Professional Applications & Engineering Value
These thread forming tapping screws deliver exceptional value in sheet metal applications where vibration resistance and permanent fastening are critical. The black-oxide steel construction provides superior corrosion protection while maintaining the material's inherent strength. The A/AB thread forming design eliminates the need for pre-tapped holes, reducing installation time and labor costs. The fully threaded configuration and 18 TPI precision ensure maximum thread engagement and pull-out resistance. The oval head with 82° countersink creates a smooth, finished appearance while preventing snagging in assembly line operations. These features make these Phillips oval head screws ideal for HVAC systems, electrical enclosures, and automotive components where reliability and aesthetics matter.
Specification Summary & Compliance
These No. 6 x 1-1/4" tapping screws feature precise inch system measurements with 0.138" thread diameter and 18 TPI thread pitch. The thread forming tapping method follows industry standards for sheet metal fastening applications. Manufacturing compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and global market acceptance. The screws are designed for use with No. 32 drill bits (0.116" diameter) and accommodate maximum material thickness of 0.025" for optimal performance in various industrial settings.
