S-94195A407 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Self-drilling capability eliminates pre-drilling steps, saving time and labor costs in steel and sheet metal assembly
• 410 stainless steel construction provides excellent corrosion resistance for long-term durability in demanding industrial environments
• Thread forming BSD design creates strong, secure threads in metal substrates without chip removal
• Specialized No. 2 drill tip efficiently penetrates up to 0.08" thickness in steel, stainless steel, and sheet metal
• 82° countersink angle ensures flush installation with standard flat head profiles for clean, professional finishes
• Phillips drive with No. 2 size offers widespread compatibility with common industrial tools and drivers
• Fully threaded design maximizes grip length and holding power across the entire fastener length

Professional Applications & Engineering Value

These No. 4-24 self-drilling tapping screws solve critical assembly challenges in metal fabrication and industrial manufacturing. The 410 stainless steel composition provides superior corrosion resistance compared to carbon steel alternatives, while the thread forming BSD design creates permanent, vibration-resistant connections without generating metal chips that could compromise electrical systems or moving parts. The integrated drill tip with No. 2 specification penetrates up to 0.08" thickness in steel, stainless steel, and sheet metal applications, eliminating secondary drilling operations and reducing installation time by up to 50%. The Phillips flat head configuration ensures secure driving and flush mounting in countersunk applications, making these self-drilling screws ideal for HVAC systems, electrical enclosures, metal framing, and automotive assemblies where speed, reliability, and corrosion resistance are paramount.

Specification Summary & Compliance

These tapping screws feature precision No. 4-24 thread size with right-hand threading and Class 2A thread tolerances for consistent performance. The BSD (British Standard Drilling) thread forming design ensures reliable fastening in metal substrates without pre-tapping. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, guaranteeing safe use in industrial applications worldwide. The 3/4" length and fully threaded configuration provide optimal engagement depth for secure fastening in various material thicknesses.
