Professional Applications & Engineering Value

Engineered for industrial fastening challenges, this No. 12 tapping screw combines 18-8 Stainless Steel durability with advanced thread forming technology to eliminate stripping and material stress in plastic and wood assemblies. The cutting wings facilitate smooth entry, while the partially threaded shank ensures precise clamping force distribution. Integrated with a sealing washer (composed of aluminum, rubber, and steel layers), it provides an effective barrier against environmental contaminants, making it ideal for outdoor equipment, electrical enclosures, and automotive components where vibration resistance and corrosion protection are critical. This external hex drive screw delivers consistent performance in high-volume production settings, reducing assembly time and maintenance costs.

Specification Summary & Compliance

This tapping screw features a No. 12 size with a 1-1/4" length, 0.216" thread diameter, and approximately 11 threads per inch for standard inch-series applications.
