S-90065A321 Length 2 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in demanding industrial environments
• Efficient thread forming technology creates strong, permanent threads in sheet metal without requiring pre-tapped holes
• Optimal flush mounting with standard flat head profile and 82° countersink angle for smooth, professional finishes
• Enhanced driving efficiency through No. 3 Phillips drive design that minimizes cam-out and improves installation speed
• Maximum grip strength with fully threaded design providing continuous engagement along the entire 2-1/2" length
• Precision compatibility with 5.5 mm (0.2165") drill bits for accurate hole preparation in sheet metal up to 0.025" thickness
• Environmental compliance assurance meeting RoHS 3 and REACH standards for sustainable manufacturing practices

Professional Applications & Engineering Value

These Type A thread forming tapping screws deliver exceptional value in 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 ideal for HVAC systems, electrical enclosures, and industrial machinery exposed to harsh conditions. The thread forming design eliminates chip formation during installation, preventing contamination in sensitive assemblies while creating stronger thread engagement than cutting alternatives. With 0.242" thread diameter and 10 threads per inch, these fully threaded screws maintain consistent clamping force across the entire fastener length, ensuring reliable performance in thin-gauge materials where pull-out resistance is paramount.

Specification Summary & Compliance

These No. 14 sheet metal screws feature precision Class 2A thread tolerances with standard right-hand threading and pointed tip for easy starting. Manufacturing complies with industry-standard Type A tapping screw specifications for thread forming applications. Environmental compliance is verified through RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) certifications, ensuring these fasteners meet current regulatory requirements for hazardous substance restrictions.
