Professional Applications & Engineering Value
These Black-Oxide Steel tapping screws are engineered specifically for sheet metal applications where reliable fastening is critical. The thread forming design eliminates the need for pre-tapped holes, creating strong mating threads that resist loosening under vibration. The flat head profile with 82° countersink angle sits flush with surfaces, preventing snagging while maintaining structural integrity. Ideal for HVAC systems, electrical enclosures, and metal fabrication, these No. 6 x 3/4" screws provide exceptional tensile strength and durability in thin-gauge materials. The combination of right-hand threading and pointed tip ensures quick starts and smooth installation, reducing assembly time while maintaining consistent performance across production runs.
Specification Summary & Compliance
These tapping screws feature precise dimensional specifications including 0.138" thread diameter, 18 TPI thread pitch, and standard Class 2A thread tolerances. Manufactured as A/AB type tapping screws with fully threaded shank and No. 2 Phillips drive. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in industrial applications worldwide. Designed for use with No. 32 drill bit (0.116" diameter) as specified for optimal performance in sheet metal fastening applications.
