S-90090A323 Length 3" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments and extended service life
• Efficient thread forming design creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time and labor costs
• Optimized for 0.025" maximum drilling thickness applications, providing reliable fastening in thin sheet metal assemblies
• Pan head with one-way drive style offers secure tamper-resistant installation and flush seating for smooth surface profiles
• Precise thread engagement with 10 threads per inch and No. 14 diameter ensures consistent clamping force and vibration resistance
• Partially threaded shank design allows for material compression control and prevents joint loosening under dynamic loads
• Environmental compliance assurance with RoHS 3 and REACH regulations for global supply chain acceptance

Professional Applications & Engineering Value

These 18-8 stainless steel thread forming screws solve critical challenges in sheet metal fabrication and industrial assembly. The A/AB tapping screw type with thread forming capability eliminates the need for separate tapping operations, significantly reducing production time while creating stronger thread engagement than cutting alternatives. The pan head design with one-way drive provides tamper-resistant security in public-facing or safety-critical applications. With corrosion-resistant stainless steel construction, these fasteners maintain integrity in humid, chemical, or outdoor environments where carbon steel would fail. The combination of 0.242" thread diameter and 10 threads per inch delivers optimal pull-out strength in thin gauge materials up to 0.025" maximum drilling thickness, making them ideal for HVAC systems, electronic enclosures, and automotive panels where vibration resistance and long-term reliability are paramount.

Specification Summary & Compliance

These No. 14 sheet metal tapping screws feature inch system measurements with 3" length and partially threaded configuration. The thread forming design follows industry-standard A/AB tapping screw type specifications with right hand thread direction. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring unrestricted use in global markets. Recommended for use with 5.5 mm drill bit (0.2165") for proper hole preparation and optimal performance in sheet metal applications.
