Professional Applications & Engineering Value
These thread forming tapping screws are engineered specifically for sheet metal applications where reliable fastening is critical. The Black-Oxide Steel construction provides essential corrosion protection while the Phillips oval head design offers both aesthetic appeal and functional flush mounting. The A/AB thread forming technology eliminates the need for pre-tapped holes, creating strong internal threads that resist vibration loosening. With 0.164" thread diameter and 15 TPI precision, these screws deliver exceptional pull-out strength in thin materials, making them ideal for HVAC systems, electronic enclosures, and automotive panels where material integrity cannot be compromised by traditional cutting screws.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 2A thread tolerances and right-hand threading. These No. 8 tapping screws feature standard oval head profile with 82° countersink angle and are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The thread forming design follows industry-standard tapping screw specifications for consistent performance in sheet metal applications requiring No. 29 drill bit (0.136" diameter) preparation.
