Professional Applications & Engineering Value

These No. 4-24 thread forming tapping screws are engineered specifically for sheet metal applications where reliable fastening is critical. The Black-Oxide Steel construction provides exceptional corrosion protection in industrial settings, while the thread forming design eliminates the need for separate tapping operations, reducing assembly time and costs. The fully threaded configuration ensures maximum engagement with thin materials, preventing loosening under vibration. The 82° countersink angle and flat head profile create seamless finishes in metal enclosures, electronic chassis, and HVAC components. These tapping screws solve common assembly challenges by combining easy installation with durable performance in sheet metal fastening scenarios.

Specification Summary & Compliance

This No. 4-24 x 5/8" tapping screw features precision thread forming with 0.112" thread diameter and 24 threads per inch, manufactured to standard inch system tolerances. The flat head design incorporates an 82° countersink angle compatible with standard sheet metal applications. Product complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in industrial and commercial applications worldwide.
