S-94625A112 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Enhanced security and tamper resistance with specialized T15 Torx drive that requires matching tools for installation and removal
• Efficient self-drilling capability with integrated drilling tip that penetrates up to 0.098" thickness, eliminating pre-drilling requirements
• Optimal flush mounting with 82° countersink angle and flat head design for smooth, professional finishes in steel and sheet metal applications
• Exceptional holding power through B-type thread forming design that creates strong, permanent threads in parent material
• Complete fastening coverage with fully threaded shank ensuring maximum engagement and vibration resistance
• Reliable performance in tough materials with thread forming technology that displaces rather than removes material for superior joint integrity

Professional Applications & Engineering Value

These No. 8-18 thread forming screws deliver exceptional engineering value in industrial fastening applications where security, durability, and installation efficiency are paramount. The zinc-plated steel construction provides reliable corrosion protection for long-term performance in challenging environments. The combination of tamper-resistant T15 Torx drive and self-drilling tip addresses critical pain points in assembly operations by eliminating the need for separate drilling steps while providing security against unauthorized removal. The B-type thread forming design creates stronger, more reliable threads in steel and sheet metal applications by cold-forming rather than cutting material, resulting in improved fatigue resistance and vibration-proof connections. The 82° countersink angle ensures proper seating and flush installation for professional-grade finishes in visible applications.

Specification Summary & Compliance

These tapping screws feature precise No. 8-18 thread specifications with 0.164" thread diameter and right-hand threading throughout the 3/4" length. Manufactured to industry standards for thread forming screws with B-type thread form and standard flat head profile. The zinc-plated finish provides corrosion protection while maintaining compliance with industrial fastening requirements. Suitable for applications requiring penetration up to 0.098" maximum drilling thickness in steel and sheet metal substrates.
