S-92525A154 Length 1 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Corrosion-resistant performance with 18-8 Stainless Steel construction for long-lasting reliability in demanding environments.
• Efficient thread forming technology creates strong, permanent threads in sheet metal without pre-tapped holes, reducing assembly steps.
• Secure Phillips drive engagement with No. 2 drive size ensures reliable torque transfer and reduces cam-out risk during installation.
• Optimized pan head design provides a low-profile, rounded finish with good bearing surface for stable fastening in sheet metal applications.
• Full threading along the 1-1/4" length offers maximum grip and uniform stress distribution for consistent holding power.
• Precision No. 10-16 thread form with 16 threads per inch ensures tight, vibration-resistant connections in metal assemblies.
• Environmental compliance assurance with RoHS 3 and REACH standards, making it suitable for regulated industries.

Professional Applications & Engineering Value

This Type B thread forming screw is engineered specifically for sheet metal applications, where its 18-8 Stainless Steel composition resists oxidation and chemical exposure, extending service life in harsh conditions. The thread forming (tapping) method displaces material to create strong internal threads, eliminating the need for separate tapping operations and reducing assembly time and cost. The Phillips drive and pan head work together to provide a flush, low-profile installation that minimizes protrusion risks in compact spaces. With a blunt tip and fully threaded shank, it ensures precise alignment and uniform clamping force, preventing loosening under vibration—a common challenge in automotive, HVAC, and electronic enclosure assemblies. Its compatibility with a No. 21 drill bit (0.159" diameter) further streamlines preparation, making it a go-to tapping screw for high-volume production lines.

Specification Summary & Compliance

This screw adheres to standard inch measurements with a thread diameter of 0.19" and 16 threads per inch, ensuring precise fit in pre-drilled holes. The Type B thread forming design follows industry-accepted specifications for self-tapping fasteners in metal. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted hazardous substances and supporting use in environmentally conscious manufacturing processes.
