S-90065A263 Length 4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in demanding environments
• Efficient thread forming design creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time
• Optimal flush mounting with standard 82° flat head profile that sits perfectly countersunk in sheet metal applications
• Maximum grip strength through full threading along the entire 4" length for secure fastening in thick materials
• Precision installation compatibility with No. 21 drill bit (0.159") for accurate hole preparation and reduced material stress
• Reliable driving performance with Phillips No. 2 drive that provides secure tool engagement and prevents cam-out
• Environmental compliance assurance meeting RoHS 3 and REACH standards for safe use in regulated industries

Professional Applications & Engineering Value

These No. 10-12 thread forming screws deliver exceptional value in sheet metal fabrication and industrial assembly applications. The 18-8 stainless steel composition provides excellent resistance to corrosion and oxidation, making these Phillips flat head tapping screws ideal for outdoor equipment, HVAC systems, and electronic enclosures. The thread forming technology eliminates the need for separate tapping operations, creating stronger threads by displacing material rather than removing it. This results in superior pull-out resistance and vibration resistance in thin sheet metal applications up to 0.025" thickness. The 82° countersink angle ensures a clean, flush finish that meets professional appearance standards while the fully threaded design maximizes holding power across the entire fastener length.

Specification Summary & Compliance

These tapping screws feature precise No. 10-12 thread specifications with right-hand direction and fully threaded configuration. Manufactured to exacting standards with Class 2A thread tolerances for consistent performance. The screws are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet the latest international safety and environmental standards for industrial use.
