Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in demanding environments
- Efficient thread forming design creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time
- Clean, finished appearance with oval head design that sits flush with material surface for professional results
- Secure Phillips No. 2 drive provides excellent torque transfer and prevents cam-out during installation
- Full threading along 1-1/4" length ensures maximum grip and holding power throughout the entire fastener
- Environmental compliance assurance with RoHS 3 and REACH compliance for safe, regulated use in industrial applications
- Optimized for 0.025" maximum drilling thickness with precise No. 32 drill bit compatibility for consistent performance
Professional Applications & Engineering Value
These No. 6 x 1-1/4" 18-8 stainless steel oval head tapping screws deliver exceptional value in sheet metal applications where corrosion resistance and structural integrity are paramount. The thread forming tapping method (Type A/AB) creates durable, vibration-resistant connections by displacing material rather than removing it, resulting in stronger thread engagement. The 82° countersink angle and oval head profile provide a smooth, finished appearance while the fully threaded design ensures maximum holding power across the entire 1-1/4" length. Ideal for HVAC systems, electronic enclosures, and metal fabrication projects requiring reliable, long-term fastening solutions.
Specification Summary & Compliance
These tapping screws feature precise 0.138" thread diameter with 18 threads per inch and right-hand threading. The oval head design measures 0.262" in diameter with standard profile, compatible with No. 32 drill bits (0.116" diameter). Manufactured to industry standards for thread forming screws, these fasteners are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory adherence for industrial use.
