Professional Applications & Engineering Value

These No. 4-24 thread forming tapping screws deliver exceptional value in sheet metal assembly by addressing common industrial challenges. The zinc-plated steel material provides superior corrosion protection, extending service life in demanding environments like HVAC systems, electrical enclosures, and automotive components. The thread forming technology eliminates the need for separate tapping operations, reducing labor costs and preventing thread stripping in thin-gauge materials. With a slotted pan head design and fully threaded pointed tip, these screws ensure quick alignment and secure fastening, minimizing installation time while maintaining vibration resistance. Ideal for high-volume manufacturing, these A/AB type screws offer reliable performance where consistent clamp load and durability are critical.

Specification Summary & Compliance

This tapping screw features precise inch measurements including 0.112" thread diameter, 24 threads per inch, and 1/4" length with Class 2A thread tolerances. Manufactured as a thread forming screw with right-hand threading and round shank cross-section, it complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The screw is designed for use with No. 44 drill bit (0.086" diameter) in sheet metal applications up to 0.025" thickness, ensuring consistent performance across industrial fastening operations.
