Professional Applications & Engineering Value

This 18-8 Stainless Steel tapping screw delivers exceptional value in sheet metal fabrication and assembly operations. The thread forming Type B design eliminates the need for pre-tapped holes, significantly reducing installation time and labor costs while creating stronger thread engagement than cutting alternatives. The fully threaded blunt tip efficiently displaces material during installation, preventing metal shavings that can contaminate sensitive equipment. With its corrosion-resistant properties and Phillips pan head configuration, this fastener maintains structural integrity in demanding environments including HVAC systems, electrical enclosures, and outdoor equipment where moisture and chemical exposure are concerns. The combination of precise thread forming and durable stainless steel construction ensures vibration resistance and long-term fastener reliability.

Specification Summary & Compliance

This No. 4-24 x 1-3/4" tapping screw features standard inch measurements with Class 2A thread tolerances for consistent fit and performance. The fastener complies with RoHS 3 (2015/863/EU) regulations, ensuring environmental safety and regulatory compliance. Manufacturing follows industry standards for thread forming Type B screws with precise dimensional control including 0.112" thread diameter, 24 threads per inch, and recommended No. 44 drill bit (0.086" diameter) for optimal performance in sheet metal applications.
