Professional Applications & Engineering Value

This No. 12 x 2" stainless steel tapping screw is engineered to address common fastening challenges in plastic and wood applications, such as material cracking and poor seal integrity. The thread forming design with cutting wings creates precise threads without generating chips, reducing installation effort and enhancing joint strength in brittle substrates. Combined with the aluminum/rubber/steel conical washer, it provides a reliable seal against moisture and dust, making it ideal for outdoor construction, electrical enclosures, and assembly lines. The external hex drive allows for high-torque tightening, ensuring consistent performance in automated or manual settings, while the 18-8 stainless steel material offers excellent resistance to rust and corrosion, extending service life in humid or corrosive environments.
