Key Features & Benefits at a Glance

  • Corrosion-resistant 18-8 stainless steel construction ensures long-term durability and reliability in harsh industrial environments
  • Integrated self-drilling tip (No. 2 drill point) eliminates pre-drilling requirements, saving time and labor costs in aluminum and sheet metal applications
  • Thread forming BSD design creates stronger, more secure fastenings with superior resistance to vibration loosening
  • Full threading along the 2" length provides maximum grip and holding power throughout the entire engagement area
  • 82° countersink flat head sits flush with material surfaces for clean, professional finishes in visible applications
  • 0.1" maximum drilling capacity handles standard gauge materials efficiently without additional tooling
  • Phillips drive (No. 2 size) offers familiar, secure tool engagement for consistent installation torque

Professional Applications & Engineering Value

These No. 8-18 self-drilling tapping screws deliver exceptional value in aluminum and sheet metal fabrication by combining drilling and fastening operations into a single step. The 18-8 stainless steel material provides excellent corrosion resistance, making these BSD tapping screws ideal for outdoor equipment, HVAC systems, and electronic enclosures where environmental factors are a concern. The thread forming design displaces material rather than removing it, creating stronger threads with improved fatigue resistance compared to conventional tapping screws. With a 0.164" thread diameter and 18 TPI configuration, these fully threaded fasteners maintain consistent clamping force across the entire 2" length, preventing joint relaxation in vibration-prone applications.

Specification Summary & Compliance

These self-drilling screws feature precision No. 8-18 thread specifications with right-hand threading and standard inch measurements. The flat head design incorporates an 82° countersink angle for proper seating in standard chamfered holes. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and workplace safety. The No. 2 drill tip with 7/32" length provides consistent penetration through materials up to 0.1" thickness, while the Phillips drive system ensures reliable torque transmission during installation.
