Professional Applications & Engineering Value

These zinc-plated steel flanged tapping screws deliver exceptional engineering value by solving critical fastening challenges in metal fabrication and assembly operations. The thread-cutting F-type design with UNC coarse threads creates precise mating threads in aluminum, brass, cast iron, and sheet metal without requiring pre-tapped holes, significantly reducing installation time and labor costs. The external hex/slotted drive system provides tooling flexibility for both high-torque applications and quick manual adjustments. The integrated flange eliminates the need for separate washers, distributing clamping force evenly while preventing material surface damage. This combination of features makes these 3/8"-16 tapping screws ideal for high-volume production environments where reliability, speed, and consistent performance are paramount.

Specification Summary & Compliance

This flanged tapping screw features precise UNC 3/8"-16 coarse threading with full thread engagement along its 5/8" length. Manufactured to Class 2A thread tolerances for reliable fit, the screw meets ASME B18.6.3 specifications (SAE J933) ensuring dimensional consistency and mechanical performance. The product is RoHS 3 (2015/863/EU) compliant for environmental safety and contains no restricted hazardous substances. Proper installation requires R drill bit (0.339" diameter) for optimal thread engagement in designated materials including aluminum, brass, cast iron, and sheet metal applications.
