S-94061A224 Length 2 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Efficient installation through self-drilling tip design that eliminates pre-drilling requirements for materials up to 0.1" thickness
• Enhanced driving control with Phillips No. 2 drive that provides secure tool engagement and reduces cam-out incidents
• Optimal material displacement using thread forming technology that creates strong, permanent threads in steel and sheet metal
• Professional finished appearance with oval head design that sits flush with surfaces when installed with 82° countersink angle
• Maximum holding power through fully threaded design that ensures complete engagement along the entire 2-1/2" length
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for safe use in various industrial applications

Professional Applications & Engineering Value

These No. 8 zinc-plated steel tapping screws deliver exceptional performance in steel and sheet metal applications where reliability and efficiency are paramount. The thread forming design eliminates the need for separate tapping operations by displacing material to create strong, permanent threads that resist vibration loosening. The integrated drilling tip with No. 2 specification penetrates up to 0.1" thickness, significantly reducing installation time and labor costs. The oval Phillips head provides a clean, finished appearance while the zinc plating offers essential corrosion protection for extended service life in industrial environments. These BSD tapping screws are engineered to maintain integrity under stress, making them ideal for HVAC systems, metal fabrication, electrical enclosures, and structural assemblies where fastener reliability is critical.

Specification Summary & Compliance

These thread forming screws feature precise No. 8 size with 0.164" thread diameter and 18 threads per inch for optimal engagement in metal substrates. The 2-1/2" length with fully threaded design ensures maximum holding capacity, while the standard oval head profile with 82° countersink angle provides proper seating in prepared holes. Manufactured to BSD tapping screw standards with right-hand thread direction and round shank cross-section. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for industrial use.
