• Maximum holding power achieved through full threading along the entire 3/16" length, providing superior grip in thin materials
• Precision compatibility with No. 44 drill bit (0.086" diameter), ensuring perfect fit and reduced installation errors
• Environmental compliance with RoHS 3 standards, meeting international regulatory requirements for hazardous substances
• Right-hand threading design for standard installation procedures, improving assembly efficiency and worker familiarity

Professional Applications & Engineering Value

These zinc-plated steel tapping screws deliver exceptional performance in sheet metal applications where reliable fastening is critical. The thread-forming B type design eliminates the need for separate tapping operations, significantly reducing assembly time and labor costs in high-volume manufacturing. The Phillips pan head configuration provides optimal torque transmission while maintaining a low-profile appearance, making these industrial screws ideal for electronics enclosures, HVAC systems, and automotive components where space constraints exist. The fully threaded construction ensures maximum thread engagement in thin-gauge materials, preventing loosening from vibration and thermal cycling. Engineered for precision, these metalworking fasteners work seamlessly with standard No. 44 drill bits, creating secure, permanent connections in various sheet metal thicknesses.

Specification Summary & Compliance

This No. 4-24 x 3/16" tapping screw features precision thread forming with standard right-hand threading and blunt tip design. Manufactured to exacting dimensional standards with Class 2A thread tolerance for consistent performance. The product is fully RoHS 3 (2015/863/EU) compliant, meeting international environmental regulations for hazardous substance restrictions. Designed specifically for use with No. 44 drill bits (0.086" diameter) in sheet metal applications, ensuring proper hole sizing and thread formation. The zinc-plated steel construction provides corrosion protection while maintaining the mechanical strength required for demanding industrial fastening applications.
