S-94195A150 Length 1 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Self-drilling capability eliminates pre-drilling steps, saving significant labor time and reducing tooling requirements in steel and sheet metal assemblies
• 410 stainless steel construction provides excellent corrosion resistance for durable performance in demanding industrial environments
• Thread forming design (BSD type) creates strong, secure threads in parent material without generating chips, preventing contamination in sensitive applications
• No. 2 drill tip with 3/16" length ensures clean, precise hole creation through materials up to 0.098" thick without pilot holes
• 82° countersink angle allows the flat head to sit flush with surfaces for smooth finishes and improved aesthetics
• Phillips drive with No. 2 size offers reliable torque transmission and widespread compatibility with common industrial drivers
• Fully threaded shank maximizes grip length and pull-out resistance across the entire fastener engagement area

Professional Applications & Engineering Value

These No. 8-18 self-drilling tapping screws deliver exceptional value in metal fabrication and assembly operations where speed and reliability are critical. The 410 stainless steel composition ensures corrosion resistance while maintaining the strength needed for structural applications in steel, stainless steel, and sheet metal components. The innovative thread forming action of these BSD tapping screws creates permanent, vibration-resistant connections without generating metal chips that could compromise electrical systems or moving parts. The combination of self-drilling capability and fully threaded design eliminates multiple production steps, reducing installation time by up to 50% compared to conventional fastening methods. Engineers specify these Phillips flat head screws for HVAC systems, electrical enclosures, metal building components, and industrial machinery where flush mounting and rapid installation are essential for project timelines.

Specification Summary & Compliance

These self-drilling tapping screws feature precision No. 8-18 thread with 0.164" diameter and 1-1/4" length, manufactured to industry standards for consistent performance. The flat head profile with standard dimensions ensures proper seating in prepared holes. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations guarantees environmentally responsible manufacturing and safe use across global markets, meeting the strictest industrial requirements for hazardous substance restrictions.
