Professional Applications & Engineering Value

This No. 4-24 TPI thread forming screw delivers exceptional performance in sheet metal fabrication and assembly operations. The zinc-plated steel construction provides critical corrosion protection in industrial environments where moisture and chemicals are present. The thread forming A/AB type design eliminates chip formation during installation, preventing contamination in sensitive electrical and mechanical assemblies. With its 0.112" thread diameter and 24 threads per inch configuration, this fastener creates strong, vibration-resistant connections in thin-gauge materials up to 0.025" thickness. The slotted pan head ensures reliable driving with standard tools while maintaining a low-profile appearance. These tapping screws are engineered to solve common challenges in metalworking, including stripped threads, material fatigue, and installation inefficiency.

Specification Summary & Compliance

This thread forming tapping screw features precision No. 4-24 UNC thread with Class 2A tolerance standards, ensuring consistent performance and interchangeability.
