  • Phillips flat head configuration ensures flush installation and clean appearance while preventing snagging
  • Full threading along the entire 3/4" length delivers maximum grip and holding power in assembled components
  • Standardized 82° countersink angle allows for perfect seating in prepared holes without surface protrusion
  • Environmental compliance assurance meeting RoHS 3 and REACH regulations for safe industrial use

Professional Applications & Engineering Value

These No. 8 x 3/4" zinc-plated steel tapping screws are engineered specifically for sheet metal applications where reliability and corrosion resistance are paramount. The thread forming capability eliminates the need for separate tapping operations, reducing installation time and labor costs while creating strong, vibration-resistant connections. The Phillips flat head design with standard 82° countersink angle ensures seamless integration into metal surfaces, preventing snagging hazards and maintaining aerodynamic profiles. The combination of zinc plating and black corrosion-resistant coating provides dual-layer protection against environmental factors, making these A/AB type tapping screws ideal for HVAC systems, electrical enclosures, automotive components, and industrial equipment where long-term performance in challenging conditions is essential.

Specification Summary & Compliance

These thread forming screws feature precise 0.164" thread diameter with 15 TPI thread pitch and right-hand threading throughout the entire 3/4" length. The flat head configuration with standard profile and No. 2 Phillips drive ensures consistent installation performance. Manufactured to industry standards for sheet metal fasteners, they're compatible with No. 29 drill bits (0.136" diameter) and designed for 0.025" maximum drilling thickness. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations ensures safe usage across industrial applications.
