip provide faster starts and superior holding power throughout the entire fastener length
• Undercut flat head profile allows for deeper seating and improved clamping force in sheet metal assemblies
• Environmental compliance assurance with RoHS 3 and REACH compliance for global manufacturing requirements

Professional Applications & Engineering Value

These 18-8 stainless steel tapping screws deliver exceptional value in sheet metal fabrication and industrial assembly applications. The thread forming Type A design eliminates the need for separate tapping operations, significantly reducing labor costs and installation time while creating stronger, more reliable threads that resist vibration loosening. The Phillips flat head configuration with 82° countersink provides a clean, flush finish that meets aesthetic requirements while the fully threaded construction ensures maximum holding power across the entire engagement length. Manufactured from corrosion-resistant 18-8 stainless steel, these tapping screws maintain integrity in demanding environments, making them ideal for HVAC systems, electronic enclosures, automotive components, and industrial equipment where reliability and compliance with environmental regulations are critical.
