Professional Applications & Engineering Value

These No. 6 x 3/8" stainless steel oval head tapping screws deliver exceptional value in sheet metal assembly applications where corrosion resistance and thread integrity are critical. The 18-8 stainless steel material provides superior protection against rust and chemical exposure, while the thread forming Type A/AB design eliminates the need for tapped holes by cold-forming mating threads directly into the material. This creates stronger, more vibration-resistant connections compared to traditional cutting screws. The oval head profile offers an attractive finish with improved countersinking capability, making these industrial fasteners ideal for HVAC systems, electronic enclosures, and metal fabrication where both performance and aesthetics matter. With 18 TPI precision threading and right-hand direction, these screws ensure consistent, reliable performance in high-volume manufacturing environments.

Specification Summary & Compliance

These tapping screws feature precise No. 6 size with 0.138" thread diameter and 3/8" length, manufactured to exacting standards for consistent performance. The thread forming technology follows industry-standard Type A/AB specifications, ensuring proper thread engagement in sheet metal applications. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making them suitable for global manufacturing and export requirements. The fully threaded design with pointed tip and standard oval head profile provides reliable installation performance across various sheet metal thicknesses up to 0.025".
