• Fully threaded 1-3/4" length offers maximum grip range and holding power across various sheet metal thicknesses.
• Optimized pan head profile with 0.373" diameter provides a low-profile finish while ensuring sufficient bearing surface.
• Precision-matched drill bit compatibility with No. 21 size (0.159" diameter) ensures proper hole preparation for maximum thread engagement.
• Environmental compliance assurance with RoHS 3 and REACH regulations, meeting international standards for industrial applications.

Professional Applications & Engineering Value

These 18-8 stainless steel tapping screws deliver exceptional value in sheet metal fabrication and assembly operations. The thread forming design eliminates the need for separate tapping operations, significantly reducing labor costs and production time while creating strong, vibration-resistant connections. The A/AB tapping screw type with fully threaded configuration ensures maximum pull-out resistance in thin materials up to 0.025" thickness. The combination of stainless steel material and square drive system addresses common challenges in metalworking environments, including corrosion protection, strip-resistant installation, and consistent clamping force. These industrial fasteners are engineered to maintain integrity in demanding applications where reliability and compliance are critical.

Specification Summary & Compliance

This No. 10 tapping screw features precision 0.19" thread diameter with 12 threads per inch and 1-3/4" fully threaded length. The screw meets standard dimensional requirements for A/AB thread forming screws with right-hand threading. Manufacturing and material compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and suitability for global industrial markets.
