- Environmental compliance meets RoHS 3 and REACH standards for safe usage in regulated industries
Professional Applications & Engineering Value
These black-oxide steel thread forming tapping screws are engineered specifically for sheet metal applications where traditional fastening methods may fail. The A/AB thread forming design displaces material rather than cutting it, creating stronger threads with superior resistance to vibration loosening. This makes them ideal for industrial fastening in HVAC systems, electronic enclosures, and metal fabrication where reliable performance is critical. The combination of fully threaded shank and pointed tip ensures quick penetration and maximum thread engagement in materials up to 0.025" thickness, while the Phillips drive system provides consistent installation torque for production line efficiency.
Specification Summary & Compliance
These No. 8 x 2" tapping screws feature a 0.164" thread diameter with 15 threads per inch, manufactured to standard inch system tolerances. The thread forming tapping method (Type A/AB) and right-hand threading ensure compatibility with standard sheet metal applications. For proper installation, use with No. 29 drill bit (0.136" diameter) as specified. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making them suitable for use in regulated industries and international markets.
