Professional Applications & Engineering Value
These 18-8 stainless steel tapping screws are engineered specifically for sheet metal applications where corrosion resistance and structural integrity are critical. The thread forming design eliminates the need for pre-tapped holes, reducing installation time and labor costs while creating stronger, more reliable connections. The No. 2 square drive prevents tool slippage during high-torque installation, ensuring consistent seating and reducing fastener damage. The pan head configuration provides a low-profile finish with excellent clamping force distribution, making these A/AB type tapping screws ideal for HVAC systems, electrical enclosures, automotive components, and industrial equipment where vibration resistance and long-term performance are essential.
Specification Summary & Compliance
Manufactured to precise inch system specifications with No. 8-15 thread profile and Class 2A thread tolerances. Features include 0.164" thread diameter, 15 threads per inch, and 1-1/2" fully threaded length. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Designed for use with No. 29 drill bit (0.136" diameter) in materials up to 0.025" thickness, ensuring proper thread formation and maximum holding strength in sheet metal fastening applications.
