S-95638A197 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Tamper-resistant T15 Torx drive prevents unauthorized removal for enhanced security in sensitive applications
• 18-8 stainless steel construction provides excellent corrosion resistance for long-term durability in harsh environments
• Thread forming design creates strong, permanent threads in sheet metal without requiring pre-tapped holes
• Fully threaded shank ensures maximum grip and holding power across the entire fastener length
• Optimized for No. 29 drill bits (0.136" diameter) with precise sizing for reliable installation in sheet metal up to 0.025" thickness
• Rounded button head profile offers a clean, finished appearance while minimizing snagging hazards
• Right-hand threading with 15 TPI delivers consistent, reliable fastening performance in industrial settings

Professional Applications & Engineering Value

These No. 8-15 thread forming screws are engineered specifically for sheet metal applications where security and corrosion resistance are paramount. The 18-8 stainless steel composition withstands environmental exposure while the tamper-resistant Torx drive (T15 size) prevents unauthorized access in public fixtures, electrical enclosures, and machinery guards. The thread forming design eliminates the need for tapping operations, reducing installation time and creating stronger thread engagement by displacing material rather than removing it. This makes them ideal for metalworking projects requiring secure, permanent fastening in thin gauge materials up to 0.025" thickness when used with the recommended No. 29 drill bit.

Specification Summary & Compliance

These tapping screws feature a No. 8 size with 0.164" thread diameter and 15 threads per inch, conforming to A/AB screw type standards for thread forming applications. The 3/4" length and fully threaded design ensure consistent performance, while the right-hand thread direction follows industry conventions. Manufactured from 18-8 stainless steel, these fasteners meet corrosion resistance requirements and are suitable for various industrial environments. The tamper-resistant Torx drive provides security compliance for applications requiring controlled access.
