Professional Applications & Engineering Value

This No. 4-24 oval head tapping screw is engineered to address common challenges in sheet metal fabrication and assembly. Its thread forming capability creates strong, precise threads in ductile materials without generating chips, reducing the risk of contamination in sensitive equipment. The 18-8 stainless steel material provides excellent resistance to oxidation and corrosion, making it suitable for outdoor, marine, or chemically exposed environments. The combination of a Phillips drive and fully threaded design ensures quick installation and uniform stress distribution, preventing loosening under vibration. This screw is ideal for HVAC systems, electronic enclosures, and automotive panels where corrosion-resistant, high-strength fastening is critical.

Specification Summary & Compliance

This screw adheres to standard inch measurements with a thread diameter of 0.112" and approximately 24 threads per inch, ensuring compatibility with common sheet metal thicknesses. It is designed for use with a No. 44 drill bit (0.086" diameter) and an 82° countersink angle for proper seating. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing the absence of restricted hazardous substances. Manufactured to precise dimensional tolerances, it delivers consistent performance in thread forming applications.
